Abstract

Possibility of reduction of the silicon content in ZhS32-VI alloy by combined intro-duction of AEE and REE additions followed by filtration of the melt through the ceramic foam filter with activated working surface from CaO. It was established that filtration rate influences the completeness of removal of nonmetallic inclusions from the melt. The effective use of yttrium for Ni-base melt refining from silicon impurity was demonstrated.
