Brief introduction and Application:
High alumina brick is a neutral refractory material. It has certain corrosion resistance to acidic and alkalinity, has high compressive strength, erosion resistance, strong permeability resistance and high load softening starting temperature. It is widely used for iron and steel making industry, nonferrous Metal industry, building materials industry, energy and incineration industry, etc.
Technical data:

Advantages:
High-grade refractory materials:
Higher refractoriness than clay bricks and semi-silica bricks, up to 1790℃.
Refractoriness under load:
Due to its high Al2O3 content with low impurity content, and a low formation of the molten glass body, the fire-resistant softening temperature is higher than refractory clay brick.
Slag resistance:
High alumina brick is close to neutral refractory material, can resist the erosion of acid slag and alkali slag.
Packing and delivery details:
