High strength: Low-cement castables increase the amount of fine aggregate and ultrafine powder. This improves the density and strength of the material.
Strong corrosion resistance: This castable refractory reduces the content of alkaline materials. It can resist the chemical erosion of acidic and alkaline slags.
High refractoriness: Low-cement castables use refractory materials. This improves the refractoriness by more than 100-200 degrees Celsius.
Good thermal shock resistance: The low-cement ratio is optimized, and the thermal expansion coefficient is low. It can stably resist thermal shock.
Good building performance: Low-cement castables have good flowability. It can be used as a filler for any shape. It is very convenient for construction.

Metallurgical industry: Low-cement castables are used in blast furnaces, hot blast stoves, electric furnaces, open hearth furnaces, converters, melting furnaces, and sintering furnaces. They are mainly used for furnace linings. They can help improve the production efficiency of the kiln.
Building materials industry: Low-cement castables are used in cement kilns, glass kilns, ceramic kilns, and refractory kilns. They are mainly used for linings. It is the key guarantee for the production of building materials.
Chemical industry: Low-cement castables are used in chemical furnaces, reactors, pipelines, and burners.
Power industry: Low-cement castables are used in boilers, turbines, flues, and dust collectors.
