Product description
Dense castable refractory 1700c are mainly made of high-strength refractory raw materials such as special-grade alumina, corundum and silicon carbide as aggregates and fine powder, and added with micro powder. The material has the characteristics of good volume stability, high strength, good wear resistance, thermal shock resistance, corrosion resistance, no cracking, no peeling, etc.
Applications of dense castable refractory 1700c:
Refractory castables are used in various heating furnaces, soaking furnaces, circulating fluidized bed boilers, waste incinerators, waste heat power generation boilers, hot blast furnaces, continuous casting tundish, hot metal tanks and tapping troughs, etc.
