Abstract

See full text

A continuous scrap feed into an electric smelting furnace (EAF) having a channel connected at one end to an opening in a wall of the smelting furnace and has at its other end a charging device for the scrap. An extraction device for the off-gases which are guided through the channel serve to preheat the scrap, this extraction device being connected to the channel between the two ends of the channel located closer to the smelting furnace than the scrap feed in relation to the total length of the channel. The extraction device is a single-stage blower whose intake opening is oriented in the direction of the smelting furnace, and the clear cross section of the channel between the extraction device and the scrap feed is adapted to the amount of scrap so that the height of the scrap charge substantially fills the clear cross section.
