摘要: The invention relates to a method for cleaning slag, created in metallurgical processes of non-ferrous metals, in an electric furnace, and particularly the method is related to a semi-continuous cleaning process. According to the novel method, the electric furnace is provided with at least two slag tapping holes, the lower of which is arranged on the same level as the tap hole in a conventional, batchwise operated furnace, and the second tap hole is located higher up, either at the height of the feed inlet or only slightly underneath it.
