Melt metallurgical installation comprising a charging element

摘要

A melt metallurgical installation has a melting furnace for melting scrap metal and a charging region for the melting furnace which is located above the melting furnace. The installation further has a charging element, which has been filled with scrap metal intended for the melting furnace and can be moved in a movement direction into the charging region where it can be emptied and then moved again, in the empty state, against the movement direction out of the charging region. The charging region is enclosed by a hood such that the charging region, including the charging element which has been placed in the charging region, is closed at the top and on the sides. The hood has at least one upper extraction opening through which the waste gases and dust developing in the hood can be extracted out of the hood.

主权项

1. A method for controlling an installation comprising:
charging scrap metal into a melting furnace from a charging region above the melting furnace, the melting furnace being charged via a chute, the chute preheating the scrap metal, the chute having upper and lower closure elements, the upper closure element being at an upper end of the chute, away from the melting furnace, the upper closure element being opened for conveying the scrap metal into the chute and then closed, the lower closure element being at a lower end of the chute, toward the melting furnace, the lower closure element being opened for loading scrap metal from the chute into the melting furnace and then closed; using a charging element to move the scrap metal in a movement direction toward the charging region where the scrap metal can be emptied into the chute before the charging element is moved in a direction opposite to the movement direction, away from the charging region; using a hood to at least partially enclose the charging region, such that when charging element is in the charging region, the hood encloses a top end of the charging element opposite the melting furnace and sides of the charging element, the hood having at least one upper extraction opening; using an extraction system to extract waste gases and dust out of the hood via the upper extraction opening; and controlling the extraction system such that extraction is coordinated with opening and closing of the upper closure element and/or conveyance of the scrap metal to the chute.
