The invention belongs to the technical field of steel manufacturing and particularly relates to a production method of super extra-deep drawing quality IF steel. The super extra-deep drawing quality IF steel contains the following chemical components in percentage by weight: more than 0 and less than or equal to 0.004Wt% of C, more than 0 and less than or equal to 0.03Wt% of Si, more than 0 and less than or equal to 0.25Wt% of Mn, more than 0 and less than or equal to 0.025Wt% of P, more than 0 and less than or equal to 0.02Wt% of S, more than or equal to 0.05Wt% and less than or equal to 0.09Wt% of Ti, more than 0 and less than or equal to 0.0035Wt% of N and the balance of iron and inevitable trace elements. The production method comprises the following steps: blast furnace molten iron melting, KR-method desulfuration treatment, converter molten steel melting, RH-method molten steel refining, slab continuous casting, conventional hot continuous casting, acid pickling cold continuous rolling, hot galvanizing horizontal furnace annealing, finishing and bundling. According to the production method provided by the invention, the SEDDQ IF steel can be produced by virtue of a hot galvanizing horizontal furnace annealing process.
