Magnesium Iron Spinel Brick
Magnesium Iron Spinel Brick
Magnesia iron spinel brick is an excellent product of a “chrome-free” cement kiln firing zone. It has excellent kiln skin hanging ability, good thermal shock stability, cement clinker erosion resistance, and a low thermal expansion rate. It has an excellent application effect in cement kiln firing zones.
Description for Magnesium Iron Spinel Brick for sales
Magnesia-iron-spinel bricks use high-purity magnesia and aluminum-iron spinel as the main raw materials and are formed through proportioning and high pressure. The firing temperature and time must be strictly controlled during the production process.
