...contributes to one of the most ingenious practices in modern arsenals-the centrifugal casting of gun barrels. Steel is induction-melted, then poured into a horizontally rotating mold which continues to spin until the casting hardens. Thus formed is a hollow, easy-to-bore barrel instead of the solid ingot from which cannon were formerly forged and drilled. Slag (formed by the oxidation of the molten metal) is forced to the inner surface of the casting, where it can easily be tooled away...
...make the final decision: whether to break Alcoa up. Three branches of law are involved: tariff law, patent law, the Sherman Act. The Government's charges were in twelve groups, for different branches of the industry: 1) bauxite; 2) water power; 3) alumina; 4) virgin aluminum, pig and ingot; 5) castings; 6) cooking utensils; 7) pistons; 8) extrusions and structural shapes; 9) foil; 10) miscellaneous fabricated articles; 11) sheet; 12) cables...
...largest steel ingot expansion in world history was approved by SPAB last week. The 10,000,000 new tons SPAB called for, added to some 3,000,000 now under construction, will bring the steel capacity of the U.S. to 99,267,468 tons, twice the entire capacity of Axis-controlled Europe and Japan. It will cost the U.S. Government $1,250,000,000, take at least two years to complete...
...instigation, 30 steel companies had submitted specific plans for expanding their plants in 15 States. Their plans kept the regional distribution of the U.S. steel plant about where it was before. One noteworthy change: the Pacific Coast, with 1,865,300 tons of new pig iron and steel ingot capacity projected, was to be made virtually self-sufficient...
...only must further expansion stretch back to the mine (requiring new mining and carrying equipment) but it must also soon include new rolling mills and other post-ingot equipment (requiring, among other things, thousands of motors). Experts believe that existing processing capacity can take care of perhaps 2,000,000 tons more of ingots-i.e., it probably could not even handle all the new ingot capacity now under...
