Steel-fiber reinforced castable
Al₂O₃: ≥80
Al₂O₃+SiC: ≤4
- Commodity name： Steel-fiber reinforced castable
Description
Introduction
Steel fiber reinforced resistant castables are made of super-grade bauxite clinker as aggregate, bauxite clinker and corundum fine powder as matrix, superfine powder and other composite materials as binder and additive, and stainless steel heat-resistant fiber. become. On the basis of high alumina clinker corundum as aggregate and powder, adding appropriate heat-resistant stainless steel fiber and trace additives, the hydraulic refractory castable has excellent resistance to rapid cooling, rapid heat, high strength, high temperature resistance Shock resistance, thermal shock wear resistance and other characteristics.
Steel fiber reinforced resistant castables have conventional high-temperature wear-resistant properties, and a certain amount of heat-resistant stainless steel fibers are added to its ingredients to prevent the difference in expansion between the aggregate and the matrix in the material at high temperatures, and in the The stress generated by the temperature gradient change when starting and stopping the furnace leads to the destruction of the furnace wall. At the same time, due to the addition of steel fibers, the overall strength of the furnace wall is greatly enhanced after the material is poured.
