More Information
Summary:A hypereutectic alusil alloy modified refining agent consists of Cu, Ti, La, Ce, Nd, Pr, P, C, B and Al. It processes hypereutectic alusil alloy smelt with inactive gas blowing mixing, makes eutectic silicon of hypereutectic alusil alloy modify, and make primary crystal silicon modify with size below 25mum. It is a green, long-effective and composite hypereutectic alusil alloy modified refining agent.
