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.
