Dead-burned magnesite
產品參數
Natural magnesite ore is used and calcined in high temperature shaft kiln. The content of product is mainly divided into 80%, 85%, 90%, 91%, 92% and 93% of magnesium content. The hydrating ability of re calcined magnesite is strong. It is mainly used as raw materials for making bricks and indefinite refractories. The finished products are used for steelmaking, circuit furnace bottom and ramming furnace lining.
