本钢特钢中棒材头部弯曲改善

IMPROVEMENT OF HEAD BENDING OF BARS IN BENXI SPECIAL STEEL

分析本钢特钢中棒材头部弯曲产生的原因,通过优化加热工艺、新增定径轧制工艺、改进出入口导卫固定方式与出口导卫内堂尺寸,有效降低了中棒材头部弯曲度及弯曲比例,显著提升钢材外观质量,减少金属损失,降低了生产成本。

This article analyze the reasons for the bending of the head of the bars in Benxi special steel.By optimizing the heating process,adding a fixed diameter rolling process,improving the fixing method of the inlet and outlet guide and the size of the outlet guide,the bending degree and proportion of the head of the bar have been effectively reduced,significantly improving the appearance quality of the steel,reducing metal loss,and lowering production costs.
