METHOD FOR ALLOYING WORKING SURFACE OF STEEL INGOT MOLD Russian patent published in 2002 - IPC

Abstract RU 2192939 C2

FIELD: foundry. SUBSTANCE: method comprises steps of making rod of liquid self-hardening mixture; applying onto it pickup-proof paint; drying rod; heating ready rod up to 60-100 C; applying onto it paint containing, %: cryolite, 2-2; fire clay, 10-20; sodium chloride in relation with cryolite, 0.7-1.0; powdered aluminium, the balance. Paint density, 1.6-1.8 g/cu.cm; consumption of paint consists 1200-2000 g/sq.cm. Said relation of cryolite and sodium chloride prevents pickup of ingot mold. EFFECT: enhanced operational strength of ingot molds.
