Product Description

High aluminum brick is made of high aluminum vanadium soil with a certain amount of clay combined with aluminum content from 46% to 80% of aluminum silicon series refractory brick, has excellent compressive strength and anti-spalling performance, while high aluminum brick is a neutral resistant material product, so the slag resistance and acid and alkali corrosion resistance is particularly outstanding. It can be used in non-metal smelting furnace, ladle, cement rotary kiln, lime kiln, waste incinerator, heating furnace and other industrial furnaces.

Features Of High Alumina Brick

It has good high temperature fire resistance
High temperature resistance, good fire resistance
Low impurity content
Good thermal shock resistance
Excellent resistance to slag wear
Good cold pressing strength

Applications Of High Alumina Brick

Nonferrous Metal Furnace
Rotary & Shaft Kiln
Various Incinerator
Reheating Furnace
Permanent Lining For EAF Ladle
General Industrial Furnace etc.
