A METHOD FOR CASTING GRAIN-ORIENTED INGOTS CONSISTING ESSENTIALLY OF IRON CONTAINING UP TO ABOUT 5 PERCENT SILICON, COMPRISING THE STEPS OF SUPPORTING A GRAINORIENTED METAL SEED SLAB CORRESPONDING IN COMPOSITION TO THAT OF THE INGOT IN SPACED RELATIONSHIP TO A HEAT EXCHANGER, CASTING MOLTEN METAL UPON THE SURFACE OF THE SEED SLAB REMOTE FROM THE HEAT EXCHANGER, CAUSING THE SEED SLAB TO BECOME MOLTEN, CONDUCTING A PORTION OF THE MOLTEN METAL INTO THE SPACE BETWEEN THE SEEN SLAB AND THE HEAT EXCHANGER TO SUBSTANTIALLY FILL THE SPACE. EXTRACTING THE SUPERHEAT AND LATENT HEAT FROM THE METAL FILLING THE SPACE TO THEREBY FORM A BAND OF HIGH HEAT CONDUCTIVITY BETWEEN THE SEED SLAB AND THE HEAT EXCHANGER AND EXTRACTING HEAT FROM THE REMAINDER OF THE MOLTEN METAL THROUGH THE SEED SLAB BY MEANS OF THE HEAT EXCHANGER.
