Analysis of steel smelting process for automobile hub bearings

The invention provides a steel smelting process for automobile wheel hub bearings, which can realize greater pouring in molten steel furnaces, improve production efficiency, reduce production costs, and improve the purity of molten steel. A steel smelting process for automobile wheel hub bearings includes raw material preparation, converter smelting, refining, vacuum treatment, and continuous casting. , do not add ore before blowing for 4 minutes, do not add slag after blowing for 13 minutes, and supply oxygen to molten steel with a small flow rate of less than 24500m3/h after blowing for 14 minutes. After oxygen blowing in the later stage, the oxygen content of molten steel increases, thereby improving the purity of molten steel and reducing the oxygen content of molten steel. The carbon content at the end of the converter is controlled at more than 0.15%, and the temperature of the converter is controlled between 1630 ° C and 1660 ° C. The converter adopts sliding plate tapping And carry out the steel retention operation, each furnace retains 2 tons of steel and 2 tons of aluminum and adds filter cake to deoxidize the molten steel.
