Brief Introduction
Refractory cement is a special cement that can maintain its strength and hardness in high temperature environments. It is mainly made of a mixture of materials such as alumina and silicate. It has the characteristics of high strength, high wear resistance, high fire resistance and chemical corrosion resistance. The refractoriness of refractory cement is not less than 1580 degrees Celsius and can remain stable for a long time in high temperature environments.
We produces refractory cement、refractory castables、other refarctory materials. Welcome to contact us for wholesale price and more information!

Application Of Refractory Cement
1. It is particularly suitable for furnace shells, high-temperature pipes, blast furnaces, electric furnaces, and high-temperature environments such as steel plants and aluminum plants.
2. In the chemical industry, it is widely used for corrosion-resistant linings of equipment and pipelines in fertilizer plants, refineries, chemical plants, etc.
3. It is the main raw material for the production of various refractory castables, refractory bricks and other refractory materials.
