The invention belongs to the field of metallurgy technology, and relates to a bar full-scale processing equipment and process, including an upstream steelmaking and continuous casting unit, a billet weighing unit, a temperature-controlled rolling forming unit, a flying shear unit, and a finished product finishing unit. whole processing unit. The upstream steelmaking and continuous casting unit includes continuous casting machines and corresponding auxiliary equipment. Billet weighing unit includes billet weighing equipment. The temperature-controlled rolling forming unit includes a continuous rolling unit, a temperature control device and shearing equipment arranged in sequence, and the flying shear unit includes flying shearing equipment. The finished product finishing unit contains finishing equipment. Its process steps adjust the billet weight through the upstream steelmaking unit through feedback regulation. The invention can improve the finished product rate of bar production and increase enterprise benefits; it can simplify the bar finishing collection system and reduce investment and operating costs; it can cancel finishing posts and realize unmanned finishing area; it can adapt to the large size of bars Large-scale and large-volume requirements; it can be adapted to direct rolling requirements.
Description
technical field [0001] The invention belongs to the technical field of metallurgy, and relates to a bar full-scale processing equipment and process. Background technique [0002] Bars are the largest form of steel, accounting for almost half of steel production. The finished bar is delivered in a straight-length state, and the length is generally 16m, 12m, 9m and other specifications. [0003] In traditional bar rolling, the billet is a fixed-length billet, so the total length of the rolled bar must not be an integral multiple of the final length of the finished product. As shown in the table below: [0004] [0005] It can be seen from the table that when the 12m length is produced according to the standard billet, short lengths of 5.38m, 5.36m, 6.39m, 7.88m, 10.34m, 4.17m, and 1.34m will appear. In addition, there is a certain deviation in the size of the blanks provided by the upstream (for example, the mold in the continuous casting process will gradually wear out ...
