摘　　要：详细分析了ER70S-6生产过程中各工序氮含量的变化。探讨转炉、LF炉、连铸工序中的增氮原理,并结合唐钢二钢轧厂生产实践,提出降低ER70S-6CO2气保焊丝钢氮含量的工艺措施。The change of nitrogen content in various steps for ER70S - 6CO2 welding wire is analysed in detail. The principles of increasing nitrogen in converter,LF furnace and continuous casting process are discussed. Process measures are put forward to reduce nitrogen content of ERTOS - 6CO2 gas shielded welding wire steel combining the production practice of NO. 2 Steel Making and Rolling Plant of Tang Steel.
