Within the scope of the modernization project, Primetals will retrofit the existing roughing stand with new automatic bar manipulation systems at both the entry and the exit side, so that bars can be automatically rotated and moved to the desired position between two subsequent rolling passes. In addition, a new RR 458 Red Ring finishing reversing sliding stand will be installed, featuring a barrel length of 1,100 mm and a roll maximum working diameter of 580 mm. The finishing stand comes with a state-of-the-art concept for roll change operations, which facilitates changing and setting rolls within 30 min. The existing cooling bed will receive an automatic band sawing system, for bar cutting to lengths ranging from 3–12 m.
Primetals will also supply the fluid system, the MV power equipment, including MV/LV transformers, drives and motors, the field (level 0) and basic (level 1) automation and auxiliary systems, and will supervise erection and commissioning.
VÚHŽ a.s. is a small-lot producer of niche-market components including special rolled sections, like fine simple or double profiles mostly for the automotive industry. VÚHŽ a.s. has its roots in a state-owned steel research institute founded in 1948 and is now wholly owned by Třinecké železárny, with some 2.5 million t of steel per year the largest steel producer in the Czech Republic. Primetals and Třinecké železárny have already completed a number of joint projects in the past, including the construction of de-dusting systems, the modernization of a wire and bar line, and the installation of an outlet for bar-in-coil.
