WIPO Patent Application WO/2022/102208
Kind Code:
A1
Abstract:
This melting equipment, for melting metal raw materials by means of an arc formed by passing current through an arc electrode, is provided with: a furnace main body in which the metal raw materials to be melted are charged; a primary preheating chamber which is configured to be capable of storing the metal raw materials and has a charge port for charging the metal raw materials into the furnace main body, and which preheats the metal raw materials by means of an exhaust gas introduced from the furnace main body through the charge port; a pusher which comprises a pressing member and a pressing member drive device which causes the pressing member to reciprocate in the primary preheating chamber, and which presses the metal raw materials from the primary preheating chamber into the furnace main body by moving the pressing member towards the charge port; and a preheating tunnel which is provided with a transport device that is connected to the primary preheating chamber and that horizontally transports the metal raw materials in a position above the bottom edge of the charge port of the primary preheating chamber, and which, by means of the transport device, supplies the metal raw materials to the primary preheating chamber while preheating the metal raw materials by means of the exhaust gas.
