Abstract：The production line was revamped with addition of water cooling devices between roughing and intermediate trains and after finishing tain and a control system for adjustment of water flow rate, water temperature, water pressure, rolling piece temperature and position.The results show,that for ribbed bars of 20MnSi and 20MnSiNb 475m3/h of water flow rate, 1.5MPa of water pressure, 14.5m/s of rolling speed are suitable.
