Abstract : effects of mixed re metals on the properties of low oxygen cleaned round copper rods manufactered by continuous casting and rolling were studied . it shows that trace re elements improve not only the elongation of the rods significantly but also the conductivity , meanwhile , reducing the oxygen contents in the material . in consequence , the product grade is raised from grade 2 to grade 1 , and the final products are improved to higher - grade
文摘:研究了混合稀土金属对连铸连轧生产的低氧光亮圆铜杆性能的影响.结果表明，添加微量稀土元素不仅能明显提高材料的延伸率，而且还提高了其导电性能，同时降低了材料中的氧含量，性能指标从原来的2级品上升为1级品，从而提高了最终产品的档次
