First fully hydraulic aluminum hot rolling mill in Russia

Kamensk Uralsky Metallurgical Works banks on Siemens technology

(PresseBox) ( Moscow, Russia, )
The Russian aluminum processing company, the Kamensk Uralsky Metallurgical Works (KUMZ), now has the first fully hydraulic hot rolling mill in Russia. Siemens VAI Metals Technologies supplied Top Hat hydraulic cylinders and an automatic gauge control system for the new mill. With the new equipment, which is worth around two million euros, KUMZ can reduce the tolerance of its end products even further. The acceptance certificate was issued in April 2009.

Kamensk Uralsky Metallurgical Works is one of the biggest manufacturers of aluminum products in Russia. For more than 60 years, the company has been manufacturing semi-finished goods made of aluminum, magnesium and aluminum-lithium alloys. Installation of the new hydraulic Top Hat cylinders and the automatic gauge control (AGC) is part of a modernization project in the Kamensk-Uralsky factory near Yekaterinburg.

The two new hydraulic top-hat cylinders deliver a combined rolling force of 3,200 metric tons to the roll bite. With the help of the in-pass AGC during the final pass, considerably higher levels of precision as regards the thickness of the finished product can be achieved. An automatic "mill set-up" function shortens the times between passes as well as the slab to slab rolling times. An integrated data logging system provides the customer with important information on the rolling process and the behavior of the mill load. All the systems and components used are part of Siroll ALU, the integrated solution platform from Siemens for aluminum hot rolling mills.

The scope of supply also encompasses the hydraulic power unit and the valve stands. Siemens was also responsible for commissioning and on-site training.
