Material classification and application of corundum brick

Date:2020-03-27 11:35 From:Zhengzhou Sunrise Refractory Author:admin
The main materials of corundum brick are:
 
Brown corundum: Brown corundum bricks use bauxite and coke (anthracite) as the main raw materials.Smelted at 2000 ° C.
 
White corundum: White corundum brick is made of alumina powder and smelted at high temperature.
 
High alumina corundum: High alumina corundum bricks are smelted using high-quality aluminum bauxite as the main raw material and using a special process in a high-temperature electric furnace at 2500 ° C.
 
Zirconium corundum: High-alumina corundum bricks are smelted using high-quality bauxite as the main raw material and using a special process in a high-temperature electric furnace at 2500 ° C.
 
Single crystal corundum: Single crystal fused alumina (also known as 32A) Abrasive: Single crystal corundum is mainly based on bauxite Material, with appropriate amount of sulfide, smelted at high temperature. Microcrystalline corundum: Microcrystalline corundum is based on bauxite, which is obtained by high temperature melting and rapid cooling crystallization.
Uses of corundum brick
 
1.Abrasion tools: suitable for grinding high tensile metals, such as various general steels, malleable cast iron, hard bronze, etc.
Can also make brown corundum bricks, it is a high-grade refractory material
2. Advanced refractory and abrasive materials.
3. Precision casting sand, spraying materials, chemical catalysts, special ceramics.
4. Dry grinding and grinding of workpieces that are easy to deform and burn.
5. Various high-temperature kiln linings and kiln furniture in cracking, converting furnaces and metallurgical industries in the petrochemical and fertilizer industries.
