一种新型埋弧堆焊用药芯焊丝的研制

摘要

According to the technical requirements,operating conditions and wear condition of the continuous casting equipment like pulling-straightening rollers in iron &steel plants,a new flux-cored wire for submerged-arc welding was developed and its performance and metallurgical structure were analyzed.%根据钢厂连铸拉矫辊及扇形段辊等连铸设备的技术要求、工作条件和磨损状况，开发了一种金属粉芯的埋弧堆焊药芯焊丝，并对其性能和焊缝金相组织进行了分析。
