Measurement of the relative reduction of strip on the 1200-model temper-rolling mills in flat-rolled products shop No. 3

The temper-rolling mills in flat-rolled products shop No. 3 at the MMK has been equipped with the Vytyazhka automated system to measure the elongation of strip (ASEMS) rolled on the mill. The elongation (relative elongation) of the strip is determined through a frequency-based method of measuring the speed of the strip before and after reduction. The system transmits and displays information on the temper-rolling of each coil. The information is shown as a diagram on the monitor of an industrial computer. The reliability of the system allows it to be in continuous use. Introduction of the automated elongation measurement system makes it possible to monitor the reductions being made during temperrolling, which in turn enables the shop to reduce the number of products having properties that do not meet customers’ requirements. __________ Translated from Metallurg, No. 1, pp. 62–63, January, 2007.
