Product Introduction of Magnesium iron spinel brick
The magnesia-iron spinel brick is compounded with iron-aluminum spinel and adopts special production technology to ensure that Fe in the product exists in the form of Fe2+, so that the product has good adhesion to kiln skin, corrosion resistance and flexibility. Magnesium-iron spinel brick is an ideal chrome-free basic refractory material for cement rotary kiln firing zone.
