Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a screening device for metal powder processing. Background Art

[0002] Impurities are released from metal rings during sintering in a sintering furnace. This is primarily due to the high temperature during sintering, which causes the elements within the metal ring to rearrange and combine. It can also cause chemical reactions between the metal ring and the furnace atmosphere or surrounding materials. These reactions cause certain elements to volatilize, oxidize, reduce, or form new compounds, which are then released as impurities.

[0003] The main reasons for screening the metal rings and impurities adhering to the metal rings are as follows: First, the presence of impurities may affect the performance of the metal rings, such as electrical conductivity, thermal conductivity, mechanical strength, etc., and therefore need to be removed by screening; second, certain impurities may have adverse effects on subsequent processing, such as causing tool wear and affecting product quality; finally, screening also helps to recover valuable metal elements and improve resource utilization.

[0004] During the production and use of metal rings, various impurities often adhere to the rings, affecting not only their appearance but also their performance. Traditional methods for cleaning impurities from metal rings rely primarily on manual labor, which is not only inefficient but also prone to omissions or damage. The metal powder that is screened can be used for production and processing. To address this issue, we provide a screening device for metal powder processing. Utility Model Content
