Products Description

Silicon carbide brick is fired with silicon carbide as the main raw material and silicon oxide as the binder at a temperature controlled at about 1400℃. Silicon carbide brick is characterized by low expansion coefficient at high temperature, not easy to deformation, good thermal conductivity, heat shock and high temperature resistance. Even in high temperature long-term use will not soften, and acid, alkali resistant bedroom. Carbon products are widely used in high temperature furnace lining (furnace bottom, furnace cylinder, furnace body, etc.), melting of non-ferrous metal furnace lining.

Silicon carbide brick is a refractory material with fire resistance and wear resistance after high temperature firing. The volume density of silicon carbide brick is directly related to the properties of silicon carbide brick. In general, the larger the proportion of silicon carbide brick, the smaller the porosity, the greater the compressive strength, the better the resistance to erosion, the better the resistance to penetration, and the better the wear resistance.

Due to stable chemical properties, high thermal conductivity, small thermal expansion coefficient, good wear resistance, in addition to abrasive, there are many other uses, such as: with a special process of silicon carbide powder coated in the inner wall of the turbine impeller or cylinder body, can improve its wear resistance and extend the service life of 1 ~ 2 times; Used to make the first refractory material, shock resistance, small size, light weight and high strength, good energy saving effect. Low grade silicon carbide (containing SiC about 85%) is a good deoxidizer, with it can speed up the speed of steel, and easy to control the chemical composition, improve the quality of steel. In addition, silicon carbide is also widely used in the production of electric heating element silicon carbon rod.

The product uses silicon carbide Mohs hardness 9. More stable for acid slag. The content of SiC is 72%-99%. Divided into clay bonded, Si3N4 bonded, Sialon bonded, β-SiC bonded, Si2ON2 bonded and recrystallized silicon carbide bricks. Mainly used for retort of nonferrous metallurgy, casting aluminum mold, electric furnace lining and heat exchanger.

Products Advantages

The main characteristics of silicon carbide brick are high temperature resistance, corrosion resistance, thermal stability and oxidation resistance, as well as good wear resistance and strength. At extremely high temperatures, silicon carbide bricks have good thermal stability and can maintain structural integrity for a long time.

Silicon carbide bricks have very high hardness and are relatively wear-resistant. At the same time, they can maintain high strength at high temperatures.

Silicon carbide bricks also have good thermal conductivity, so in the industrial production process, they can effectively conduct heat energy and improve production efficiency.

Silicon carbide bricks also have good vacuum tolerance and radiation resistance. In fields such as space exploration, silicon carbide bricks can well resist high-temperature radiation in vacuum environments.

Products Applications

First of all, silicon carbide bricks are widely used in the metallurgical industry, such as linings in high-temperature environments such as smelting furnaces, heating furnaces, and converters. The high temperature stability and wear resistance of silicon carbide bricks can effectively prevent corrosion and damage of the furnace wall and improve the working efficiency of the furnace.

Secondly, silicon carbide bricks are also widely used in the construction industry. As a refractory material, silicon carbide bricks can be used as heat and sound insulation materials in high temperature environments, and can also be used as building decoration materials. In construction projects, such as high-rise buildings, large commercial centers, etc., silicon carbide bricks can provide good safety protection.

In addition, silicon carbide bricks are also widely used in chemical industry, electric power and other industries. Silicon carbide bricks can be used for the lining of furnaces, kilns and high-temperature pipelines to improve the service life and safety of equipment; they can also be used to manufacture high-temperature resistant components such as high-temperature furnace materials, high-temperature filters and ceramic brackets.
