摘　　要：介绍ER50—6焊接用热轧盘条研制过程：合理控制盘条化学成分；冶炼过程控制出钢温度1620—1650℃；连铸时控制过热度15～35℃，正常拉速2．2～2．6m／min；轧制时控制加热温度990～1050℃；控冷时控制吐丝温度820～850℃，辊道入口速度7m／min，以及0．45℃／s的冷却速度。生产的笳．5mmER50—6盘条不经退火处理可直接拉拔成D1．0mm的焊丝半成品，成品焊丝焊接性能良好，飞溅少，焊缝平整美观，质量稳定可靠，满足用户要求。To introduce the development process of ER 50 - 6 welding hot rolled wire rod ： to reasonably control wire rod＇ s chemical composition ; to control tapping temperature at 1 620 -1 050 ℃ during steel smelting, degree of superheat 15 - 35 ℃ during continuous casting, normal drawing speed at 2.2 - 2.6 m/min ; to control heating temperature at 990 - 1 050℃ during rolling; to control wire rod laying temperature at 820 - 850℃, roller bed entrance speed at 7m/min, and cooling rate at 0.45 ℃/s. Diameter 5.5 mm ER 50 - 6 wire rod without annealing can be directly drawn to diameter 1.0 mm welding wire semi-finished product. Finished welding wires work well with few spatter, and weld joint is smooth and quality is stable and reliable, which meet user＇s reuuirement.
