Refractory castable for iron ladle

Molten iron ladle is a high-temperature equipment for holding molten iron. As a high-temperature lining material, the refractory castable of molten iron ladle has good erosion resistance and high-temperature erosion resistance.

Product Introduction

Molten iron ladle is a high-temperature equipment for holding molten iron. As a high-temperature lining material, the refractory castable of molten iron ladle has good erosion resistance and high-temperature erosion resistance.

When hot metal ladle is used to hold and transport molten iron, the liner of hot metal ladle shall endure high temperature, thermal shock, mechanical wear and chemical erosion of hot metal and slag. When pouring hot metal, the erosion of molten iron impacting zone is more serious. At that time, The working environment of hot metal ladle is alternately cold and hot, and the longer the interval period , the more serious the lining damage.Therefore, the lining of hot metal ladle generally chooses refractory with high corrosion resistance, high strength, antioxidant and good thermal shock resistance.

Refractory castable characteristic:

1.Good thermal shock resistance

2.Strong erosion resistance

3.Good anti-scouring,good wear resistance

4.Good antioxidant.
