The invention discloses a production method for a hot rolled and pickled sheet. The production method comprises the following steps that a slab is heated and discharged out of a furnace at low temperature which is controlled to be 1150-1190 DEG C; the heated slab is subjected to rough rolling and rough descaling treatment, and an intermediate slab is obtained; the intermediate slab is subjected toheat-insulation coiling in a sheet coiling box, and then subjected to precision descaling and precision rolling treatment, and precision rolled strip steel is obtained; when the intermediate slab issubjected to precision rolling, the precision rolling inlet temperature is controlled to be 960-1000 DEG C, and the finish rolling temperature is controlled to be 840-880 DEG C; the precision rolled strip steel is flattened; and the flattened strip steel is subjected to acid pickling treatment. The technical problem that a hot rolled and pickled sheet in the prior art has surface quality defects is solved, and the technical effect of overcoming the surface quality defects of the hot rolled and pickled sheet is realized.
