关于高速棒材圆钢直线度的研究与实践

Research and Practice on Straightness of Round Steel

热轧圆钢产品对直线度要求高,直线度差会增加客户切损率。长钢轧钢厂针对连续发生的多起高棒圆钢因直线度差的质量异议,找出导致直线度差的原因,通过改造转毂、矫直冷床齿条以及降低精整工序钢材温度,有效提高了高棒圆钢产品质量。

Hot rolled round steel products have high straightness requirements,and the straightness difference will increase the cutting rate of customers.As to the quality objections occurred in Changgang high-bar round steel due to the straightness difference,the high-bar effectively improves the straightness of high-bar round steel products and reduces the quality problems by the transformation of the boss,the straightening of the cold bed rack,and the reduction of the finishing process steel temperature.
