Steel fiber-reinforced castable is typically formulated using materials such as bauxite clinker, corundum, silicon carbide, and mullite as aggregates. The matrix consists of fine powders of high-quality bauxite clinker and corundum, combined with ultra-fine powders and composite materials as binders and additives, along with stainless steel heat-resistant fibers. ·High strength and excellent toughness. ·Superior thermal shock stability. ·Strong resistance to spalling and wear. ·Ideal for high-temperature zones with significant temperature fluctuations.
In CFB boilers:
Furnace outlet, sidewalls, and top sections.
Straight sections and tops of cyclone separators.
Recycle ducts and other critical areas.
In steelmaking：
Chemical kilns, and cement/ceramic rotary kiln inlets.
