History of Iron and Steel Making: Part Two

Abstract:
In the Voelklingen Ironworks, which was founded in 1883 and now is awarded the status of a World Cultural Heritage by UNESCO, history of creating the wind element can be seen directly. The heart of the entire plant is over 6000 m² (65000 sq feet) large blowerhouse, in which gigantic machines produced the blast necessary for iron making.

Fire, water and wind are the essential elements of the ironworks. The wind fans the fire and gives it the power to melt the iron; the cooling effects of the water holds the destructive power of fire under control.

In the Voelklingen Ironworks, which was founded in 1883 and now is awarded the status of a World Cultural Heritage by UNESCO, history of creating the wind element can be seen directly. The heart of the entire plant is over 6000 m² (65000 sq feet) large blowerhouse, in which gigantic machines produced the blast necessary for iron making.

Figure 1. The Voelklingen Ironworks, now a World Cultural Heritage protected by UNESCO.
The blasting engines
The striking idea for the new technology was late in coming, but it was to revolutionize iron production: in 1878 German engineers Otto and Langen constructed the first gas motor. The mechanical engineering works Deutz builds the first the first blast furnace gas engine in 1894.

It was an ingenious innovation: at last it was now possible to use the gas, which was produced by the blast furnace in gigantic quantities in the process of smelting iron, to drive engines. The iron and steel industry was now able to recycle waste material.

Voelklingen Ironworks puts the new technology to use at once. The first large scale gas engine was ordered from M.A.N. in Nuremberg in 1899, as a generator unit for electricity, and went into operation in 1901. A total of 30 gas engines were in operation in Voelklingen Ironworks, and they were not only used not only as blast engines and power generators, but also to drive pumps and rolling mills.

In July 1903 Ironworks ordered the oldest surviving machine in the hall from the Augsburg-Nuernberg mechanical engineering works "at a price of 300 000 marks, transported by rail to Voelklingen station, fully installed and assembled and including one week of test operation". The gas engine was a twin blaster: two units were linked by a flywheel. This was latter put to a good use: when an irreparable damage occurred on a part of the twins in 1968, this part served as a "spare parts warehouse".

Another three gas engines were ordered from Thyssen AG in 1906, and the blast capacity of the Ironworks was dramatically increased with the commissioning of the engines in 1908. At that time, there was still no crane available for installing the colossus, and Hermann Roehling, the owner of the Ironworks, included the instruction that "the heaviest parts are to be transported using our available tools" in the contract. Those machines were producing blast until 80`s, when the Ironworks were shut down.

Figure 2. Blasting engine: a front look.

The rest of the engines were acquired until early 40`s. They could produce either electricity or air blast as required. When the blast furnaces needed less air blast, the machines were used to generate electricity for the Ironworks own power grid. To do this, the gas engines had to be driven at a higher speed, and the operators then received a wage bonus.
Figure 3. A view on the blasting hall.

These ten blast engines produced up to 110000 cubic meters of blast air per hour for each blast furnace in the Steelworks. The cold airflow was forced into the blast air heaters along six pipelines. Hot stones in the air heaters heated the air up to 1100°C.

The hot air entered the smelting zone of the furnace through 16 blast openings. This raised the temperature of the glowing mass up to 2000°C. The oxygen blown in combined with the carbon from the coke and left the furnace flue as blast furnace gas. The blast furnace gas was then cleaned of dust and ash and taken back to the blasting hall, where it was used to drive the blasting engines. The circulation loop was closed.

Working in the blasting hall
The blasting hall had a 12-men shift. Each blast engine has its own operator. The flywheels rotated and dispersed an uninterrupted fine oil spray into the hall which was inhaled by the operators while they worked. In addition to this came the noise of the blast engines, monotonous rhythm of the engines and hum of the flywheels as they rotated.
Figure 4. A blast engine flywheel.

The men worked extra shifts when malfunctions occurred: heavy machine parts and outsized tools had to be moved. There were no fixed break times and operators generally ate the food they brought with them towards the middle of the shift. They also kept their eyes on the machine while they ate: there was a simple table and chair next to the each blast engine. Only from the mid 1970`s, a break room offered protection from noise and oil.

The operators in the blasting hall worked for a long time worked a three-shift system. This was a constant round of early, day and night shifts, 56 hours a week without a single day off. When the pattern changed a "long shift" had to be done, working through from midday on Sunday to Monday morning. In 1960 a four-shift system was introduced. After working seven days a worker had a couple days free-- time for himself and his family.

Starting up and shutting down, oiling and monitoring the blast was the daily routine of the machine operators. But each shift has its own special tasks. The early shift was responsible for cleaning the machines. All parts were cleaned with a mixture of oil and petroleum. The cleaning of the cellar and the maintenance of spare parts was the task of day shift. The night shift ended by scrubbing the hall floor with potassium soap.

PORTABLE CABLE TOOL DRILLING MACHINES

Opening Remarks

An abandoned drilling machine is a choice find in the older oilfields. The author has stumbled across several of them in the deep forest and some were even spotted in open fields while driving country roads. These are the portable cable tool rigs that came on the scene in the late 1880's and 90's, became plentiful in the first half of the 20th century, and persist unto today.

