Abstract : The work covers the details of production methods used in producing eight cast steel plates 48 in. x 60 in. x 5 in. and 6 in. thick. Steel for this work is a Cr - Mo composition of .28% C; 2.50% Cr; .5% Mo. Casting technique for the rapid unidirectionally solidified section employed a 48 in. x 60 in. x 7 in. thickness cast iron chill in the drag with a 48 in. x 60 in. x 3 in. thickness exothermic core on the cope surface. The plates were water quenched and tempered to a hardness level of 320 - 370 BHN. Foundry procedure, heat treatment, and production processing are reported in detail. Physical test values of tensile and impact properties and the radiographic inspection results are reported. (Author)
