Description

Technical Field

[0001] The invention relates to the technical field of metal plate cleaning, in particular to an oxalic acid degreasing furnace used for degreasing micro-precision thin-walled metal structural parts. Background Art

[0002] The oxalic acid degreasing furnace process reaction is a process commonly used in metal surface treatment. It is mainly used to remove grease and dirt on the metal surface to improve the surface quality and adhesion of the metal. The oxalic acid degreasing furnace is a metallurgical industry equipment that uses steam as a catalyst to quickly remove grease and other substances on the metal. Degreasing is a key technology in metal production technology. In the process of industrial production, the degreasing rate of metal workpieces is the most concerned technology for this type of equipment. At the same time, it is also necessary to pay attention to avoid deformation and dimensional changes of metal products. Because it is catalytic degreasing, the degreasing time is greatly shortened, thereby reducing costs, and it can also clean larger metal plates.

[0003] When degreasing metal plates, the appearance and size of precision metals need to be strictly controlled. Therefore, during the production process, it is necessary to always pay attention to the stability of the plates, and also to pay attention to whether the plates will be corroded or damaged. However, during the catalytic degreasing stage, the current technology cannot accurately control the steam, and timely remove substances such as oxalic acid adhering to the metal plates. If this aspect is not well controlled, it will cause corrosion damage to the metal workpiece. At the same time, when facing some thick grease, the catalytic effect of oxalic acid will be greatly reduced. At this time, it is also necessary to manually set the degreasing time mode, resulting in the product not being cleaned in time. Summary of the invention
