The thermal equipment in the petrochemical power industry is of various types and has complex structures and shapes. In view of the above situation, it is more appropriate for the petrochemical power industry to use various amorphous refractory materials and various special refractory materials as linings.
Commonly used refractory materials include various light and heavy refractory bricks and a series of light and heavy refractory castables, ramming materials and plastics. The materials include corundum, high alumina, silicon carbide and magnesium chromium.
Below we will introduce the performance characteristics and applications of heavy refractory bricks
Heavy refractory bricks are a type of refractory material characterized by high density and high strength, usually made from high-alumina bauxite, silica or magnesia raw materials sintered at high temperatures. Its main performance characteristics include:
High refractoriness: able to withstand long-term use in high temperature environments.
Excellent compressive strength: suitable for kiln structures subject to mechanical loads.
Good slag erosion resistance, able to resist erosion by molten metal, slag and chemical gases.
Low porosity: reduces heat penetration and chemical erosion.
High thermal conductivity: suitable for industrial furnace environments requiring uniform heat dissipation.
Industrial furnace application scenarios
Heavy refractory bricks are widely used in key parts of high-temperature industrial furnaces:
Steel metallurgy: blast furnace hearth, hot blast furnace vault, converter lining, need to withstand molten iron scouring and alkaline slag erosion.
Glass industry: glass melting furnace pool wall and flow hole, rely on its resistance to glass liquid erosion.
Cement industry: rotary kiln firing zone and transition zone, withstand clinker wear and high-temperature chemical corrosion.
Chemical kilns: such as coke oven carbonization chamber, need to take into account high thermal conductivity and structural stability.
As the core material of high-temperature industrial furnaces, heavy refractory bricks play an irreplaceable role in metallurgy, cement, chemical industry and other fields with their excellent performance. In the future, with the advancement of industrial technology, the formula and process of heavy refractory bricks will continue to be optimized to provide more reliable solutions for more stringent high-temperature environments and promote the sustainable development of industrial production.
