Product introduction of silicon carbide brick
Silicon carbide brick is a kind of refractory brick with SiC as the main component, which is fired with industrial SiC as the raw material. The characteristics are. It has high strength, large thermal conductivity, small linear expansion coefficient, good thermal shock resistance, high temperature resistance and wear resistance, and strong chemical corrosion resistance under normal and high temperatures.
Characteristics of silicon carbide bricks.
Silicon carbide brick has high strength at room temperature and high temperature, large thermal conductivity, small linear expansion coefficient, good thermal shock resistance, high temperature resistance and abrasion resistance, and strong chemical corrosion resistance.
Application areas of silicon carbide bricks.
It is widely used in iron and steel, nonferrous metallurgy, ceramics, chemical industry, electric power and aerospace industry.
Various brick types supporting customized silicon carbide bricks can be customized and processed according to drawings.
