Continuous scrap feeding into an electric melting furnace (EAF)

摘要

The invention relates to a continuous scrap feeding in an electric furnace (EAF), wherein a channel is provided, which is at a Enderbunden and at its other end a feed device for the scrap, as well as with a suction device for the channeled through the channel, for preheating the scrap serving, exhaust gases from the melting process, which is connected between the two ends of the channel to this, wherein the suction - relative to the total length of the channel - closer to the furnace facing the end of the channel, as the scraping end facing the end. It is provided that the suction device is designed as a single-stage blower whose suction is oriented substantially in the direction of the furnace and that the clear channel cross-section is tuned zwi such the amount of scrap to be supplied that the height of the scrap fill fills the clear cross section as much as possible.
