Resumo

On June 23, 2000, the first coil went through the Sidmed revamped continuous Tandem Cold Mill, two years after the ACERALIA and SOLLAC co-owned company awarded the contract to VAI Cosim. The main purpose was to convert the 5-stand TCM to a fully continuous mill in order to increase the steel sheet production from 1.2 to 2 million tonnes per year, with the best performance in terms of gauge and shape tolerance. To achieve this, a completely new mill entry section with a double 675-meter capacity accumulator and a new double tension reel exit section have been installed. In the same time, an outstanding co-operation between SIDMED for the Level II, VAI Automation for the Process Control and ABB for the drives enabled to replace most of the existing controls, to interface, through a gateway, with the existing Westinghouse drive system and to quickly and smoothly re-start the mill in its continuous configuration. This presentation will describe the main technical features and show operating results after seven months of operations in continuous mode.
