This article examines the technology of cross-wedge rolling (CWR) in the production of railway axles, as well as new equipment for its realization.

Of all hardfacing applications, tool-and-die repairs are one of the most metallurgically challenging. What makes it so challenging is the metallurgy of the base materials and their compatibility with the hardfacing products, as well as the post-weld heat treatments required.

Metal-forming simulations are used to develop unique processing techniques by eliminating the high number of laboratory tests required in such research, but they are also used extensively for the predictive detection of possible material failures, forging force detection, proper die design and topology optimization in the industry.

In applications where life is (literally) on the line, simulations improve product quality, enhance safety and reduce process costs.

For the second consecutive time, Cleveland hosted Forge Fair during the first week of April. The event was a rousing success, as forging industry executives and technical experts from around the world converged on the shores of Lake Erie for three days of exhibitions and technical sessions.

Gerdau, a leading supplier of SBQ steel, has prepared to better serve the forging industry through modernizing its processes and equipment, finding ways to improve steel cleanliness and remaining intensely focused on forgers.

The Cleveland Convention Center will open its doors on April 4 to begin the first day of Forge Fair 2017, which will offer a full trade show and symposium programming.

The repair of worn forging dies by flood-welding techniques has been around for many decades. Advances in the evolution of the process have made it a cheaper, quicker and more effective way to extend the life of die blocks and reduce tool-steel inventory costs. Today, many forging companies consider flood welding an integral part of their routine die maintenance programs.

New alloy wires for the welding of metal-working forging dies, hammers and other metal-forming applications have been introduced.

Many of the North American forging industry’s most talented technical people recently gathered for two days of technology updates and presentations at the Nationwide Hotel and Conference Center in Columbus, Ohio.
