Product Details

Competitive price corundum brick for refining furnace in steelmaking industry

Product Description

 

Corundum bricks for refining furnace in steelmaking industry refer to refractory products with alumina content higher than 90% and corundum as the main crystal phase. Very high normal temperature compressive strength (up to 340MPa).

 
High load softening start temperature (more than 1700°C). Very good chemical stability, strong resistance to acidic or alkaline slag, metal and glass liquid. Thermal shock stability is related to its structure. The corrosion resistance of compact products is good, but thermal shock stability is poor.
 
Specification

Competitive price corundum brick for refining furnace in steelmaking industry

Corundum brick Features: Alumina content is higher than 90%. High compressive strength at room temperature (up to 340MPa). High load softening starting temperature (greater than 1700 ℃). Good chemical stability, strong resistance to acidic or basic slag, metal and glass fluid, etc.

Sintered Corundum brick is a refractory material with alumina content higher than 90% and often containing trace impurity elements Cr, Ti, Fe, and V. The corundum bricks on the market can also be divided into these types according to the composition:  
1. Brown corundum bricks are made of bauxite and coke (anthracite) as the main raw materials. The main chemical components are alumina. The titanium oxide ring contains a small amount of silicon oxide and iron oxide. 
2. High-alumina corundum bricks are made of high-quality bauxite as the main raw material, and sub-white corundum bricks are produced on the basis of high-quality brown corundum bricks. Because its chemical composition and physical properties are similar to white corundum, subwhite corundum is produced on the basis of high-quality brown corundum.
3. White corundum bricks are made by high temperature smelting with alumina powder as raw material. White, harder than brown corundum The brick is slightly higher and the toughness is slightly lower. Made into abrasive tools suitable for the grinding of high carbon steel, high speed steel and quenched steel.
4. Zirconium corundum brick is made by smelting alumina and zirconia as raw materials in an electric arc furnace at a high temperature of over 2000℃. Tough texture, dense structure and high strength. The main mineral phase of zirconium corundum is a eutectic formed by a-alumina and alumina-zirconia.
5. Chrome corundum bricks is a solid solution synthesized by high-temperature melting of aluminum oxide and chromium oxide in a certain proportion. The use of special refractory material production technology to make refractory bricks can improve and enhance the internal quality of the product and the high temperature performance of the product.
