Metal wire thermal treatment surface oxidation resistance method

Abstract

The invention discloses a metal wire thermal treatment surface oxidation resistance method. The method includes the following steps that (1) a container and a cotton ball are prepared, ethyl alcohol is then poured into the container or water and ethyl alcohol are poured into the container in a certain proportion, and the cotton ball is immersed in liquid of the container; (2) the temperature of a tube heating furnace is adjusted to 820-890 DEG C, a metal wire to be thermally treated moves in the tube heating furnace at a certain speed continuously, and meanwhile the wetted cotton ball extracted from the container is used for wiping the metal wire at a metal wire furnace feed tube opening; alternatively, production is conducted through the metal wire thermal treatment surface oxidation resistance method in the mode that mixed liquid of ethyl alcohol and water is injected along with a metal wire. No protective gas needs to be added in the thermal treatment process, no surface grinding processing is needed after thermal treatment, the surface cleanliness of the metal wire is greatly improved, and production efficiency of the metal wire is improved while the quality of the metal wire is guaranteed.

Description

technical field [0001] The invention relates to a surface oxidation resistance method, in particular to a metal wire heat treatment surface oxidation resistance method. Background technique [0002] After the metal wire is heat-treated, a layer of oxide film is often formed on the surface of the metal wire, so that the surface of the metal wire is not bright and cannot meet the customer's requirements. At present, three methods are often used to deal with this phenomenon. The first method is not to take anti-oxidation measures when the metal wire is heat treated, but to use mechanical methods to polish the oxide layer on the surface of the metal wire after heat treatment. Polishing, or electrochemical polishing, this method has the disadvantages of high labor intensity, long processing time, low production efficiency, high cost and environmental pollution, and the surface cleanliness of the treated metal wire is not enough; the second method It adopts hydrogen chlorine or a...

[0002] After the metal wire is heat-treated, a layer of oxide film is often formed on the surface of the metal wire, so that the surface of the metal wire is not bright and cannot meet the customer's requirements

At present, three methods are often used to deal with this phenomenon. The first method is not to take anti-oxidation measures when the metal wire is heat treated, but to use mechanical methods to polish the oxide layer on the surface of the metal wire after heat treatment. Polishing, or electrochemical polishing, this method has the disadvantages of high labor intensity, long processing time, low production efficiency, high cost and environmental pollution, and the surface cleanliness of the treated metal wire is not enough; the second method It adopts hydrogen chlorine or ammonia decomposition reducing gas or inert gas argon protection heat treatment method, the former heat treatment method mostly buys bottled hydrogen, not only high energy consumption, high cost, but also has potential safety hazards, the latter two heat treatment methods are due to equipment investment Large, high cost, only suitable for the production of large-volume products, and there are also potential safety hazards; the third method is vacuum heat treatment, which has complicated equipment and processes, and has the disadvantages of high cost, time-consuming and laborious, and is difficult to adapt to Continuous production of metal wire
