Известно применение дл продувки шлаков природного газа вместо пылевидного угл горючих газов.Known use for purging the slag of natural gas instead of pulverized coal combustible gases.
Предлагаемый способ отличаетс тем, что дл извлечени содержащихс в шлаках цветных и редких металлов исходный шлак обрабатывают продувкой расплава продуктами полного или неполного горени горючих газов, предварительно смешанных с воздухом и сожженных вне плавильной камеры нечн. Температура шлаковой ванны поддерживаетс посто нной за счет тепла от сжигани горючих газов.The proposed method is characterized in that in order to extract the non-ferrous and rare metals contained in the slags, the initial slag is treated by blowing the melt with products of complete or incomplete combustion of combustible gases previously mixed with air and burned outside the smelting chamber. The temperature of the slag bath is kept constant by the heat from the combustion of combustible gases.
В результате проведенных испытаний установлено , что за 120 мин продувки жидкого шлака продуктами горени природного газа в смеси с воздухом в расплаве остаетс 1% цинка, 0,05% олова и следы свинца, т. е. значительно меньшее количество указанных металлов , чем в конечных шлаках при фьюминговании .As a result of the tests carried out, it was established that for 120 minutes the purging of liquid slag with products of burning natural gas mixed with air in the melt remains 1% zinc, 0.05% tin and traces of lead, i.e. a much smaller amount of these metals than in the final fouling slags.
Предложенный способ упрош;ает технологическую схему переработки шлаков и ускор ет процесс переработки.The proposed method simplifies the processing scheme of slag processing and speeds up the processing process.
