Iron-Alumina Spinel Bricks (MFA-)
Magnesia iron spinel brick is a new generation of large-scale rotary kiln firing zone with chromium-free alkaline refractory material. It utilizes high-purity spinel as raw material and iron-free sintering by high-temperature sintering. Environmentally friendly products, they can effectively solve the problem of causing pollution to the environment by generating hexavalent chromium during the use of magnesia chrome bricks for cement kiln.
