Description
Advantage:
a.High-alumina bricks have a high refractoriness, up to 1750 ~ 1790 ℃, which is a high-performance refractory material. Generally, refractory bricks with higher alumina content have better fire resistance.
b. High load softening temperature
c. Very good thermal conductivity
d. Better thermal shock stability
e. Excellent resistance to acid and alkaline slag
f. Long using life
