Steel Fiber Reinforced Refractory Castable for Boiler's lining
The Description:
Steel fiber reinforced refractory castable refers to a kind of refractory material that increases its strength by adding steel fiber to the amorphous refractory aggregate. Similarly, the addition of steel fibers to refractory plastics is called fiber reinforced refractory plastics.

Types and applications of steel fiber:
Commonly used fibers are ordinary steel fiber, heat-resistant (stainless) steel fiber, carbon fiber, alumina fiber, aluminum silicate fiber and organic fiber. From the point of view of strengthening and fire protection effect, heat-resistant steel fiber and alumina fiber are now commonly used to make high-strength refractory materials. The fire protection effect of ordinary steel fiber is poor, and the price of carbon fiber is higher, so it is used less. Organic fibers are often used as explosion-proof agents for dense high-strength refractory castables, and have certain applications.
Characteristics of steel fiber castable:
The type of steel fiber reinforced refractory castable can be named as high-aluminum steel fiber high-strength castable or corundum steel fiber reinforced refractory castable according to the material of aggregate and powder. These materials have the characteristics of high strength, good toughness, strong thermal shock resistance and good spalling resistance.
Application of steel fiber castable:
steel fiber castable is widely used in heat treatment furnace, heating furnace, soaking furnace, tundish slag weir, outside furnace scouring and catalytic cracking device and other key parts of kiln and thermal equipment, and has achieved good results in technology and economic benefits.
