SMS Meer Delivers Most Powerful Screw Press to Wuxi Turbine Blade
08/23/2011 - SMS Meer recently started up the world’s most powerful clutch-operated screw press, three months earlier than planned, at the Wuxi plant of Wuxi Turbine Blade Co. Ltd.
SMS Meer recently started up the world’s most powerful clutch-operated screw press, three months earlier than planned, at the Wuxi plant (Jiangsu Province, China) of Wuxi Turbine Blade Co. Ltd. (WTB)
The new screw press, which has 35,500 tonnes of impact force, will enable Wuxi Turbine Blade to produce forgings of high-strength alloys for power station plants and the aircraft industry.
The new plant combines the benefits of forging hammer and hydraulic press to achieve forging to be achieved with a small number of strokes. The machine guarantees high forming forces with short workpiece contact time while achieving a homogeneous material microstructure, thus delivering both high productivity and quality.
The heart of the plant is the 1,320-mm diameter, 85-tonne screw. The energy-efficient press requires a variable-frequency drive power of only 500 kW — 87 % less than a conventional screw press, but with a simultaneous increase in the forming energy.
The new plant also features variable impact speed for the dies, which will enable Wuxi Turbine Blade to forge more-sophisticated parts than to date. “For us the plant has the advantage of being able to meet the growing demands of our customers from the aircraft and power plant industries,” said Yan Qi, Managing Director of WTB. “We have been working together successfully with SMS Meer since 1976.”
SMS Meer’s first large press went into production at Wuxi Turbine Blade back in 1995. Many years of good cooperation between the two companies enabled erection and commissioning to be completed in just nine months, so that the plant was able to go into production three months before the contractually agreed date.
While the new machine was being erected, SMS Meer also modernized components of the old plant. “SMS Meer not only supplies top-quality screw presses, but is also available for the customer after commissioning to ensure optimum service,” added Norbert Gober, Vice President Closed-Die Forges at SMS Meer.
SMS Meer GmbH is a company of the SMS group, which is, under SMS Holding GmbH, a group of companies internationally active in plant construction and mechanical engineering for the steel and nonferrous metals industry. It comprises the two Business Areas SMS Siemag and SMS Meer. In 2010, some 9,200 employees worldwide generated a turnover of EUR 3 billion.
