Magnesium iron spinel bricks are a new generation of chromium-free alkaline refractory materials used in the firing zone of large rotary kilns. They utilize the characteristic of iron oxide solidifying in magnesium oxide, using high-purity spinel as raw material, and are formed into chromium-free and environmentally friendly products through high-temperature sintering.
