  • This The layout of the individual road sections has several Advantages: The required space for the scaffolding is minimized. The entire length of the rolling mill will reduced because the compact frameworks are closer together can be positioned; they are not roller tables either required between the scaffolding. Because of the Standardization of the optimized roll change will the stock of spare parts is low.
  • the changeover times are shortened.
  • the proposed one is particularly advantageous Use of a two-stand vertical-horizontal mini-block with overhung rollers as a replacement for the tilting and rotating scaffolds previously used, if, for example, the single-strand rolled stock to be subjected to a separation roll. Because in the case of separation rolling of the rolling stock, only the horizontal rolling unit is used the scaffolding for the separating stitch in use, while in the case of normal rolling only Vertical unit is in operation. The other rolling unit you just let it run empty or it will appropriate roll cassette removed.
