提高热轧带钢综合成材率的探索与实践

Study and practice of increasing comprehensive yield of hot-rolled strip coil

结合热轧带钢的生产工艺流程,发现影响热轧成材率的关键因素为烧损、切损、轧线废钢及成品判废。通过降低加热温度、改进精轧导卫系统、推行优化剪切、控制轧线废钢、提高精整车间管理水平及减少撞伤卷发生量等措施,能有效地减少热轧带钢在生产过程中的金属损失,较大地提高综合成材率。

In combination with hot-rolled strip production process,it’s found that burning loss,cutting loss,rolling scrap and rejected finish products are the critical factors affecting the rolling yield.By reducing the heating temperature,improving the rolling guide system,carrying out the optimization of shear,controlling rolling scrap,raising the management level of finishing workshop and reducing the volume of banged coils in the rolling process,the metal loss can be effectively reduced and the finished product rate improved greatly.
