Abstract
An arrangement for preheating scrap includes a scrap treating furnace into which at least one exhaust gas duct from a metallurgical furnace enters. In order to attain a higher efficiency in preheating, the scrap treating furnace has a through chamber for a plurality of adjacently arranged or superposed scrap receiving vessels. Each of these vessels is provided with its own gas inlet opening and with its own gas exit opening. The scrap treating furnace also includes a charging means on one end of the through chamber to receive at least one scrap receiving vessel and a discharging means on the other end of the through chamber to receive at least one scrap receiving vessel. A conveying means for moving the scrap receiving vessels in cycles from the charging means to the discharging means as well as gas conducting means for connecting the gas exit openings with the gas inlet openings of neighboring scrap receiving vessels are arranged within the through chamber.