Deserted drilling rigs, usually of the spudder type, provide a classroom for study even though they are in various stages of degradation. For different reasons, some were suddenly abandoned in mid-duty at the very site where they were drilling or working over a well. It is not uncommon to find a rig with the wire cable partly spooled and one end still fastened to tools in the hole. They were victims of an economic bust where the operator ran out of money and the next tower didn't come to work.

Among the old portable makes that the author has found in the early oilfields are the Wolfe, Star, Cyclone, Bolles, Bucyrus-Erie, Keystone drill, Yo Yo rig, Chicago Pneumatic, Ohio Cleaner, and, of course, home made varieties. Other makes that were common are the National, Leidecker, and the Columbia Driller (Oil Well Supply). There are more, some being extremely rare or just were not used in the Appalachian fields (where I am). Inventions and patents by Downie, father of the Keystone drill, in the 1880's and by H.S. and C.E. Glenn (Butler Co., Pa.) in the early 1890's helped the evolution of the portable cable tool rigs, as did Corbett even earlier (1880) who built a skid-mounted rig to drill 600 feet or more. Ideas by a few, even a patent by W. Hyde, leading to practical wheel-mounted portable rigs can be traced to the 1860's.

Most self-propelled portable rigs with wheels employed steam as the propelling force and for the drilling, at first. Some of these rigs had the boiler and steam engine mounted directly on the apparatus. Others had to be pulled and the prime mover (engine) or at least the boiler were hauled separately to the location. Horses or tractors, depending on the year and circumstances, were the hauling agents. Once set up at the site, these relatively small machines would drill the shallow oil wells to depths of 500 to 2500 feet (or even more) and run over 1800 feet of 17-20 lb. casing depending upon the capacity of the model. Depths of 1000 feet, usually less, handled most oil wells in the early oil belt of Oil Creek and its flanks. Some of the portable rigs drilled water wells as well as oil wells and were advertised for drilling "artesian" wells, a term which meant simply a "deep" well.

The mast is a necessary and very obvious element of a portable cable tool drilling machine and has remained so throughout the tenure of these machines, even their present-day counterparts. The mast took the place of the standard derrick which was built by carpenters at the earlier well sites. Raising the mast is one of the first jobs performed in setting up the rig. Early portable masts ranged from a gin pole (single pole with spikes for climbing) to the A-frame type which was a ladder narrowing upward. During transport the mast with its ever-present pulley would fold down over the rest of the rig.

Local inventions, "borrowed" parts, brainstorms that fitted one purpose but not another took place on the lease. All manner of modifications both subtle and pronounced have altered the appearance of some of these fossil drilling machines and spudders. A lot of them were eventually run by truck or car engines set up at a distance. Some were operated by engines using natural gas, deisel, even oil. These changes, many of which occurred at the well site, reappointed machines that were once operated by steam. Electric motors even crept into the scene. Newer models which incorporated the best of the improved technology are becoming old now and the manufacturing plants for some of them have shut down.

Oil Well Supply Co. advertised a gasoline-fueled drilling machine in their 1913 catalog (none were in the 1904 edition). National Supply Co. was still giving prominence to steam-driven drilling rigs in their 1921 catalog, and gasoline or other power sources were not mentioned for mounted cable tool drilling machines. However, National Supply in 1921 separately listed a four cylinder, four cycle Clark drilling engine (Olean, N.Y.) which could use gas, gasoline or California distillate. The ad stated that it was "an ideal power unit not only for drilling but for pulling tools and bailing as well". Apparently this engine could serve a standard rig, but it is questionable if it could be accommodated on board the portable cable tool rigs pictured by National at that time. Perhaps it was used in an off-rig position.

The author has parts of 1928 and 1935 Star bulletins showing gasoline engines mounted on the drilling machines. At least two models have crawler tracks and the power source is a built-in McCormick-Deering tractor. An Oil Well Supply Co. catalog of 1935 advertises Star water well drilling machines, truck-mounted and wagon-mounted with a gasoline motor. It is assumed that gasoline-powered rigs in general began to slightly rise in number in the years just prior to the Great War and that after the war, in the 1920's, the manufacture of steam-powered rigs declined to the eventual domination of gasoline and diesel.

The Most Powerful Diesel Engine in the World!

The Wartsila-Sulzer RTA96-C turbocharged two-stroke diesel engine is the most powerful and most efficient prime-mover in the world today. The Aioi Works of Japan's Diesel United, Ltd built the first engines and is where some of these pictures were taken.

It is available in 6 through 14 cylinder versions, all are inline engines. These engines were designed primarily for very large container ships. Ship owners like a single engine/single propeller design and the new generation of larger container ships needed a bigger engine to propel them.

