Ingot casting - with addition of metal carbonyl - contg reducing or inert gases before solidification

Carbonyl-contg. inert or reducing gasses are used to treat melts on casting and/or during cooling before solidification, in ingot, esp. Fe or steel prodn. Process is suitable for continuous casting. Fe-, Cr-, Ni-, W- or Mo carbonyls are pref. used. Pref. Fe-, opt. mixed with Cr-, Ni-, W- or Mo carbo...

description Carbonyl-contg. inert or reducing gasses are used to treat melts on casting and/or during cooling before solidification, in ingot, esp. Fe or steel prodn. Process is suitable for continuous casting. Fe-, Cr-, Ni-, W- or Mo carbonyls are pref. used. Pref. Fe-, opt. mixed with Cr-, Ni-, W- or Mo carbonyl, is used for steel or Fe melts. Pref. carbonyl-charged gas is led intermittently to melt, partic. at foot of ingot mould, to ensure more even distribution of gases. Resulting ingots have fine grain-structure.
