1.Description
Our supply range of high alumina bricks are useful in the construction of steel refining furnaces, glass tanks, ceramic kilns, enamel kilns and rotary cement kilns. The high alumina bricks comprise of a blend of alumina and ferrous content and their apparent porosity is 15 to 23%. They have high refractoriness and can sustain themselves easily even in high temperature. This is the reason why they are used as high temperature equipments in various industries. These high alumina bricks are highly resistant to corrosion due to metal fluid and oxidation.
2.Feature
1. High refractoriness.
2. Good spalling resistance and wear resistance.
3. Good corrosion resistance.
4. Good thermal shock resistance.
5. High mechanical strength.
6. High-temperature creep rate is low.
3.High alumina bricks Application:
High alumina brick is widely used for widely used in blast furnaces, hot bast stove,steel ladle lining, reheating furnace, cement kiln, tunnel kiln,boiler, coke oven, carbon furnace,glass kiln , steel smelting furnace and various kiln lining and thermotechnical equipment, etc.
