Operational Experience and Productivity Improvements in Rod and Bar Mills with Interstand Dimensional Control

摘要

An increasing number of profile mills equipped with interstand dimension control (IDC) are generating industry interest regarding IDC results and achievements. The IDC approach of "make it right from the start" is attractive to those seeking to further improve their mills. This presentation will cover practical experiences and actual results from rod and bar mills with IDC in operation. Carbon and stainless steels will be addressed.IDC controls the mass flow between mill stands by changing stand speeds, acting on the interstand dimensions of the bar continuously provided by U-gauges. U-gauge measurement technology is based on pulsed eddy current technology and is not affected by scale, steam, vibrations, etc.
