China’s AVIC Shaanxi Hongyuan Aviation Forging Co. Ltd. put what it says is the world's largest clutch-operated screw press into operation at its site in Xi’an, Shaanxi Province. The SPKA-type clutch-operated screw press, which was supplied by SMS group, has a screw diameter of 1,330 millimeters (52 inches), a blow force of 365 MN, a gross power of 27,000 kJ and a weight of 2,900 tons. It offers flexibility when it comes to optimizing the forging process and requires far less stroke to achieve the preset ram speed than a conventional slipping-wheel screw press. This type of press is particularly suited for high-energy forging typically used for turbine blades or structural aircraft components.
Ampco-Pittsburgh Corp. completed the sale of its Canadian specialty steel subsidiary, ASW Steel Inc. (ASW), to Valbruna Canada Ltd., a subsidiary of Acciaierie Valbruna S.p.A., of Vicenza, Italy. With production facilities in Fort Wayne, Ind., and in Italy, Valbruna produces stainless steels, nickel alloys and titanium long products. It has an annual output of approximately 200,000 tons of specialty steels.
Cross-wedge rolling (CWR) is a forging technique in which a heated billet is formed by rolling it between two flat (or cylindrical parallel-axis) die plates. This article describes the CWR process and equipment as applied to the production of railroad screws and other similar products.
A recent company survey indicates that forgers are more concerned with the availability of qualified labor than its cost. Given that, the forging community should consider automation to minimize its labor requirements. Automated billet feeding is one area that can improve manufacturing efficiency and reduce labor costs.
Western Superconducting Technologies Co. Ltd. (WST) successfully put a 63-/80-MN two-column open-die forging press into service. Supplied by SMS group, the high-speed push-down press has a maximum press force of 63 MN and an upsetting force of 80 MN. Due to the advanced hydraulic and control systems installed, the press is capable of forging highly demanding and temperature-sensitive materials such as titanium and titanium alloys with extreme precision.
For the third consecutive time, Cleveland played host to the biennial Forge Fair, which was held on the shores of Lake Erie May 21-23, 2019. Nearly 2,000 attendees and 169 exhibitors made Forge Fair 2019 the largest ever.
This fourth article about Germany’s Lightweight Forging Initiative (now with international industry support) focuses on potential weight savings through innovative material selection and forging part and process design. This continuation of the article from June examines additional specific lightweighting opportunities on a hybrid car and a heavy-duty truck.
