Steel Fiber Castables
Product Introduction
The main materials of steel fiber castables are special grade bauxite clinker, high-quality bauxite clinker and fine corundum powder. In production, it is necessary to add ultra-fine powder and other composite materials as binders and additives for steel fiber castables, and then add stainless steel heat-resistant fibers. Due to the addition of steel fibers, the overall strength of the furnace wall is greatly improved after the material is poured.
