Abstract :
IN THE competitive struggle of steel manufacture, the modern tendency is toward the adoption of bigger, faster, and more efficient machinery. In point of size, a new 98-inch strip mill recently placed in service by the Republic Steel Corporation at Cleveland, Ohio, now dominates the field. Recent improvements in lubrication, hydraulics, welding, design of bearings, and electrical control have been embodied in the design of the new mill to make possible the production of extra-wide sheet steel at an exceptionally high speed. Maximum delivery speed of the hot mill is 2,121 feet per minute. It can roll all finished widths from 30 to 94 inches and all finished thicknesses from 18-gauge strip to one-half-inch plate. The plant has a rated capacity of 70,000 gross tons per month.
