摘要
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。
A new technique of removing copper is investigated and studied in molten steel by ammonium salt.Experiments are carried out with agents of NH 4Cl,(NH 4) 2C 2O 4 and CO(NH 2) 2 by feeding wires and simulating feeding wires.Results indicate that NH 4Cl has the best result, i.e,efficiency of removing copper is 36 36%,the amount of decopperization with per gram of copper removing agents is 0.69g by simulating feeding wires in induction furnace,and the content of copper in molten steel can be reduced from 0.60% to 0.30% with 4.5 kg/t agents.This technique has a much better prospect in the industry.
