Problems solved by technology

Metal wires belong to long products and cannot be produced in sections. The key to the production technology of plasma surface metallurgy metal wires is to make them form a continuous process of plasma surface metallurgy and achieve the ability of large-scale production. At present, the technology and equipment based on plate production are not enough. Plasma surface metallurgical treatment suitable for metal wire
Therefore, although there are already a large number of patent applications and research reports on double-layer glow plasma surface metallurgy technology, the current technology development and implementation status are not consistent with the application of plasma surface metallurgy metal wire production technology in actual production and reaching a certain level of industrialization. There is still a long way to go

Description

technical field [0001] The invention relates to a production method and device for plasma surface metallurgy wire, belonging to the field of metal wire surface metallurgy. Background technique [0002] Wire rod is an important variety of steel materials. In 2006, China's wire rod output reached 71.51 million tons, accounting for 17% of steel output. It is widely used in various aspects of people's production and life. [0003] Metal corrosion is a phenomenon in which metals are destroyed by chemical or electrochemical reactions with the surrounding environment. Wire rods also suffer from serious corrosion problems. Due to the corrosion of metal wires, structural collapse, equipment failure, and pollution of daily necessities often occur, seriously affecting people's normal production and life; such as the corrosion of building steel bars, causing hidden dangers to buildings, highways, and coastal projects; steel cables and steel strands Corrosion poses a serious threat to ...
