☆ 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.
☆ Low ASR, strong alkali resistance, strong resistance to alkali salt penetration, chromium-free and low iron, can effectively solve the common chemical damage of cement kilns, ensure the efficient and safe operation of cement kilns, and achieve the purpose of saving energy, reducing consumption and saving costs.
☆ The operation period of the products in various large, medium and small cement rotary kilns is more than 12 months. The 10,000-ton line of Huaxin Cement ( Huangshi ) Co. uses magnesia-iron spinel bricks. The first cycle runs safely for 410 days, and the second cycle runs safely. 414 days, the third cycle is running.
