| 摘 要： | 合理配加热装铁水及DRI，使得冶炼的ER50—6焊丝钢残余Cu控制在0．10％以下，通过采取严格控制电炉、LF精炼和连铸控氮措施后，显著地降低了ER50—6焊丝钢中的氮含量，使得成品的氮含量达到70×10^-6以下。大大改善了该钢种的拉拔性能，基本满足了用户使用该钢种不经热处理直接拉拔成直径0．8～1．2mm细焊丝的要求。

| Abstract: | We properly controlled the harmfull-element copper under 0.10% after charging hot metal and DRI by taking the measure of controlling EF, LF and continuous cast to reduce the N]. The amount of N] in the wire has been less than 70 × 10^-6, by which improved the quailty of the welding wire steel ER50-6 in a 70t mini-line. |
