Low silicon and high calcium fused magnesia products are mainly made of low silicon magnesite as raw material by high temperature electric melting furnace. Calcium is twice that of silicon, the grain is fully developed, and the bulk density is also large. Low silicon and high calcium fused magnesia is mainly used as a good raw material for medium frequency induction furnace melting, high manganese steel, stainless steel, high caustic steel, advanced alkaline bricks, carbon products and amorphous refractories.
