一、前言目前,国内一般钢丝绳用钢多是电炉钢。由于电炉钢中氮含量偏高,生产所用废钢带入有害非金属夹杂物较多,加之目前炉外精炼设备不完善,因此电炉生产钢丝绳钢质量上存在某些缺点,如降低钢的可塑性,多次拉制容易脆断。为此,邯钢试用LD法冶炼65绳钢,这样不仅可以解决钢丝绳钢质量问题,同时也可以解决本厂引进国外高速
First, the preface At present, the domestic steel wire rope is mostly electric steel. Due to the high nitrogen content in EAF steel, the production of scrap used to bring more harmful non-metallic inclusions, combined with the current furnace refining equipment imperfect, so the quality of EAF wire rope production there are some shortcomings, such as reducing the plasticity of steel, and more Times drawn easily fragile. To this end, Handan Iron and Steel trial LD method smelting 65 rope, so that not only can solve the quality problems of wire rope, but also can solve the factory to introduce foreign high-speed
