Development Practice ofφ12 mm Hot-rolled Ribbed Steel Bar Four-strand Split Rolling
Abstract：Under the condition of existing process equipment in the bar production line, changing the motor speed by changing the finishing area reduction ratio, controlling the four-strand difference by different equivalent circle design for pre-segmentation pass and slicing pass, changing qualitative reverse guide and guard into quantitative reverse the guide and guard for unifying the torsion angles of four strands and widening the U-shaped groove etc, Zhangdian Steel realized the four-strand split rolling of φ12 mm hot-rolled ribbed steel bars. The success of the four-slit rolling made the daily output of the reinforced bars reach more than 3 400 t and the percent of pass of the product is 99.86%.
