| Abstract: | 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. |
