Product Details
Refractory castable is product that is used in various part of furnace as Monolithic Refractories that added hydraulic alumina cement to refractory aggregate, Our Company is producing suitable product to installation and working condition through a quality control, this product which is minimizing alumina cement for using various dispersants and ultra fine powder so it has excellent abrasion resistance, erosion resistance, spalling resistance and chemical resistance . It widely used in part of various industrial furnace including incinerator, nonferrous metal furnace etc.
Features Of Refractory Castable
- High refractoriness, High refractoriness under load
- High density, low porosity
- Good slag resistance and corrosion resistance
- High strength and wear resistance
- Good resistance to flake performance
- Good thermal shock stability
- Scouring resistance
- Good hot strength
Applications Of Refractory Castable
mainly used in heat treatment furnace,heating furnace,soaking pit furnace,tundish slag dam weir,seconclary refining and the catalytic cracking unit etc key part of kiln furnace and thermal equipment.
