Cast part cleaning

Both air and wheel blast technologies can be used to clean parts of the Rail industry. Factors such as the size, complexity and number of parts to be treated will determine the choice of machine. Visit the Foundry and Forge pages for further information about treating cast parts.

Railway axle cleaning

Jiuchang offers technology designed to clean railway wheelset axles before crack initiation testing and the end control of dimensions.

Non-destructive by ultrasonic test
Non-destructive by magnetography

The surface is completely cleaned with all paint and oxide traces removed by means of a shot blasting machine. CNC (automated) equipment is preferred to manual technology to remove the margin for error.

The shot blast machine (Es 11 x 22 H Ro S 2 m featured here) can clean 30 standard axles in an 8 hour shift, to a quality level of SA 2, SA 2.5 or SA 3 depending on the initial status of the railway axle. Recommended media: Steel grit LG 80 – 55 to 60 HRC.

Roughness results: 0.6 to 4 μm with the above mentioned media and adjustable working pressure, these results being dependent on the wheelset’s initial status and paint or rust thickness prior to the blasting process.
