Abstract

IDC, Interstand Dimension Control, introduced to the market 1998 is now launching the next generation of U Gauges and IDC concept configuration. Field experience is proving not only improved product tolerances but also increased mill productivity. In a typical mill, the tolerances can be halved with IDC implemented compared to the normal performance. Final rounds in the range of 60 -70 mm have been rolled to a 1/8 DIN tolerance via 2-3 IDC controls in a 4-6 Horizontal/Vertical mill stand configuration. The same tolerances are achieved for 20 mm round dimension rolled width 3 IDC controls. The IDC system gives the rollers immediate measurements of Height, Width and position of the bar out of a roll gap. The rollers immediate response to how the mechanical adjustments of roll gap, rolls and guides will affect the bar dimensions and position out of a stand will result in a more consistence mill setup and improved pass schedules.Our ABM 2005 paper will give an overview to the IDC concept as well as results and experience from rolling mill installations.
