Steel Fiber Castable

  • Steel Fiber Castable

Product Description And Parameters

Main Composition:SiO2 + Al2O3

Application:Steel and metallurgical, or other industrial kilns.

Main Raw Material:Bauxite

Color:Grey

Package:Export ton bag

The main materials of steel fiber castables are special grade bauxite clinker, high-quality bauxite clinker and fine corundum powder. In production, it is necessary to add ultra-fine powder and other composite materials as binders and additives for steel fiber castables, and then add stainless steel heat-resistant fibers. Due to the addition of steel fibers, the overall strength of the furnace wall is greatly improved after the material is poured.

Features
1.High Service Temperature.
2.Good wear resistance.
3.Long Service Life.

Application
It is widely used in steel, metallurgy, chemical and building materials industries; in CFB boilers, it is often used in furnace outlets, side walls, tops, straight sections of cyclones, tops of cyclones, and return materials.
