  • Why there is Transverse Texture of Forged Steel during Cold Rolling Process
    Why there is Transverse Texture of Forged Steel during Cold Rolling Process
    2021-09-02

    Transverse grain defects are an important indicator that affects the surface quality of forged steel cold-rolled products. In many domestic cold forging steel mills, especially the galvanizing line and the continuous rolling line, it is very difficult to solve the transverse grain defect. The causes

    The so-called cold rolling production of forged steel is not simply "cold rolling". Annealing, pickling, grinding, etc. are required before cold rolling, and flattening, straightening, shearing, and stacking are required after cold rolling, so it is actually the whole process from the hot-rolled coi

    2021-08-23

    Back-up rolls are generally used in tension levelers, levelers, rolling mills and other equipment. Because the work roll is relatively long and slender, it cannot bear the radial load generated when straightening the plate shape and rolling the plate. At this time, it is necessary to arrange a suppo
