Product Description
High Alumina Refractory Alumina Silica Brick Sk32 Sk34 Sk36 Sk38
Refractory bricks are mainly made from chamotte, flint clay and combining clay powder, being high pressure pressed and sintered in high temperature.
Low porosity bricks are made from low mullite stones, the main mineral composition of the low mullite stones are pressed and sintered mullite phases. The bricks have very good physical and chemical properties in high temperature conditions.
Refractory brick Features and advantages:
1.High refractoriness,
2.High-temperature endurable.
3.Good corrosion resistance.
4.Good spalling resistance and wear resistance.
5.Good thermal shock resistance.
6.High mechanical strength.
7.High-temperature creep rate is low.
8.Good volume stability at high temperature.
