Wear resistant refractory castable

Ceramic wear-resistant castable is made of high-strength wear-resistant aggregate and ultra-fine powder. The selected refractory raw materials have super wear resistance. Generally, the common refractory raw materials with wear resistance include silicon carbide, brown corundum, steel fiber, etc. the fusion of refractory aggregate and powder makes the ceramic wear-resistant material have erosion resistance and can resist the erosion of molten slag and gas according to the principle of the closest accumulation.

In addition to strong wear resistance, ceramic wear-resistant materials also have the characteristics of high strength and high temperature resistance. They have strong scouring ability in high temperature environment and good wear resistance in medium and low temperature environment.

Ceramic wear-resistant castable are widely used in blast furnace sintering silo, flue, hot blast furnace pipeline, etc. the temperature in the environment where ceramic wear-resistant castables are generally used will not be too high, but they also need to have certain high temperature resistance. Ceramic wear-resistant castables need rapid lining performance in medium and low temperature environment to meet the needs of construction position and construction condition.

Ceramic wear-resistant castables are generally formed by pumping. This construction method requires mold installation at the construction site in advance. After the construction is completed, multiple construction processes such as curing and baking are also required to ensure the usability of ceramic wear-resistant castables; Ceramic wear-resistant spray coating is sprayed by spraying machine. This construction method requires the installation of steel structure connecting components at the construction site before construction. The spray material can be better attached to the construction site to ensure better lining of wear-resistant spray coating.
