Method for producing 42CrMoA by deoxidizing silicon carbide

The invention relates to the technical field of medium-carbon alloy steel production processes, in particular to a method for producing 42CrMoA by deoxidizing silicon carbide, which comprises the following steps: adopting a 120t converter for primary smelting, sequentially adding silicon carbide, alloy and lime after 1/4 of converter tapping, and controlling the endpoint carbon content of the converter; after converter tapping is finished, transferring to an LF station, feeding an aluminum wire, and then electrifying and heating to make white slag; argon is blown from the bottom of a steel ladle in the refining process to ensure the dynamic conditions of desulfurization and deoxidation; carrying out slag surface deoxidation by using calcium carbide and aluminum particles; adding lime to adjust alkalinity; after refining the white slag for 20 minutes, feeding an aluminum wire to adjust the aluminum content, and then feeding a silicon-calcium wire to carry out calcium treatment; after calcium treatment, the sof
