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.
Properties of Curved Firebrick
.High refractoriness,
.Good corrosion resistance,
Good thermal shock resistance,
.High mechanical strength,
.High-temperature creep rate is low,
.Good spalling resistance and wear resistance.
