Product description
According to the type of cementing agent, the conventional castable refractory can be divided into alumina cement refractory castables, aluminum-60 cement refractory castables, low calcium aluminate cement castables and pure calcium aluminate cement refractory castables. Aluminum salt cement refractory castables have the characteristics of rapid hardening, high strength, good thermal shock stability, and high refractoriness. Therefore, they are widely used in general industrial kilns and thermal equipment in metallurgy, petrochemicals, hydropower, building materials, machinery and other industrial sectors. On the market, its maximum operating temperature is 1400-100℃, and some can reach around 1800℃.
Applications of conventional castable refractory:
◆Cement kiln
◆Heating furnace
◆Recirculating fluidized bed boiler
◆Chemical industry and construction industry
◆Tundish lining
