Product Description:
Fused zirconia corundum bricks are made of zircon sand, zircon fine powder and alumina powder as the main raw materials, which are melted at high temperature in an electric arc furnace, cast, cooled and demolded for further processing.Advantages:
good high temperature performance, good thermal shock stability, corrosion resistance, long service life.Application:
It is often used in glass furnace melting pool bottom and pool wall, breast wall of melting part, neck, small furnace bottom brick and other parts, as well as slideway in steel industry, sodium hydroxide industry, etc.|
