Silicon slag is a subsidiary product of metal silicon smelting, the silicon content is generally 30-70%.
Silicon slag use: Silicon slag can be used for recrystallization and purification in the middle; effective slag discharge, increase the label, improve the toughness of the casting and the cutting ability And output.

1.It’s a good substitute for ferro silicon in steel making which has advantage in reducing the making cost.
2.The silicon slag powder can be made silicon briquette which has far and wide market at home and abroad.
3.It is used as deoxidizer in steel making.
