[0002] In the metal heat treatment process, quenching is a key process for improving the hardness and wear resistance of a workpiece. However, before quenching, the surface of the workpiece is often attached with iron filings, dust and other impurities, which will affect the purity and stability of the quenching liquid, and thus reduce the quenching quality. At present, the industry generally focuses on the optimization of quenching process parameters, but the control of the cleanliness of the workpiece surface is less studied, resulting in frequent problems of quenching liquid pollution and unstable workpiece performance.

[0003] At present, the cleaning before quenching of spring steel wire mostly adopts a single cleaning method. Common workpiece surface cleaning methods include manual wiping, high-pressure gas blowing and chemical cleaning. Manual wiping is low in efficiency and unstable in cleaning effect; high-pressure gas blowing is difficult to completely remove small iron filings; although chemical cleaning has good effect, it has the problems of environmental pollution and high cost.
