The production process comprises the following steps: firstly, a shot blasting machine and/or a sharpening machine are/is adopted to carry out finishing treatment on the surface defects of the bar steel, and then the bar steel after finishing treatment is sent to different next branch plants according to the length to be rolled so as to obtain bars, wires, plates and the like. The steel bars are heated in the heating furnaces in the corresponding next branch plants before being rolled, because the sizes of the heating furnace hearth in each next branch plant and the trolley sizing block in the heating furnace are fixed, only the steel bars within the corresponding length range can be heated, if the length of the steel bars is too long, the steel bars cannot enter the heating furnace for heating, even if the steel bars can enter the heating furnace, when the trolley moves, the too long steel bars damage the heating furnace hearths, the rolling efficiency of the steel bars is influenced, and the maintenance cost is increased; if the length of the bar steel is too short, the bar steel cannot be supported by the trolley sizing block, the heating effect is influenced, the later rolling effect is further influenced, and the rolling quality is reduced.
