Product Description:
Steel fiber high strength castable is made of bauxite clinker as aggregate, high quality bauxite clinker as matrix, superfine powder and other composite materials as binder and additive, plus stainless steel heat resistant fiber.Product Features:
The product besides with the conventional high temperature wear resistance performance, because in its ingredients added a certain quantity of heat resistant stainless steel fiber, prevent the material in the aggregate and matrix under high temperature condition of rose is poor, and stop at the exit of furnace temperature gradient changes of stress caused by the furnace wall damage, at the same time, because of the addition of steel fiber, to greatly enhance the strength of materials after pouring furnace as a whole.Product Advantage:
High strength, good toughness and thermal shock stability, anti - peeling and wear - resistant.| Steel Fiber Reinforced Refractory Castable | ||||
