TAKO-The new PLTCM at Thyssen Krupp Stahl AG in Beeckerwerth works

摘要

The cold strip mill #2 in the Beeckerwerth works of Thyssen Krupp Stahl AG (TKS) was built in 1964. Together with the Dortmund works it is the largest of the five cold rolling mills of TKS. Main part of the production is for the automotive industry. Figure 1 shows the layout of the Beeckerwerth cold strip mill with the new tandem mill TAKO. The constantly improving demand of the market regarding surface quality, mechanical-technological quality and tolerances of dimensions caused the existing tandem mill to be replaced by a new one. The new mill was designed to meet the well known demands of the customers to reduce weight. This leads to a growing use of higher strength material of larger width and smaller thickness. To avoid surface defects and thickness deviations out of discontinuous production processes and as well for economical reasons the new tandem mill was coupled with the existing pickling line. A future increase of the production capability of the pickling line was taken into consideration for the design of the tandem mill.
