METHOD FOR MAKING SEMI-PRODUCT FOR METALLURGICAL CONVERSION Russian patent published in 1995 - IPC

Abstract RU 2039090 C1

FIELD: ferrous metallurgy. SUBSTANCE: method for making semi-product for metallurgical conversion includes preliminary filling mold of casting machine with solid additions followed by casting liquid metal above them. A substance in added in working volume of the mold. The substance evacuates gas at the temperature less than one of the metal being cast. The metal is amounted for 0.1 5.0 per cent of substance weight. The mold is filled with liquid metal for 30 70 per cent of its working volume. EFFECT: semi-products of higher strength, of decreased metal fraction. 2 cl
