When metal materials are thermoplastic formed such as forging, oxidation occurs due to high temperatures. A layer of dense oxide skin (scale skin) is formed on the surface, which adversely affects the quality of the forgings as well as the subsequent processing. In addition, the hot forming process of non-ferrous metals such as titanium alloys also requires special lubrication and insulation measures such as glass lubricants, which are attached to the surface of the forgings after forming and need to be removed before subsequent processing.
With the technological development of equipment manufacturing and vehicle manufacturing, especially in the automotive parts category, a large number of drop-forged workpieces are required, their weight is getting smaller and smaller as well as being highly dependent on energy efficiency and material utilization. In addition to mechanical properties and process requirements, increasingly stringent surface quality requirements are also in focus. The removal of oxide from forgings has become an important issue.
In the world of forging field, high-pressure water descaling (i.e. oxide removal), has been an important process in forging manufacturing (especially hot die forging), which not only improves the quality of forging products, but also reduces the prefabricated size of the billet, reduces die wear, significantly reduces the difficulty of post-processing processing and machining volume, etc., directly or indirectly reducing a large amount of production costs for enterprises.
Therefore forgings descaling not only improves the product qualification rate but also improves the service life of abrasives and reduces raw material costs. To learn more about the forging descaling process, please contact us.
