Ф25 mm螺纹钢两切分轧制的预切分孔型优化

Optimization of Precutting Rolling Hole of Two-Slice Rolling of Ф25 mm Rebar

分析水钢二棒线两切分轧制Ф25 mm螺纹钢采用双控边、双预切工艺,轧制过程中因第一预切孔型设计存在缺陷,导致成品尾部尺寸超差,结合现场生产实践考虑对第一预切孔型重新设计解决此问题。

The double-edge control technique and double-precutting process of two-slice rolling of Ф25 mm rebar in No.2 rebar rolling line in Shuigang are analyzed.Due to the defects in the design of the first precutting rolling hole,the size of the end of the finished rebar is out of tolerance.In view of the field production practice,the first precutting rolling hole is redesigned to solve the problem.