The cylinder bore is just under 38" and the stroke is just over 98". Each cylinder displaces 111,143 cubic inches (1820 liters) and produces 7780 horsepower. Total displacement comes out to 1,556,002 cubic inches (25,480 liters) for the fourteen cylinder version.
Some facts on the 14 cylinder version:
Total engine weight: 2300 tons (The crankshaft alone weighs 300 tons.)
Length: 89 feet
Height: 44 feet
Maximum power: 108,920 hp at 102 rpm
Maximum torque: 5,608,312 lb/ft at 102rpm

Fuel consumption at maximum power is 0.278 lbs per hp per hour (Brake Specific Fuel Consumption). Fuel consumption at maximum economy is 0.260 lbs/hp/hour. At maximum economy the engine exceeds 50% thermal efficiency. That is, more than 50% of the energy in the fuel in converted to motion.
For comparison, most automotive and small aircraft engines have BSFC figures in the 0.40-0.60 lbs/hp/hr range and 25-30% thermal efficiency range.

Even at its most efficient power setting, the big 14 consumes 1,660 gallons of heavy fuel oil per hour.

The internals of this engine are a bit different than most automotive engines.
The top of the connecting rod is not attached directly to the piston. The top of the connecting rod attaches to a "crosshead" which rides in guide channels. A long piston rod then connects the crosshead to the piston.
I assume this is done so the the sideways forces produced by the connecting rod are absorbed by the crosshead and not by the piston. Those sideways forces are what makes the cylinders in an auto engine get oval-shaped over time.

The crank sitting in the block (also known as a "gondola-style" bedplate). This is a 10 cylinder version.
Note the steps by each crank throw that lead down into the crankcase:

background

High Power-Laser Cutter

High power CO2 laser cutting machines are applied in metal cutting and die-board wood cutting. Metal cutters are widely used in electrical switch manufacturing, machinery production, the auto industry, chemical industry, ship-building and so on. Die-board cutters are widely used in printing and packing. Both of these types of high power cutters have the advantage of precision manufacturing, flexible cutting,high speed and high efficiency.

The high power CO2 laser oscillator developed by Han’s Laser, is the only CO2 laser oscillator in the high power sector in China that adopts independent high voltage switch stimulating technology and axial fast flowing technology (1200W, 2000W, 2200W available).

My Laser Cutting Experiences

In the fall of 1996, I started getting interesting in marquetry, just as reason to build a CNC router. In February 1997 I started Inlay.com, with the hopes of learning more about marquetry, inlay, and mosaics in general. I built a homemade CNC router, it was neat, but its performance was lack luster. I almost took a job that involved programming a CNC waterjet, but that fell though; I was a bit greedy on my salary, live and learn! All along, people were telling me from time to time, to check out lasers to see how they can be used in the craft, but I just never looked into it.

In summer of 2000, I started work at a company that had a 50-watt laser engraving, cutting machine. In all honesty, the laser was one of the biggest job benefits. I actually started at the company, without seeing it first. Now I have to fill you in a little, I have been in many shops that have industrial lasers. The large industrial lasers are like 3000 watts, and can cut one inch (2.5CM) thick stainless steel. They have the ability to turn a full 1/2" (1.3CM) sheet of plywood into shreds, in minutes. This laser just does not have the gusto to pull a stunt like that off.
So this was part of my job, to program this machine, that I had never seen. I knew the company used it to cut out, and engrave plastic panels, and thick paper, but I still had the idea in my head of a truck-sized machine. This machine is about the size of a standup copier. The first time I seen it I was rather disappointed. That only lasted a few minutes. I was awed and memorized by the way it cut! It was a useful machine after all. With a CNC router, one has to hold down the material so it doesn't move while cutting. In a laser cutting machine if you follow a few simple rules, no hold-downs are required. You do have to worry about pieces moving after they are cut a little, but still this is much, much easier, then a rotary machine.
How it works is quite simple. In the back of the machine, there is a 50-watt CO2 laser tube. There are mirrors and lenses, which get the laser beam, to the yellow lens at point 1 in the picture below. At point 2 there is a right angle mirror, that redirects the beam to point 3. At point 3, there is another right angle mirror that points the beam downward. Along with the mirror, there is a lens that focuses the beam to point 4. The lens that I used had a two-inch focusing distance. You can see there are 3 screws at point 3; the right angle mirror, and lens assembly comes out for cleaning. I don't know why, but I was surprised that the laser beam was not enclosed in its travels. You can see from the top picture on this page, that the user is protected from the working compartment, by the top lid of the machine. The window is coated to protect the user's eyes from stray laser light.

The beam is moved around by 2 slides. The Y slide is the beam that is between point 2 and point Y. It travels on rollers at points 2 and Y. You can see these rollers at point Y. So this bar travels back and forth, from the front of the machine to the back. Gezz this sounds so dry and technical! Anyway, the lens assembly, or laser head, at point 3, is the X-axis. It travels from left to right, on rollers at point X. These two slides are move with cogged belts, which are moved with stepper motors.

The bed of the machine travels up and down on four lead screws. One of them can be seen at point Z. These four lead screws are powered by cogged belts that are all powered by one stepper motor. The reason the table moves up and down is so you can focus materials of different thicknesses. The bed of the machine will go down 8 inches, in case you had something 8 inches thick to be cut or engraved. This comes in handy if you wanted to engrave a trophy, or the back of your boom box.
