APPARATUS FOR PREHEATING AND SUPPLYING SCRAPS.

摘要

This apparatus is provided with a throat (38) which has at one end thereof a raw material inlet port (37) connected to a furnace body (2), and which extends in the diagonally upward direction, a heat exchanger (39) formed on the upper side of the other end of the throat (38), a seal unit (42) provided on the upper side of the heat exchanger (39), a raw material supply unit (43) adapted to supply scraps (13) to an upper portion of the seal unit (42), an exhaust duct (53) which is formed at the portion of the heat exchanger (39) which is immediately under the seal unit (42), and which is connected to an exhaust unit (58), and a raw material feed unit (46) provided at the other end of the throat (38) and adapted to send out the scraps (13) in the heat exchanger (39) to the raw material inlet port (37), the scraps being supplied substantially continuously to the furnace body (2) as they are preheated with a high-temperature exhaust gas from the furnace body (2).
