What is the difference between mid-range magnesia and heavy burnt magnesia

Mid-range magnesia is the main raw material chosen is 92% magnesium oxide, which is pressed into balls by a ball press machine. 97 The ball shape of the pressed fused magnesia is 30mm, and the 30mm magnesia ball is calcined in a high temperature oil shaft kiln or coke shaft kiln. Light burned magnesia

The calcined product is called mid-grade magnesia, which is mainly used to produce high-grade alkaline shaped or unshaped refractories, and its finished products are mainly used in metallurgy, building materials, non-ferrous metals, chemical industries and other industries. In addition, the middle-grade magnesia is used to make metallurgical powders in the metallurgical aspect to join the furnace bottom and the furnace wall, and to make the slurry spraying furnace lining: manufacturing magnesia bricks and magnesia chrome bricks; It is also widely used in non-ferrous metal converting furnaces and rotary furnaces.
