Steel Fiber High Strength Wear Resistant Castable Introduction
Steel fiber high strength wear resistant castable is a refractory material with excellent wear resistance. A certain size of heat resistant steel fiber is added to the wear resistant refractory castable, and a mixed refractory material composed of refractory aggregate, binder and admixture is added, and pouring construction is adopted. Unshaped refractory with excellent wear resistance.
Steel Fiber High Strength Wear Resistant Castable Feature
1. It can inhibit the shrinkage of refractory castables during curing, baking and high temperature use.
2. Improve the toughness, mechanical shock resistance and mechanical strength of the refractory castable.
3. Improve the thermal shock resistance of the refractory castable.
3. Prevent the microcracks generated in the refractory castable from expanding or extending under the action of thermal stress and mechanical stress to cause cracking or spalling.

Steel Fiber High Strength Wear Resistant Castable Application
1. It is widely used in cement rotary kiln kiln mouth, cooling machine, coal injection pipe, decomposition furnace, preheater and other parts.
2.It is widely used in high temperature kiln lining of chemical, electric power, cement, steel smelting, non-ferrous metals and other industries.
3.Construction of industrial kiln linings only in contact with high temperature gas or solid materials, such as electric furnace top, ladle cover, furnace top, soaking furnace cover and furnace wall, heat treatment lining, high temperature cyclone lining , cement rotary kiln cooling cylinder lining, and vertical roaster lining. It can also be used for containers, launders and components that are not in continuous contact with high-temperature melts, such as electric furnace tapping tanks and spray metallurgy integral spray guns.
