Product description
According to the type of cementing agent, furnace 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℃.
Advantages of furnace castable refractory
The type and dosage of clay binder have an important impact on its performance. The choice of soft clay binder requires good plasticity, strong dispersion, good adhesion, wide sintering temperature range, and high refractoriness.
