Curved Fire Brick Customized Size Refractory Firebricks For Sale

Curved firebrick is made from low mullite stones, the main mineral composition of the low mullite stones are pressed and sintered mullite phases. curved firebricks have very good physical and chemical properties in high temperature conditions. curved fire brick is widely used in the non-ferrous metal metallurgy, glass industry, ceramic kiln, cement rotary kiln, steelmaking furnace, chemical industry, construction industry and other industries.

Curved Firebrick Description

curved refractory brick contains Al2O3 about 30% ~ 45%, and silica content is lower than 78%. curved refractory bricks belong to the weak acid refractory materials. curved refractory block is resistant to acid slag and the erosion of acid gases, but the alkali resistance ability is a bit poor. curved refractory blocks have the characters of good thermal performance and good thermal shock resistance.
