Electric smelting Corundum Brick glass erosion from surface, surface tension of liquid products, erosion of glass size affect diffusion rate of erosion products size, natural erosion of fused bricks can also affect the speed. Theoretically, if the glass is not wetting electric smelting zirconium corundum brick, is not likely to be eroded. Also, interface rough degree effects to reaction than surface area size, also effects to erosion speed; community physiognomy number effects also larger, in gas, and liquid, and solid interface Department, such as liquid surface and bubble Department, liquid of mobile Yu rejection proliferation layer, thereby led to reaction accelerated, glass melt kiln in the, pool wall brick liquid surface Department erosion serious and in electric melt brick brick sewing Department up erosion, a important causes that is this.
Composition and structure of fused corundum brick：
Electric smelting Zircon Brick glass composition, quantity and crystalline phases in number, shape, size, and so on will affect the electric smelting zirconium corundum brick using effect. Glass phase of improving sintering property and thermal shock resistance of materials plays an important role in such areas, but in terms of corrosion resistance of the materials, but it is a weak link, will no doubt affect the melting furnace life. Grain size is too small, they cannot form a woven mesh structure, and dissolve in the liquid in glass speed, poor corrosion resistance; grains is too large, the porosity of the material, less erosion resistance. Therefore, less needle-like crystals or granular material made of interwoven structure more stable, with good corrosion resistance and longer life.
