Train Wheelsets and Tyres Rolling
Train wheelsets and tyres rolling is an important industrial practice by which the complexity of rotatable wheels is reduced, making mass engineering production cheaper. This process is a key part of the production of railway components, as it creates the final product used on the track.
In train wheelsets and tyres rolling, the wheels are heated and then pressed through a mould or dieset. The heat recommends the metal, making it softer and more malleable. Rolling then closed the metal grains of the steel, making the components stronger and smoother. Wheelsets and tyres are typically hot rolled, but there are other methods such as cold rolling. After rolling, the components are formed and machined for further usage. Railway wheelsets and tyres must all pass strict quality control standards to ensure their safety and performance on the track.
To create train wheels, steel plates must first be cut and joined. The plates are then heated, rolled and machined for uniformity. The forming part of the process is highly crucial, as it likely affects the fitment and running of the wheels. Tyres are also rolled for uniformity and machined for precision running.
Train wheels are most commonly made from cast and forged steel. Forged steel has a greater tensile strength than cast steel and is usually used on locomotives and heavy freight carriages. The rolling process allows the engineer to shape and control the components, adding strength and rigidity.
The main advantages of rolling wheelsets and tyres are: accuracy of design, longer service lifespan of the parts, lower costs in manufacture and lower fuel consumption. The process of rolling is much more efficient than manual forming, as it requires less costly engineering and equipment. The cost savings in labour and maintenance, as well as the enhanced accuracy, ensures that rolling is still remain the most popular production process for train wheels and tyres.
Rolling is a popular option for producing high-grade and performance components. Rolling produces softer, more malleable components, allowing for greater energy transfer, lower friction and reduced overall maintenance.
The process of rolling is of particular importance for railway components. Mass engineering production can produce high-grade components, at lower cost and without fail, making train wheelsets and tyres the most important components for railway networks around the world. Rolling and machining can create highly specified, precision components that are light, strong and reliable. Rolling also helps to reduce noise and rubbish, allowing for smoother running of carriages and railway networks.
