Characteristics of low porosity clay brick:
High load softening temperature, excellent thermal shock resistance, good volume stability, low porosity, good mechanical strength, good wear resistance, permeability resistance, acid resistance and slag corrosion resistance.
Application:
Low porosity clay brick is widely used in large blast furnace matching hot blast furnace, mainly used in the middle and lower cell of hot blast furnace regenerator, support arch and so on. In addition, lime kiln high temperature belt, glass kiln regenerator and other high temperature industrial kilns.
Company main products and profile:
Our total annual production capacity is about 100,000 tons of dense-shaped refractory product, and 100,000 tons of monolithic refractory product.
We have three tunnel kilns for silicon-aluminum dense bricks and one new plant for the monolithic refractory.
We're sure our custom-made products and professional services will bring you a stable quality supply and more profit.
