Andritz received an order from Allegro, a subsidiary of Evraz and RailService established to produce train wheels in Russia, for a complete production line for train wheels. The production process includes several stages. Blanks produced by Evraz are heated to 2282°F (1250°C) in a rotary-hearth furnace, then descaled and pre-formed in a hydraulic press with 10,000 tons of press force. The blanks are then rolled in a wheel-rolling machine developed by Schuler and forged into a finished product in a crimping and piercing press with 5,000 tons of press force. This is followed by a geometric test in a laser measuring system and permanent marking in a marking press. Finally, the wheels undergo heat treatment, and the running surfaces are hardened.
ParkOhio completed the previously announced acquisition of Erie Press Systems (formally EFCO Inc.) of Erie, Pa. Erie Press manufactures advanced forging presses, hydraulic and mechanical presses, and metal stretch-forming and carbon extrusion machines for end markets including aerospace and defense, primary metals and high-speed rail.
SMS group received a contract from Chinese steel and forging company Daye Special Steel Co. Ltd. for the engineering and delivery of a high-speed hydraulic open-die forging press. The press operates with a forging force of up to 50 MN and an upsetting force of 60 MN. Daye Special Steel opted for the stable, four-column push-down press with moving crosshead. The high forging frequency of the press enables sophisticated materials requiring a narrow temperature range to be forged and reduces machining times.
