Summary

New refractories have recently been developed that not only have increased corrosion resistance to insulating wool fiber glass but also have lower thermal conductivity, thereby reducing energy loss. These new refractories also have good thermal shock resistance which is required due to the rapid heat-up and cooling of these furnaces (often only a matter of hours) when repairing or shutting them down. One such product is a rebonded fused AZS grain refractory containing 30% chromic oxide in the matrix with crushed fused AZS refractory used as the coarse aggregate in the body.
