Chinese steel and forging company Daye Special Steel Co., Ltd., based in Huangshi City, Hubei, has awarded SMS group the contract for the engineering and delivery of a 50/60 MN, high-speed hydraulic open-die forging press. Once again, the customer is placing its confidence in forging press technology from SMS group: Daye has been using an SMX 800/16 MN radial forging machine, supplied by SMS group, since 2011.

The open-die forging press operates with a forging force of up to 50 MN and an upsetting force of 60 MN. Daye opted for the stable, four-column push-down press with moving crosshead. The high forging frequency of the press not only enables sophisticated materials requiring a narrow temperature range to be forged, it also reduces machining times. During planishing, the new press is capable of reaching a frequency of 103 strokes per minute. Daye Special Steel plans to use the new open-die press to forge a variety of products of high-temperature alloys and special steel.

This open-die forging press to be provided by SMS group to Daye Special Steel can be operated in fully automatic, semi-automatic, or manual mode. Daye Special Steel will be able to forge materials extremely precisely and energy-efficiently in program mode, using pass schedules that are precalculated with the ForgeBase® forging program. In addition, the press will feature a press control and visualization system, which was developed by SMS group and will allow Daye Special Steel to attain maximum reproducible product quality with a forging tolerance of around ±1 millimeter. For fast die changes the machine will be equipped with a forging die changing device.

The open-die forging press is to be installed in the Huangshi plant. Commissioning is scheduled for May 2020.

SMS group is a group of companies internationally active in plant construction and mechanical engineering for the steel and nonferrous metals industry. It has some 14,000 employees who generate worldwide sales of about EUR 3 billion. The sole owner of the holding company SMS GmbH is the Familie Weiss Foundation.
