Description

Известна рудовосстановительна  печь, состо ща  из ванны печи, источника тока, электрододержателей и электродов.A well-known ore-reducing furnace consisting of a furnace bath, a current source, electrode holders and electrodes.

Отличительной особенностью предлагаемой печи  вл етс  то, что электрододержатели с электродами установлены неподвижно, а ванна печи выполнена с возможностью перемещени  в вертикальном направлении.A distinctive feature of the proposed furnace is that the electrode holders with the electrodes are fixed and the furnace bath can be moved in the vertical direction.

На чертеже представлена предлагаема  рудовосстановительна  печь.The drawing shows the proposed ore recovery furnace.

В электрододержателе 1 зажимают электрод 2, который через свод печи 3 опускаетс  в ванну 4. Ванна перемещаетс  в вертикальном направлении при помощи .механизма перемещени  5. Питание печи осуществл етс  от трансформатора 6 при помощи токоподводов 7.In the electrode holder 1, the electrode 2 is clamped, which, through the arch of the furnace 3, is lowered into the bath 4. The bath moves in the vertical direction by means of the transfer mechanism 5. The furnace is powered from the transformer 6 by means of the current leads 7.

При подаче напр жени  от источника питани  под каждым электродом 2 при нормальной работе загораетс  электрическа  дуга.When voltage is applied from a power source, an electric arc is ignited below each electrode 2 during normal operation.

При избытке восстановител  увеличиваетс  электропроводность щихты, и дл  сохранени  тока в заданных пределах ванна 4 перемещаетс  вниз, а электроды оказываютс  подн тыми..With an excess of the reducing agent, the electrical conductivity of the solids increases, and in order to maintain the current within the prescribed limits, the bath 4 is moved down and the electrodes are raised.

Дл  Того, чтобы восстановить присадку электродов , необходимо добавить кварцит, благодар  этому уменьщаетс  электропроводность ши.чты, и ванна перемещаетс  вверх. При значительном недостатке восстановител  происходит кварцевание печи. В этом случае ванна перемещаетс  вверх, электроды глубже погружаютс  в шихту. Дл  устранени  закварцевани  добавл ют коксик и некоторое количество стружки. Тем самым выравниваетс  посадка электродов, так как ванна перемещаетс  вниз.In order to restore the addition of electrodes, it is necessary to add quartzite, thereby reducing the electrical conductivity of the shear head, and the bath moves upwards. With a significant shortage of the reductant, quartz furnace is produced. In this case, the bath moves upwards, the electrodes are plunged deeper into the charge. To eliminate the quartz, coking and some chips are added. This aligns the seating of the electrodes as the bath moves down.
