What is the best ladle refractory castable with steel furnace

The ladle refractory castable is made of high-quality high alumina, corundum and high-quality magnesia as the main materials, and high-purity fused corundum as the main material. The matrix is mixed with high-purity spinel. It is an amorphous refractory made of composite micro powder and some additives.

Features of ladle refractory castable

  • Good explosion protection
  • High temperature resistance
  • High degree of volume stability
