Product Description
Alumina content more than 90%, is given priority to with corundum crystal phase of refractory products. High room temperature compressive strength (up to 340 mpa). High rul start temperature (greater than 1700 ℃). Good chemical stability, acid or alkaline slag, metal and glass, etc. Have strong ability of resist. Thermal shock stability is related to its organizational structure, the erosion resistance of dense products is good, but poor thermal shock resistance.
Divided into sintered corundum brick and fused corundum brick two kinds. Respectively using sintering alumina and fused corundum as raw materials or Al2O3 / SiO2 than high bauxite clinker and sintered alumina, made by sintering process. Also can use phosphoric acid or other adhesives made don't burn corundum brick.

Features
1.Load softening temperature greater than 1700℃.
2.Good chemical stability compression strength.
3.The slag resistance strong also can resist glass solution.
4.Good thermal shock stability and erosion resistance.
5. High compression strength.
6.High temperature creep rate is low and small thermal expansion coefficient.
Applications
Corundum brick is mainly used for blast furnace and blast furnace hot blast stove, furnace refining furnace, sliding water apparatus, glass furnace, and petrochemical industrial furnaces, etc. Also widely used in petrochemical and chemical fertilizer industry of cracking, such as high temperature transformation furnace, metallurgical furnace lining, and kiln furniture.
Application for corundum brick
Product manufacture
Each piece of high quality refractory bricks are from raw material to start .Clay refractory brick is a clay as the main raw material, through mud processing, molding, drying and roasting and. And then through the detection of detection equipment, to ensure that the quality of each brick, which is a batch of refractory brick process.
