Oxygen-free copper bar is used more in industrial production industry. So what are the characteristics of the Oxygen-free copper bar? This article will introduce the characteristics of oxygen-free copper bar.
1. The more pure
The key to the popularity of non-oxygenated copper commodities is that it is a pure commodity, which is one of the most fundamental reasons why it is warmly welcomed.
2. More beautiful
The appearance of the Oxygen-free copper bar is more beautiful, more eye-catching, everyone can see at a glance, although its small size, but this does not harm everyone to its appearance beautiful comment, which is also a more beneficial element.
Because the Oxygen-free copper bar is made of red copper with very high purity, the purity of oxygen free copper is 99.95%, and the oxygen content should be < 10ppm, residue composition to < 0.05%. The raw materials meet the requirements, after a time of drawing and rolling, and then measure their symmetry, after reaching the standard, cut into the necessary specifications, and then after mechanical equipment peeling and polishing, they become finished products. The oxygen content of such an Oxygen-free copper bar is very symmetrical, very small relative standard deviation. And the surface is clean and clean, easy to use, low price.
Oxygen-free copper bar is generally used in power engineering, communication and electromagnetic induction and other manufacturing industries, and the working temperature of this component is high.
type
The Oxygen-free copper bar should be divided into general Oxygen-free copper bar and high purity oxygen free copper rod. General oxygen free copper rod in DC transformer core induction furnace smelting, high purity oxygen free copper rod smelting in vacuum pump induction furnace.
High quality cathode copper shall be used as raw material for smelting Oxygen-free copper bars. High purity cathode copper shall be used as raw material for high purity oxygen free copper rod.
Characteristics and application fields
High purity, conductivity, heat transfer is very good, production and processing characteristics and welding, corrosion resistance, corrosion resistance are good.
Smelting way
Generally, when the semi-continuous forging method is used for the Oxygen-free copper bar, the whole process of the refining of the solution in the melting furnace and the holding furnace can be done without time constraint. Continuous forging is different. The quality of liquid copper not only depends on the refining quality of the melting furnace and the holding furnace, but also depends on the reliability of all the system software and the whole process.
High quality Oxygen-free copper bar selection of vacuum pump smelting, vacuum pump smelting can not only make the oxygen content is greatly reduced, but also can make some residue composition greatly reduced.
