lt is made of high quality iron-rich magnesia and spinel, combined with advancedtechnology and sintering at high temperature.Since the iron in the high-iron magnesia issolute in the periclase, the presence of appropriate amount of iron strengthens thecompatibility between the refractory brick and the cement clinker, and improves theadhesive strength.On the other hand, the presence of Fe2+,continuous diffusion occursin the high temperature environment, and this diffusion promotes the mutual diffusion ofMg2+ and Al3+.Thus, a series of reactions will occur to generate Fe-Al spinel and MFe-Alcomposite spinel.The presence of this spinel improves the chemical corrosion resistanceof the material.Meanwhile, this continuous diffusion plays a role in activating the crystalstructure at high temperature, increasing the thermal shock resistance stability of firebrick,and improving the service cycle of firebrick.Use the parts: 2500T/d—5000T/drotary kiln burning zone
