When the titanium alloy rod 4 passes between the two front sensors 103, the front sensor 103 detects the titanium alloy rod 4 and controls the door closing electric cylinder 202 close to the side of the front sensor 103 to extend, thereby driving the lifting plate 203, the lifting column 204 and the door panel 205 to rise, and the titanium alloy rod 4 enters the heating furnace body 201, and then enters the furnace cover 206. After the titanium alloy rod 4 enters the heating furnace body 201, the door closing electric cylinder 202 contracts, so that the door panel 205 is closed, so that the heating furnace body 201 is closed, and the titanium alloy rod 4 is induction heated by the induction coil 207. When the titanium alloy rod 4 moves between the two rear sensors 104, the rear sensor 104 detects the titanium alloy rod 4 and controls the door closing electric cylinder 202 close to the side of the rear sensor 104 to extend, thereby driving the lifting plate 203, the lifting column 204 and the door panel 205 to rise, and the titanium alloy rod 4 leaves the heating furnace body 201. Similarly, the rotation of the rear eccentric wheel 118 will drive the lifting and lowering tooth plate 308 of the loading and unloading mechanism located on one side of the rear eccentric wheel 118 to move up and down through the cooperation between the rear eccentric column 119 and the sliding groove of the transverse groove rod 303, thereby realizing the discharge of materials.
