Alumina-magnesite Carbon Brick for Ladle
Alumina-magnesite Carbon Bricks uses high grade bauxite clinker, fused corundum, fused magnesia and high-carbon graphite as raw material, uses phenolic resin as bonding agent, and it is shaped by high pressure. This product is characterized by low apparent porosity, high slag resistance and strong erosion wash-out resistance. During using period, spinel constructure would appear, in which way can increase materials' spalling resistance and slag resistance. Alumina-magnesite Carbon Bricks are mainly used in ladle wall and bottom.
