Description

Известен способ рафинировани  меди в вакууме , предусматривающий перегрев жидкого металла выше 1400°С при давлении 0,3- 5 мм рт. ст.The known method of copper refining in vacuum involves the overheating of the liquid metal above 1400 ° C at a pressure of 0.3-5 mm Hg. Art.

Отличие предложенного способа заключаетс  в том, что медь нагревают до 1400-1450°С при давлении мм рт. ст., а затем выдерживают при давлении 10 мм рт. ст.The difference of the proposed method lies in the fact that copper is heated to 1400-1450 ° C at a pressure of mm Hg. Art., and then maintained at a pressure of 10 mm Hg. Art.

Зто позвол ет интенсифицировать процесс.This allows to intensify the process.

Сущность способа заключаетс  в следующем .The essence of the method is as follows.

Катодна  медь марки МО или Ml загружаетс  в вакуумную печь и нагреваетс  до температуры 1400-1450°С при давлении пор дка 10 мм рт. ст., а затем выдерживаетс  при данной температуре и давлении пор дка 10 мм рт. ст. Продолжительность процесса рафинировани  меди составл ет 3-3,5 час.Cathode grade MO or Ml is loaded into a vacuum furnace and heated to a temperature of 1400-1450 ° C at a pressure of about 10 mm Hg. and then maintained at this temperature and pressure in the order of 10 mm Hg. Art. The duration of the copper refining process is 3-3.5 hours.

При прин тых услови х проведени  процесса упругость паров меди значительно больше.Under the accepted conditions of the process, the elasticity of copper vapor is much greater.

чем давление газовой фазы, что создает возможность дл  перемешивани  ламинарного поверхностного сло  жидкого металла в вертикальной плоскости и интенсифицирует процессthan the pressure of the gas phase, which creates the possibility for mixing the laminar surface layer of the liquid metal in a vertical plane and intensifies the process

удалени  газов и примесей меди.removal of gases and impurities of copper.

Содержание водорода в меди, выплавленной по указанному способу, составл ет (2-3). 10-5%, кислорода (2-6) 10-4%, а сумма остальных примесей ие превышаетThe hydrogen content in the copper smelted by this method is (2-3). 10-5%, oxygen (2-6) 10-4%, and the sum of the remaining impurities does not exceed

5-10-3%. Скорость процесса рафинировани  увеличиваетс  в 3-5 раз.5-10-3%. The speed of the refining process is increased 3-5 times.

Предмет изобретени Subject invention

Способ рафинировани  меди расплавлением и выдержкой в вакууме, отличающийс  тем, что, с целью интенсификации процесса, медь нагревают до 1400-1450°С при давлении 10-1 мм рт. ст., а затем выдерживают приThe method of refining copper by melting and aging in vacuum, characterized in that, in order to intensify the process, copper is heated to 1400-1450 ° C at a pressure of 10-1 mm Hg. Art., and then maintained at

давлении 10-з мм рт. ст.pressure of 10 mm Hg Art.
