Description
Дл цементации меди из раствора требуетс губчатое железо, отличающеес высокой реакциоцной способностью.Cementation of copper from solution requires sponge iron, which has a high reactivity.
Предлагаемый способ заключаетс в том, что губчатое железо получают пр мым восстановлением руды твердым восстановителем. Восстановитель берут в большом избытке против теоретически необходимого (отношение количества руды к количеству восстановител 1:1-7-2). Наличие большого количества твердого восстановител в шихте не дает возможности частицам восстановленного железа спекатьс и укрупн тьс . Крупность восстановител должна быть несколько меньше крупности руды, чтобы не было сегрегации шихты.The proposed method is that sponge iron is obtained by direct reduction of the ore with a solid reducing agent. The reducing agent is taken in large excess against the theoretically necessary (the ratio of the amount of ore to the amount of reducing agent is 1: 1-7-2). The presence of a large amount of solid reducing agent in the mixture makes it impossible for the reduced iron particles to agglomerate and coarsen. The fineness of the reducing agent should be somewhat smaller than the ore size so that there is no segregation of the charge.
В качестве восстановителей можно использовать антрацит и некоксуюЕциес каменные угли с умеренным содержанием летучих. Дл получени сильно развитой поверхности губки процесс ведут при возможно более низкой температуре и за возможно более короткий срок. Дл этого шихту равномерно нагревают и энергично перемешивают в процессе восстановлени .Anthracite and non-coking Eties coals with moderate volatile content can be used as reducing agents. To obtain a highly developed surface of the sponge, the process is carried out at the lowest possible temperature and in the shortest possible time. For this, the mixture is heated uniformly and vigorously stirred during the reduction process.
Дл осуществлени способа предлагаетс использовать механическую многоподовую печь, снабженную муфельными подами.To implement the method, it is proposed to use a mechanical multi-stage furnace equipped with muffle hearths.
На чертеже изображена схема печн.The drawing shows a diagram of the furnace.
В муфел х сжигаетс газ, который образуетс в печи в процессе восстановлени руды твердым углеродом. Тепла, получающегос от сгорани этих газов, вполне достаточно дл поддержани в печи необходимой температуры. Количество газа регулируетс путем подачи в лечь воздуха. Тепло отход щих газов муфельных подов используетс дл подогрева исходной шихты.The muffles burn the gas that is formed in the furnace during the process of reducing the ore with solid carbon. The heat resulting from the combustion of these gases is sufficient to maintain the required temperature in the furnace. The amount of gas is regulated by injecting air into the bed. The heat of the waste gases of the muffle sweatsheets is used to preheat the initial charge.
