Application of Dense Refractory Bricks

Because of its high density, low porosity and excellent high temperature performance, dense refractory bricks have been widely used in various industrial high temperature environments. The following are its main application fields:

I. Iron and steel industry

Dense refractory bricks are mainly used for lining of blast furnace, hot blast stove, ladle, hot metal ladle and other equipment in iron and steel industry. These parts need to withstand the erosion and mechanical impact of high-temperature molten metal, and the high wear resistance and erosion resistance of dense refractory bricks make them an ideal material.

II. Glass industry

In glass furnaces, dense refractory bricks are often used in the parts of the melting part, such as the pool wall, the pool bottom and the main passage, which are in contact with high-temperature glass liquid. For example, dense chrome oxide brick is widely used in E glass unit kiln because of its excellent corrosion resistance. In addition, dense zircon bricks are also commonly used in the bottom and key parts of glass tank kilns.

III. Cement industry

Dense refractory bricks are used in cement kiln lining, vault and other parts, which can withstand high temperature and chemical erosion in cement production. Its high refractoriness and low creep performance make it perform well in the high temperature environment of cement kiln.

IV. Non-ferrous metal industry

In the process of smelting and refining nonferrous metals, dense refractory bricks are used in furnace lining, molten pool and other parts to prevent the penetration of molten metal and the corrosion of furnace body. Its high fire resistance and corrosion resistance make it stable in complex chemical environment.

V. Other high-temperature industrial equipment

Dense refractory bricks are also widely used in other high-temperature industrial equipment, such as coke ovens, boilers and garbage incinerators. In these equipments, dense refractory bricks are used in furnace lining, combustion chamber and other parts to improve the thermal efficiency and service life of the equipment.

VI. Special applications

High temperature induction furnace: dense refractory bricks can be used for lining of high temperature induction furnace because they can withstand high temperature and mechanical stress.

Key parts of glass kiln, such as launder brick and thermocouple brick, etc. The high compactness and corrosion resistance of dense refractory brick make it an ideal material for these parts.

Dense firebrick plays an important role in high temperature industry because of its excellent performance, which can effectively prolong the service life of equipment and reduce maintenance costs.
