☆ Magnesia iron spinel bricks ( perclase-hercynite refractory bricks) use high-purity magnesia and iron-aluminum spinel as the main raw materials, and the firing temperature and firing atmosphere are strictly controlled to make the product have good flexibility and thermal shock stability. The performance and corrosion resistance of the hanging kiln skin exceed those of high-quality magnesia-chrome bricks. This product is an updated product for the inner lining of large dry-process cement rotary kiln. Perclase-hercynite refractory brick is an alkaline refractory material with a magnesium oxide content of more than 90% and periclase as the main crystal phase.

☆ The good kiln skin hanging property of the product not only protects the kiln skin, but also protects the pre-homogenization of raw materials, slows down chemical erosion, and prolongs the service life of the rotary kiln.
