Problems solved by technology

Core-spun wire products involve the use of many metal particles or powders. Preventing the oxidation of these metal particles or powders is an important means to improve product application effects and save resources. At present, because some active metal materials are easy to oxidize, there is a considerable part of them in the storage process. Part of the metal material is oxidized into metal oxide, which reduces the product use effect, or even loses its function, causing economic losses

Embodiment 1

[0032] Use the atomization method to atomize the mineral oil, using ultrasonic atomization, its power is: 46-52khz, the metal particles or powder of magnesium and calcium from a feed port with an angle of 40-60 degrees (the effect at 56 degrees) The best) enter the atomization box through the baffle, the height of the atomization box is controlled at 400-3000mm, and the time for the metal particles or powder to pass through the oil mist is controlled at 4 seconds, so that the surface of the metal particles or powder ions absorbs a uniform oil film, thereby Make the oil film coverage on the metal surface reach more than 95%. Through the above technologies, the oxide impurities of the final cored wire product can be less than 0.05%.

Embodiment 2

[0034] Use the atomization method to atomize the vegetable oil, adopt the method of compressed air atomization, the pressure is 0.3-0.5MPa, the calcium metal particles enter the atomization box through the baffle plate from a feed port with an angle of 40 degrees, and the atomization box The height is controlled at 3000mm, and the time for metal particles or powder to pass through the oil mist is controlled at 6 seconds, so that the surface layer of metal particles or powder ions absorbs a uniform oil film, so that the oil film coverage on the metal surface reaches more than 95%. Through the above technologies, the oxide impurities of the final cored wire product can be less than 0.05%.

Embodiment 3

[0036] Ultrasonic atomization method is used to atomize mineral oil, its power is: 52khz, aluminum metal powder enters the atomization box through the baffle from a feed port with an angle of 60 degrees, and the height of the atomization box is controlled at 400mm. The time for metal particles or powder to pass through the oil mist is controlled within 1 second, so that a uniform oil film is absorbed on the surface of the metal particles or powder ions, so that the oil film coverage on the metal surface reaches more than 95%. Through the above technologies, the oxide impurities of the final cored wire product can be less than 0.05%.

Abstract

The invention relates to a method for avoiding surface oxidation of metal. The method is to atomize the oil and let the metal surface adsorb the uniform oil slick. By using atomizing technique, the method is simple and improves the atomization effect of the vegetable oil and the mineral oil, therefore, the oil can uniformly cover the metal surface; at the same time, the invention uses low cost products like the vegetable oil or the mineral oil so as to reduce the production cost and raise the safety of the manufactured products.

Description

technical field [0001] In particular the invention relates to a method of preventing oxidation of the metal surface within a cored wire. Background technique [0002] As countries around the world are increasingly concerned about the supply of resources and energy, the effective use of resources has increasingly become the focus of attention. Preventing metal oxidation is a good way to save resources, and it is one of the key points for enterprises to do a good job in energy conservation and consumption reduction. [0003] Core-spun technology is an out-of-furnace refining method that has emerged in recent years, and is widely used in wire feeding technology for modern steel refining and nodular cast iron spheroidization. Core-spun wire products involve the use of many metal particles or powders. Preventing the oxidation of these metal particles or powders is an important means to improve product application effects and save resources. At present, because some active metal m...
