Product Introduction

The refractory castable for the ladle working layer produced by our company is made of corundum, high-purity magnesium aluminum spinel and fused magnesia as the main raw materials, and is made of micro-powder combination technology and admixture. It has the characteristics of good construction performance, high strength, good volume stability, good erosion resistance, erosion resistance and thermal shock resistance, and is suitable for pouring large and medium-sized ladle walls. At the same time, combined with the characteristics of the use of castable, ladle working lining peeling sleeve pouring construction technology, not only makes the ladle's service life is greatly improved, but also significantly reduces the ladle working lining refractory material consumption, so that the ladle's ton steel refractory material consumption and cost reached the advanced level.
