Abstract: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.
Key Words: head bending; heating; rolling mill; guide and guard; fixed diameter rolling
