Description

печи регулируют в пределах 1100-1200 мм. Температуру расплава в зоне отстаивани  поддерживают в интервале 1200-1250° С.furnace regulate in the range of 1100-1200 mm. The temperature of the melt in the settling zone is maintained in the range of 1200-1250 ° C.

После переработки заданного количества шихты черновое олово выпускают в приемную |Ванну. Обедненный в зоне отстаивани  шлак с содержанием 1-5% олова выпускают из электропечи и -направл ют на фьюминговую установку дл  доработки до содержани  в нем не более ОД % олова.After processing a specified amount of the mixture, the rough tin is released into the reception | Bath. The slag depleted in the sedimentation zone with a content of 1-5% tin is discharged from an electric furnace and sent to the fusion plant for processing to contain no more than OD% tin in it.

Предложенный способ обеспечивает повышение производительности на 8-18 г сухого концентрата в сутки, а также снижение расхода энергии на 380-430 кВтч1т и расхода восстановител  на 40-50 кг/т.The proposed method provides an increase in productivity by 8-18 g of dry concentrate per day, as well as a reduction in energy consumption by 380-430 kWh1t and consumption of a reducing agent by 40-50 kg / ton.
