High-aluminum cement, also known as high-aluminum refractory cement or special cement, is a refractory high-aluminum product made from aluminate, slaked lime, and silicate as the main raw materials, with an appropriate amount of scorched earth and iron oxide and other admixtures added. cement. High alumina cement used in the refractory industry is a cement with high strength, high temperature, high wear resistance, corrosion resistance and good chemical stability. It is mainly used for the production of industrial buildings in harsh environments such as high temperature, high pressure, and corrosion.

1. High fire resistance: High alumina cement has extremely high temperature resistance and fire resistance, and can generally withstand high temperatures above 1500 degree . Therefore, it is widely used in industrial buildings such as stoves, metallurgical furnaces, glass furnaces, aluminum electrolytic cells, and blast furnaces.

2. High strength and hardness: High alumina cement has extremely high hardness and strength, and has good compressive and flexural strength. Therefore, it is widely used in the production of blast furnaces, metallurgical furnaces, converters, gas well linings, cement rotary furnaces and other buildings.

3. Good chemical stability: High alumina cement has good chemical stability and can resist acid and alkali corrosion and erosion. It has outstanding results when making buildings in highly corrosive environments such as chemical furnaces and steel smelting furnaces.
