A brief introduction to the key points of the processing of automobile wheels

A steelmaking process for automobile wheel hub bearings is provided. Using this technology can achieve a greater degree of pouring in the molten steel furnace, improve production efficiency, reduce production costs, and improve the purity of molten steel. Next, the editor will take you to understand the automotive wheel hub Related processing points. A steelmaking process for automobile hub bearings includes raw material preparation, smelting, refining, vacuum treatment, and continuous casting in a converter using low-sulfide molten iron (Molten Iron S) Bottom-blown argon Gas, without ore blowing, no slag in the first 4 minutes and 13 minutes after blowing, and less than 24500 m3/h in the 14 minutes after blowing to transport oxygen into the molten steel flow. 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 above 0.15%, and the furnace temperature is controlled at 1630 ° C ~ 1660 ° C. The converter uses slide plates to produce steel and retain steel. There are 2 tons of steel, and 2 tons of aluminum are added to the filter cake to deoxidize the molten steel.
