Magnesium iron spinel bricks are mainly made of high-purity magnesia sand and iron aluminum spinel, and the firing temperature and atmosphere are strictly controlled to make the product have good flexibility and thermal shock stability. The performance and corrosion resistance of the kiln coating exceed that of high-quality magnesia chrome bricks. This product is an updated version of the lining for large-scale dry process cement rotary kilns. The difference between magnesium iron spinel brick and magnesium iron aluminum spinel brick lies in the presence or absence of aluminum element. Aluminum element is widely used in alloys and other fields, and is relatively lighter in weight and stronger, making it better.
