Description
(54) СПОСОБ ОГНЕВОГО РАФИНИРОВАНИЯ ЧЕРНОВОЙ МЕДИ ОТ НРИМЕСЕЙ(54) METHOD FOR FIRE DEFINING BLACK COPPER FROM NRIMES
производ т подгрузку скрапа. Затем в воздушное дутье торцовых горелок подают кислород при обогащении дуть кислородом до 28%. Повышение температуры расплава с 1150 до 1180°С произведено за 12 мип.loading scrap. Then, oxygen is supplied to the air blast of the end burners during enrichment by blowing oxygen up to 28%. The temperature increase of the melt from 1150 to 1180 ° С was made in 12 mip.
Затем снимают вторичный шлак путем подачи его к шлакосъемной машине восстановительной смесью с ,7-0,8. Трубку с 1юсстаиов1Г1ельной смесью вставл ют в жидкий расплав меди и плав щие кучи шлака барбатажем подталкивают к шлакосьемиой . При этом одновременно расплав меди подвергаетс дегазации и восстановлению.,Then, the secondary slag is removed by feeding it to the slag removal machine with a reducing mixture, 7-0.8. A tube with a single mixture is inserted into the liquid copper melt and the melting heaps of slag are pushed to slag and family by barbattage. At the same time, the copper melt undergoes degassing and recovery.
После съема всего вторичного шлака в восстановительной смеси снижают а до 0,35-0,55, чем обеспечивают более быстрое восстановление окислов медн.After the removal of all the secondary slag in the reducing mixture is reduced a to 0.35-0.55, which ensures faster recovery of copper oxides.
По окончании восстановлени ведут розлив анодной меди.At the end of the reduction, anodic copper is bottled.
Общее врем , включа все операции рафинировани и розлив анодной меди, 13 ч 50 мин.Total time, including all refining operations and pouring of copper anodic, 13 h 50 min.
Использование предлагаемого способа огневого рафинировани черновой меди по сравнению с известным снособом позвол ет:The use of the proposed method of fire refining of blister copper as compared with the known method allows:
сократить врем всего процесса до 13 ч 50 мин вместо 16 ч 50 мин, что повысит производительность всего анодного передела;reduce the time of the whole process to 13 h 50 min instead of 16 h 50 min, which will increase the productivity of the entire anodic redistribution;
сократить расход дорогосто щей древесины на дегазацию расплава;reduce the consumption of expensive wood for the degassing of the melt;
снизить расход газа и мазута благодар сокращению времени процесса н совмещени операций съема вторичного шлака, дегазации расплава и восстановлени .to reduce the consumption of gas and fuel oil due to the reduction of the process time and the combination of operations for the removal of secondary slag, degassing of the melt and recovery.
