Prior to the decarburization step, one more step should be taken into consideration: de-siliconization, which is a very important factor for refractory lining and further refinement. The decarburization step is controlled by ratios of oxygen to argon or nitrogen to remove the carbon from the metal bath. The ratios can be done in any number of ...
Electrical steel is one material that uses decarburization in its production. To prevent the atmospheric gases from reacting with the metal itself, electrical steel is annealed in an atmosphere of nitrogen, hydrogen, and water vapor, where oxidation of the iron is specifically prevented by the proportions of hydrogen and water vapor so that the only reacting substance is carbon being oxidized ...
The Wargames Research Group (WRG) is a British publisher of rules and reference material for miniature wargaming.Founded in 1969 they were the premier publisher of tabletop rules during the seventies and eighties, publishing rules for periods ranging from ancient times to modern armoured warfare, and reference books which are still considered standard works for amateur researchers and wargamers.
These techniques prevent the compounds from reacting with components of air, usually water and oxygen; less commonly carbon dioxide and nitrogen. A common theme among these techniques is the use of a fine (10 0 –10 −3 Torr) or high (10 −3 –10 −6 Torr) vacuum to remove air, and the use of an inert gas: preferably argon, but often nitrogen.
2 * where the positive charge is moved from the carbon dioxide part to the argon. This molecule may occur in the upper atmosphere. Experimentally the molecule is made from a low-pressure argon gas with 0.1% carbon dioxide, irradiated by a 150 V electron beam. Argon is ionized, and can transfer the charge to a carbon dioxide molecule. [36]
War Games Rules 1950–2000: Wargames Rules for All Arms Land Warfare from Platoon to Battalion Level A computer-moderated adaptation of the 1988 edition was created by WargameSystems. [ 3 ] This is claimed to preserve the WRG rules structure and key data while the software automates the mechanics of playing by these rules, hence saving time ...
A reducing atmosphere is an atmosphere in which oxidation is prevented by absence of oxygen and other oxidizing gases or vapours, and which may contain actively reductant gases such as hydrogen, carbon monoxide, methane and hydrogen sulfide that would be readily oxidized to remove any free oxygen.
He rated "Shiloh" a C, noting that "The chief defects of this game are those of the quads as a whole, particularly the attack effectiveness rules." He rated "Antietam" a relatively good B−, and "Chickamauga" a B+, calling it "Easily the best of the B&Gs, this has become a perennial convention tournament favorite, mainly because it is exciting ...
