Fire clay refractory mortar is normally divided into four types according to physical and chemical indexes. It is mainly the auxiliary product for fire clay brick construction,with the refractoriness of 1580~1750℃, water content of ≤6%. The Fe2O3 content in refractory mortar for blast furnace construction shouldn’t be over 2.5%.
Basic tundish gunning mass is binding with inorganic binders,and no harmful gas released when baking, no environmental pollution,reduce the phosphorus, carbon pollution, and can purify the molten steel,which can meet the requirements of different types of steel smelting,meet the iron and steel industry continuous operation requirements,improve the molten steel output and economic benefit.
Hongda high performance refractory castables include low cement,ultra low cement and anhydrous castables,characteristics with high strength,good volume stability,good thermal shock resistance.
Fused silica spout ; The product has good thermal shock stability in the process of use, with high strength, resistance to scouring, erosion and other properties, and can save production costs and reduce the cost of continuous casting.
