Background

The bar steel, i.e. the bar billet, includes the continuous casting billet and the blooming billet, is mainly used for producing bars, wires, plates and the like. 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.

At present, the rod-in-one factory of Shanghai five-steel equipment engineering Limited company can process 4600 mm-6000 mm long bar steel; the rod II factory can process the bar steel with the length of 3100 mm-4000 mm, and the short ruler is more than or equal to 2600 mm; the length of the wire rod can be 8000 mm-10000 mm; the forging mill can process bar steel with the length of 1800 mm-3200 mm, and the short ruler is more than or equal to 1500 mm; in order to avoid that the strip steel with improper length enters a next branch factory, damages a hearth of a heating furnace and influences the rolling efficiency, all the strip steel is required to be measured in length one by one. So as to send the steel bars with proper length to the corresponding next branch plant for rolling; the common method for measuring the length of the bar steel is to manually measure by using a measuring tape, but the number of the bar steels to be measured is large (about 1.6 ten thousand bars/month), so the labor intensity of workers is greatly increased, and in the manual measurement, errors are easily caused, so that the overlong or overlong bar steels flow into a next branch factory, and unnecessary loss is caused.
