Description

Изобретение относитс  к области цветной металлургии. в частности к способам рафинировани  иThis invention relates to the field of non-ferrous metallurgy. in particular to methods of refining and

Известен способ рафинировани  ыеди, включающий продувку кислородом .There is a known method of refining the exit, which includes purging with oxygen.

По предложенному способу продувку кислородом ведут в вакууме и раскисл ют медь углеродсодержащим материалом, что позвол ет удалить газы, летучие и неметаллические примеси.According to the proposed method, oxygen purging is carried out in vacuum and copper is deoxidized with carbon-containing material, which allows to remove gases, volatile and non-metallic impurities.

Способ осуществл ют следующим образом.The method is carried out as follows.

Продувку кислородом П роизвод т при температуре |IQO-l5000C и остаточном давлении I03:-I0 2 мм рт.от. Образующиес  окислы меди восстанавливают твердым углеродом. При этих услови х по всеи поверх-„ ности раздела фаз: жидкий металл твердый углерод образуютс  пузырьш окиси-углерода СО, которые,всплыва , создают кипение распла:ва7 прокачивают его и увлекают на поверхность раздела фаз: металл-ваг куум, остаточные газы,примеси иOxygen purge Produce at temperature | IQO-l5000C and residual pressure I03: -I0 2 mm Hg. The resulting copper oxides are reduced by solid carbon. Under these conditions, across the interface of the phase: liquid metal solid carbon, a carbon monoxide bubble of CO forms, which, after floating up, creates a melt boiling: wa7 pump it over and drag it to the surface of the phase separation: metal-gas, residual gases, impurities and

неметаллические включени , летучие 5 из которых непрерывно удал ют вакуумной откачкой. Окончательное восстановление окислов меди производ т после прекращени  продувкиг выдержкой расплава в вакууме iO - 10 мм рт.ст. и температуре 1350 ,145р°С.non-metallic inclusions, the volatile 5 of which are continuously removed by vacuum pumping. The final reduction of copper oxides is carried out after cessation of purging by holding the melt under vacuum iO - 10 mm Hg. and a temperature of 1350, 145r ° C.

15ПРЕДМЕТ ИЗОБРЕТЕНИЯ 15 SUBJECT OF INVENTION

Способ рафинировани  меди, . включавщий продувку кислородом, отличающийс  тем, что, 20 с целью удаленил газов, летучих и неметаллических примесей, цродувку кислородом ведут в вакууме и раокио л ют медь углеродеодержащим материалом .Copper refining process. including purging with oxygen, characterized in that, in order to remove gases, volatile and non-metallic impurities, oxygen is blown in vacuum and copper is removed by carbon-containing material.
