Introduction：
Refractory bricks for blast furnaces are refractory materials specially used for the inner lining of blast furnaces, and are mainly subjected to extreme working environments such as high temperature, chemical corrosion and mechanical shock. It is made of specially formulated refractory raw materials through molding, drying and sintering processes. The main components of refractory bricks for blast furnaces include high alumina aggregates, silicate aggregates and refractory cement. High-alumina aggregate is rich in high-purity bauxite or alumina, which has good fire resistance. Silicate aggregates consist primarily of silicate materials such as kaolin, which provide additional resistance to fire and erosion. Refractory cement is used to bond brick particles to increase its overall strength and stability; High refractory performance: Refractory bricks for blast furnaces can maintain good strength and stability at high temperatures, and withstand smelting reactions and impacts in high-temperature furnaces. Corrosion resistance: There are a large amount of metallurgical slag and acid gas in the blast furnace. The refractory bricks for blast furnaces have excellent corrosion resistance and can resist chemical erosion during the smelting process. Mechanical shock resistance: Refractory bricks for blast furnaces usually have high mechanical strength and compression resistance, and can withstand physical shock and vibration inside the blast furnace.
