company news about Some performance of refractoriness of refractory bricks

Refractoriness of the refractory bricks resistance refers to high temperature in no load and performance without melting. The significance of refractoriness and the melting point is different. Can't use the refractoriness as the temperature of the refractory brick. The basic factor that determines the degree of refractoriness is the chemical composition and distribution of refractory materials. All kinds of impurity, especially the impurities with strong flux effect, it would seriously reduce the refractoriness of the products.
