Steel Fiber Reinforced Refractory Castable For Sale

Steel fiber reinforced refractory castable for sale is refractory material that is made of refractory aggregate, powder, binder and additive and steel fiber. In other word, it is produced by adding refractory steel fiber into the raw material to improve its strength and thermal shock resistance. Because of its high strength, wear resistance, and good thermal shock resistance, it has been widely used in the high-temperature wearable parts of the kiln, furnaces, and boilers and so on.

Buy Steel Fiber Reinforced Refractory Castable

Steel fiber reinforced castable is also called high strength refractory castable, or steel fiber refractory castable. It is made of special bauxite clinker as aggregate, high quality bauxite clinker and corundum powder as matrix, composite materials such as the superfine powder as binder and additives, and heat-resistant stainless steel fiber. It belongs to hydraulic refractory castable.

Steel fibers, about 0.6%-2.5%, that added to the castable can improve its strength, toughness, spalling resistance and thermal shock resistance. Because of such properties, it is excellent in high temperature fluctuations, and thus improve its service life. In addition, the steel fiber that is added to the castable restrains the shrink in the process of maintenance, baking and using. It also improves the mechanical shock resistance and wear resistance, thus avoids the rupture and spalling because of the cracks produced from the thermal stress and mechanical stress.
