Steel fiber reinforced castable is made of superior bauxite clinker as aggregate, high quality bauxite clinker and corundum fine powder as matrix, ultrafine powder and other composite materials as binder and additive, plus stainless steel heat-resistant fiber.At the same time, due to the addition of steel fiber, the overall strength of the furnace wall is greatly enhanced after the steel fiber reinforced castable is poured.
On the basis of using high aluminum clinker as aggregate and powder material for its important part, adding appropriate steel fiber casting to strengthen castable is characterized by high strength, good toughness, good thermal shock stability, strong spalling resistance and wear resistance, etc. It is used in the parts where temperature ladder change is more likely to lead to furnace wall damage.
In fact, the use method of steel fiber reinforced castable is basically the same as the use of concrete. It is preferred to select a good formula and raw materials after mixing and processing evenly, use vibrator to compact, and then after curing and heating treatment.
