OREANDA-NEWS. Waldrich Siegen machine is successfully processing the medium weight rolls in Uralmashzavod. The first upgrading campaign was carried out in the 2000s years. With the increase of orders for multi-ton rolls (up to 60 tons), it was decided to use this machine for processing those. But the large rolls are necked down under their loads almost 1 mm that is not acceptable by the technology. So at the beginning of 2014, it was decided to upgrade the Waldrich Siegen machine.

Specialists from Uralmashzavod and representatives from UralRemService company developed and produced some special backrests - devices that can hydraulically raise a roll 1 millimeter upwards.

"Currently, three indicators are placed on each processed roll which indicate whether there is any deflection under load or not. After that the roll is being adjusted by backrests", - said Alexander Dragalin Uralmashzavod Deputy Chief Technologist.

The updated machine can operate and produce high quality products of required volumes.

Mill rolls production is a priority for Uralmashzavod. So, Ural Factory of Heavy Machinery supported by Gasprombank developed and now implements a new program concerning development of the rolls production at the factory. Investments volume for this production will exceed 900 mln. RUR.

OJSC Uralmashzavod is one of the leaders on the Russian market of equipment for metallurgy, the mining industry, oil & gas industry, construction materials and energy. The company's development strategy aims to create a world-class machine-building enterprise that will be capable of providing its customers with comprehensive coverage of their equipment needs. With the support of Uralmashzavod's principal stockholder Gazprombank, an investment program for radical reconstruction of production processes has been developed and is underway.
