The silicon carbide product is a refractory material produced by using different binders as the main raw material of silicon carbide sand. It has high thermal conductivity, low expansion coefficient, good thermal stability, high temperature withstand voltage, high flexural strength and stable chemical properties. Widely used in iron and steel metallurgy, chemical, ceramic and other industrial furnaces and anti-corrosion wear-resistant pumps and pipeline lining.

Silicon carbide sand is made from silica and carbonaceous raw materials in an electric furnace at a high temperature, while silicon carbide products are made of silicon carbide sand as an aggregate, and oxide, silicate or silicon powder is used as a high-temperature bonding material. It is formed and fired.

The special properties of silicon carbide refractories determine that it can be used in different conditions and in different industrial fields. Due to its high thermal conductivity, silicon carbide refractories are widely used in the manufacture of muffle furnaces, heated hearths and heat exchangers, crucibles, carburizing tanks, thermowells, closed-end temperature measuring tubes and large bricks. Silicon carbide products are also used in many non-direct heating furnace structures, such as zinc distillation columns, vertical and horizontal distillation tanks. The SiC refractory has a high mechanical strength and wear resistance over a wide temperature range, so it can be used to make mechanically wear-resistant parts, including low-temperature guide rails and tie rods, as well as strongly worn spins. The lining of the divider, the dust collector, the pipe, the chute, the bottom of the furnace, the lattice plate of the tunnel kiln car, the porous product for the filter gas, and the like. The special chemical properties of silicon carbide refractories make it very effective in various furnaces and plants in the non-ferrous metallurgical and chemical industries. Silicon carbide refractories are also used in steam boilers.
