Electric smelting Zircon Mullite 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 Zircon Mullite 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. Temperature are important factors that affect chemical reactions and dissolved. When the temperature rises, the ions in glass melt in electric smelting zircon mullite products ions move faster also make electric smelting zirconium corundum brick saturated concentration of ionic liquid in glass to grow significantly, thus speeding up erosion. Also, too high a temperature will cause melting of materials.
