THERMAL CAR COVERS WITH CERAMIC FIBER LINING IMPROVE CONTROL AND OUTPUT OF STEEL AT REPUBLIC MILL

Covered flatbed rail cars, resembling Quonset huts on wheels, have helped Republic Steel's Primary Mill in Chicago increase output, improve scheduling and enhance metallurgical properties. The insulated cars, replace burial pits for slow cooling unfinished steel in a controlled environment. The covers consist of a relatively thin steel outer shell lined with ceramic fiber blanket. These covered cars give such fine cooling control that billet rejection due to flaking and splitting is reduced by 30% or more, and not as many heats are lost. The cooling rate is about 20 deg F per hour, or from 1600 deg F to 600 deg F over a 48-hr period.
