company news about Many different types of refractory materials

There are many different types of refractory materials, usually divide according to the level of 

refractoriness ordinary refractory materials (1580 ~ 1770 ℃), high-grade refractory (1770 ~ 2000 ℃) 

and super refractory (2000 ℃ above); by chemical properties into acidic refractory materials, neutral 

and basic refractory materials. In addition, there are also used for special occasions of refractory. 

Now the definition of refractory materials, have not only depended on whether refractoriness above 

1580 ℃, and now refers to the current refractories used in metallurgy, petrochemical, cement, 

ceramics and other production equipment lined the inorganic non-metallic materials.
