Magnesium-aluminium spinel bricks

Magnesium-aluminium spinel bricks is a high-grade alkaline refractory material with periclase and spinel as the main minerals, which is formed by high-pressure molding and high-temperature sintering. At the same time, special mineralizer is added to make the crystal phase particles of the products combine directly. It has the characteristics of high strength, excellent thermal shock stability and strong resistance to chemical erosion. It is mainly used in the upper and lower transition zone of cement rotary kiln and the kiln equipment requiring high temperature resistance and heat shock resistance.
