Brief Introduction
Steel Fiber Castable Refractories are a kind of high strength Castable Refractory made of high alumina clinker or brown aluminium oxide as the aggregate and powder, and added binding agent and suitable heat-resistance stainless steel fibre and admixture.
Steel Fiber Castable Refractories can be classified into two types of stainless fiber Castable Refractory and nickeled stainless fiber reinforced refractory castable. Of which, nickeled stainless fiber reinforced refractory castable has better high temperature resistance property and resistance to rubbing. Also have good structure stability and gas tightness, physical & chemical property and great construction property.
Technical Data
The price of refractory castable varies depending on the brand, specification and application. The following are Rongsheng’s reference specifications, and our products support customization!
