Refractory Castable

Refractory castable is a kind of granular and powdery material made of refractory materials and a certain amount of binding agent. It has high fluidity and is unshaped refractory formed by casting. Compared with other unshaped refractory materials, the binder and moisture content are higher, and the fluidity is better. Therefore, the castable has a wider range of applications. The materials and binders used can be selected according to the conditions of use. It can be directly poured into a lining body for use, and can also be used as a prefabricated block by pouring or vibrating method.

product details

Product Features:

Four advantages of Zhiyao refractory castables:
1.Refractory castables have the characteristics of low thermal conductivity, good thermal insulation performance, and good casting integrity.
2. The characteristics of refractory castables are to increase the medium temperature strength and load softening temperature, reduce the thermal conductivity, and have good thermal stability.
3. The air-tightness of refractory castables is also better than that of brick furnaces, which saves the cost of a furnace repair.
4. The ratio is reasonable to meet the customized needs of customers.
Lightweight refractory castables are hydraulic castables, suitable for all kinds of furnace lining heat insulation layer, float glass furnace flue sealing castables, with low thermal conductivity, good thermal insulation performance, small linear shrinkage, It has the characteristics of good pouring integrity and good drying strength. Heavy refractory castables are mainly used as lining and sealing materials for thermal equipment in industrial kilns. According to the performance of the binder, it can be divided into clay, high alumina, and inorganic refractory castables. They achieve their own performance characteristics under hydraulic and high-temperature conditions. Refractory castables have high acid resistance, corrosion resistance, thermal shock resistance, wear resistance, Anti-stripping, suitable for small and medium blast furnace hearths in cement kilns, power frequency induction electric furnace melting tanks, soaking furnace desulfurization hoods, blast furnace air duct rotary kilns and various flues, acids, tanks, and other parts.
