Recently, the company obtained the invention patent certificate of “Continuous High Temperature Cleaning Molybdenum Wire Surface Device and Process” issued by the US Patent and Trademark Office. The patent number is US9328425B2, which is the company's first PCT patent.
The invention discloses an apparatus and process for continuously cleaning a surface of a molybdenum wire at a high temperature. The thermochemical method is used to remove harmful substances such as carbon and molybdenum oxide on the surface of the molybdenum wire, thereby achieving the purpose of cleaning the surface of the molybdenum wire, and at the same time eliminating the stress accumulated during the drawing process of the molybdenum wire. There is no waste liquid generated in the production process, no corrosive gas is generated, and about 4% of material is saved compared with electrolytic cleaning.
This patent fills the gap in domestic technology and protects the company's independent intellectual property rights. It is of great significance to the improvement of the quality of such products, the saving of production costs and environmental protection.
