紫杂铜中杂质行为的研究

Research on the Impurity Behaviour of the Red Impure Copper

采用喷射冶金技术，讨论了紫杂铜中杂质总量对铜延伸率和电阻率的影响规律，分析了工艺因素对杂质去除的影响，给出了铜液中杂质去除的速度，确定了铜液中杂质去除的工艺要点，使电工用铜Ｔ２黑杆超过了ＧＢ３９５２－８３ＩＥＣ２８标准。

Abstract Applying the jet metallurgy technique, the paper makes a discussion of the affecting regulation upon this kind of copper ′s coefficient of elongation and the specific resistance in response to the total amount of the foresign substance existing in the red impure copper. In addition, the paper also gives an analysis of all the technique factors affecting the impurity removal, proposes the removing speed of molten copper, definites all key points for removing impurities in the liquid copper. As a result, the blacken rod exceeds the standard of GB3952-83 ICE28 concerned with the copper T 2 in electriccal engineering.
