ROLE OF Ti₂O IN MOLD POWDER

Li₂O was added to two base powder with different glassy properties so as to study the effect of Li₂O on the viscosity, melting temperature and glassy property of mold powder.The mechanism how the glassy property of mold powder is improved by Li₂O was investigated,and an approach was proposed to choose an substitute for Li₂O used in the mold powder for high speed continuous casting.
