张钢在现有棒材生产线工艺设备条件下,通过改变精轧区减速比的方法,改变电机转速;预切分孔型和切分孔型采用不同等效圆设计,控制4线差;定性扭转导卫改为定量扭转导卫,统一4线扭转角度;加宽U型槽等方案,实现了φ12 mm热轧带肋钢筋四切分轧制.四切分轧制的成功使钢筋的日产量达到3400 t以上,产品合格率达99.86%.
장강재현유봉재생산선공예설비조건하,통과개변정알구감속비적방법,개변전궤전속;예절분공형화절분공형채용불동등효원설계,공제4선차;정성뉴전도위개위정량뉴전도위,통일4선뉴전각도;가관U형조등방안,실현료φ12 mm열알대륵강근사절분알제.사절분알제적성공사강근적일산량체도3400 t이상,산품합격솔체99.86%.
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%.
