Refractory castable is a kind of commonly used unshaped refractory materials in kiln. The refractory castables have different using properties and applications, so the raw materials are different, too. Why Add Steel Fiber into Refractory Castable? What’s the Function?

Steel fiber refractory castable is a kind of reinforced refractory castable used in kiln, owing to it has the characteristics of high strength, good thermal shock resistance, good abrasive resistance, so it is generally used to strengthen the strength and tenacity. The refractory castable which added steel fiber are high alumina refractory castable and corundum refractory castable, mainly applied to electric furnace roof, ladle bag cover, heat treatment lining road and other parts. Why Add Steel Fiber into Refractory Castable? What’s the Function? Now I will give you explaination.

Firstly, . Why Add Steel Fiber into Refractory Castable? What’s the Function?

In the production of refractory castables, some steel fiber products with different diameters will be added. The steel fiber is a kind of stainless steel or other steel products with heat-resistant and wear-resistant. The common steel fiber specifications are 20mm, 25mm, 30mm and 35mm, and the use effect of steel fiber castable with different lengths is better. Steel fiber reinforced castable is a kind of refractory castable with high strength, good thermal shock resistance and good wear resistance. Adding steel fiber to refractory castable can enhance the performance of castable and increase the use effect.

The Effect of Adding Steel Fiber in Refractory Castable

1. Enhance the toughness of the liner, improve the impact resistance and wear resistance.Steel fiber refractory castable is a kind of common refractory castable used in kiln, owing to it has the characteristics of high strength, good thermal shock resistance, good abrasive resistance
2. Improve the thermal shock resistance, and anti-crack and anti-stripping.
3. Inhibit line shrinkage after curing, drying and heat treatment.

The addition of steel fiber to the castable is to enhance the use effect after pouring, but the amount of the castable material added to the steel fiber is determined according to the requirements of the technical department. Too much steel fiber added into the castable can cause the damage of the high temperature lining after pouring, reduce the corrosion resistance of the lining, and influence the performance of the lining of the kiln.

Select and purchase steel fiber castables, choose the regular refractory castable manufacturers, according to the specific information of the kiln, adjust the concrete formula of steel fiber castable, and produce high quality steel fiber castables.
