voestalpine Stahl GmbH has awarded Primetals Technologies the order to supply further side guiding beams with wear discs for its hot strip mill in Linz. The Eco Slide Disc systems will be installed at the entry side guides of coilers 3 and 4. Eco Slide Discs have already been in continuous, successful operation at one guiding side of coiler 3 since August 2014. The order was. placed in response to the positive operating results and cost savings potentials. Eco Slide Discs can be used continuously for four weeks, whereas conventional wear strips last only two or three days. The new side guides have an inherent self-cleaning effect. This reduces the risk of material deposits falling on the strip and damaging its surface.
