Research and Application of a Tension Calculation Model for Continuous Rolling of Rod and Wire

Tension control is a key technology in the rod and wire rolling process. Adoption of micro tension rolling in the rough and intermediate rolling area without loop can ensure stable product tolerance. To control micro tension rolling,it is necessary to judge the tension value or variation tendency between different mills. To achieve this purpose,this paper studies the tension calculation model for continuous rod and wire rolling,and through PLC calculation,applies the optimal tension calculation model to the producing of straight round steel so as to realize monitoring of micro tension rolling at the rough and intermediate stages and to raise product precision.
