棒材全连轧工艺优化

Process Optimization of Full Continuous Rolling of Bars

通过对粗轧孔型的侧壁、槽底以及宽度的修改,解决了粗轧轧件出耳子、扭转和压下量过大等问题;通过对导卫结构形式和安装方式的改造解决了导卫系统安装调整复杂的问题;通过对活套器增加红外探测孔,修改控制程序,解决了活套器单线起套过高和中途起落套的问题。优化改进后,济钢一小型厂棒材全连轧生产线月产量由4.3万t提高到10万t以上。

The problems of rough rolling stock such as rolling edge,torsion and bigger reduction were resolved by amending the sidewall,bottom and width of the roughing pass.The complicated matter of guide system＇s installation and adjustment was untied by means of change for guide structure form and installation wise.The problems of loop＇s monocable higher uprising and midway up or down were settled by adding infrared plumb hole and modifying control program.After a series of optimization and improvement,the mensal output of the bar full continuous rolling line in Jinan Steel＇s No.1 Small-scale Mill was increased to100 thousand tons above from 43 thousand tons.
