...Other steel bottlenecks: Continuous mills roll semi-finished steel into sheet and strip much faster than open hearth furnaces now operating feed them with ingots. Nor can the blast furnaces now in operation keep up with the open hearths. Steel making at Youngstown, Ohio dropped two points (to 80%) this week because of a shortage of iron. At Buffalo last week Bethlehem Steel blew in its old No. 2 blast furnace. One blast furnace, last relined in 1919, was put in service. Rush orders for refractory brick to reline steel and iron furnaces made Pittsburgh's Harbison-Walker Refractories...
...Conservative Winston Churchill has long been the cat that walked by himself when he was not clawing the Government for its haste to appease and its tardiness to arm. Like the sly puss in Kipling's Just So Stories, he has had to sit beyond the cozy Government hearth, destined never to warm a Cabinet corner unless somebody spoke him a kind word. Presumably because Winston Churchill is not only the Conservative Party's best brain but its most unpredictable personality, safe & sane Conservatives withheld their kind words until last week. Sly Puss Winston Churchill purred gratefully when...
...hearth and no fire...
Since 1920 steelmaking has had a big swing to the open-hearth process. These furnaces, lined with dolomite (lime and magnesia oxide), are primed with plate scrap and limestone, then charged with pig iron, scrap and ore, and heated. Gas expelled from the limestone stirs the mixture, helps form the slag. A furnaceman spoons out samples, cools them to test quality, then adjusts the heat to get just the quality he wants. After about twelve hours the furnace is tapped, the steel ladled off. The Bessemer process is three times faster than the open-hearth, and correspondingly cheaper; but since...
...fared thinly in recent years, had developed a photoelectric indicator ("robot eye") which, by judging the color and brilliance of a Bessemer heat better than human eyes can, made it possible to turn out steel with Bessemer rapidity but of a uniform quality comparable to that of the open-hearth product. The J. & L. researchers guarded their secret vigilantly, declared darkly not long ago that two other companies had tried to swipe...
