Solid railroad axles can be produced with a variety of metal-forming techniques. This article reviews these techniques and focuses on a more recent method called skew rolling, which is performed using three rolls to form an axle profile according to product specifications.
A rail axle is a round steel rod whose cross section varies along its length to conform to the individual purpose of the parts and stresses that occurs in it. The types of unfinished axles that may be produced, depending on the production method, include solid axles and hollow axles.
According to a local report, the Lawrence County Planning Commission accepted a land-development plan for an addition to Ellwood Specialty Steel’s production facility in New Castle, Pa. The plan calls for a 10,800-square-foot addition and a 7,560-square-foot lean-to structure, both at the back of the existing building. The purpose of the expansion is to increase capacity for a product the company distributes, sales of which have been growing, according to a company spokesperson. Ellwood Specialty Steel is a fully integrated producer of tool steels for forging dies, die-cast dies and other tooling applications. The company utilizes primary melting, refining and degassing equipment, along with ESR and VAR processes, to manufacture premium steel ingots.
Forge shops can increase productivity and reduce costs in hot-forging and heat-treatment processes using synthetic lubricants and/or protective coatings. Hard coatings cold-welded onto high-wear areas of dies or anti-oxidation coatings painted directly onto forging billets can help.
Protective coatings continue to play a major role in increasing productivity and reducing costs in hot forging and heat treatment. This paper presents details and successful case studies of three such protective coatings.
Arlington Capital Partners, a Washington, D.C.-based private-equity firm, acquired Firth Rixson Forgings Ltd. from Arconic. Going forward, the business will operate as part of Forged Solutions Group, which was formed in November 2019 by Arlington Capital as its aerospace forging platform. Located in Sheffield, United Kingdom, Firth Rixson provides complex closed-die forgings and forged discs and proprietary forward-and-backward extrusion-produced shafts and cylinders primarily for OEM and Tier 1 aerospace and defense engine customers.
Ring-rolling simulations have matured into a necessary tool for the efficient production of defect-free rings. Most defects encountered in production can now reliably be detected in a simulation, and solutions for the defects can be quickly implemented and verified. The optimized ring-rolling technology-chain simulation virtually ensures a defect-free product, and the information from the successful simulation can be used to set the operating parameters of your rolling mill.
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.
The 23rd International Forging Congress (IFC), to be held in Chicago Sept. 19-21, 2020, issued its call for presentations. The event, which will immediately follow the IMTS show, will showcase the best in technical and business-oriented presentations for the worldwide forging community. The IFC Planning Committee is calling for presentations now through Aug. 31, 2019.
Forgital, a producer of large forged and machined components for the aerospace and other industries, will be acquired by global investment firm The Carlyle Group. The transaction values Forgital at approximately $1.1 billion and is expected to be completed in the second half of 2019. Established in 1873 with headquarters in Vicenza, Italy, Forgital is a specialist in the manufacture of machine-finished forged and laminated rolled rings made from different materials, including steel, aluminum, titanium and nickel-based alloys. In addition to aerospace applications, Forgital also serves the oil-and-gas, construction, mining and power-generation industries. The company employs over 1,100 people across nine facilities in Italy, France and the United States and through its global salesforce.
FIA will hold its biennial Forge Fair May 21-23 at Cleveland’s Huntington Convention Center. This article, geared to the less experienced tradeshow attendee, will give you tips on how to make the most of your time on the exhibit floor and in the technical sessions.
