以简便、易行为原则，研究开发了一种钢液脱铜新方法—铵盐法，所用脱铜剂为氯化铵、草酸铵和尿素，加入方式为仿喂丝法和喂丝法－ 结果表明，铵盐法具有较好的脱铜效果，其中氯化铵脱铜效果最好，脱铜率达到了３６－３６％ ，单位质量（克） 脱铜剂可脱除０－６９ ｇ 以上的铜－ 将钢中ｗ （Ｃｕ） ＝ ０－６０％ 降至ｗ （Ｃｕ） ＝ ０－３ ％ 只需加入４－５ ｋｇ／ｔ左右的脱铜剂，在工业上有较好的应用前景
Based on the principle of simplicity and easiness, a new method of copper de-copperization was studied and developed - ammonium salt method, ammonium chloride, ammonium oxalate and urea were used as the decalcifying agent, and the adding method was imitation-feeding method and feeding-feeding method It shows that the ammonium salt method has a better copper removal effect, of which the best removal of ammonium chloride of copper, copper removal rate reached 36-36%, unit mass (g) of copper removal agent can be more than 0-69 g Copper - Reducing w (Cu) = 0-60% in steel to w (Cu) = 0-3% Simply adding a copper removal agent of 4-5 kg / t or so has a good application prospect in industry
