Castables for ladle working layer is made from high purity corundum, magnesium aluminate spinel and fused MgO as main aggregates, superfine powder bonding technology and appropriate additives.
Advantages of Castables for ladle working layer:
Castables for ladle working layer is featured with good placement properties, high strength, better volume stability, better corrosion and abrasion resistance and thermal shock resistance. In case of re-lining technique is applied, the life of ladle lining can be further prolonged and refractory consumption per ton steel produced can be further reduced, which is proven to be an effective way for low specific refractory consumption and resource saving.
Applications of Castables for ladle working layer:
Working layer and bottom and Slag line of small
Bottom and working layer of large-and medium-capacity ladle
