The electric heating block 7 heats the air in the sintering area 22, and the formed hot air flows to the preheating area 21 through the box body 2 and the heat collecting pipe 12 to preheat the magnetic tiles. After the preheating processing of the magnetic shoe is completed, the motor 4 drives the feed roller 3 to rotate through the speed reducer 44 and the rotating rod 41, and the heat-resistant plate 5 is conveyed to the sintering area 22 to sinter and process the preheated magnetic shoe. At this time, the baffle 61 separates the sintering area 22 from the cooling area 23, so that the possibility that hot air in the sintering area 22 enters the cooling area 23 to increase the temperature in the cooling area 23 is reduced, and the sealing strip 66 blocks the hot air in the box body 2, so that the possibility that the hot air leaks out of the box body 2 to influence the stability of the temperature in the sintering area 22 is reduced.

After the sintering process of the magnetic shoe is completed, the output end of the air cylinder 65 is extended, so that the baffle 61 moves upward in the vertical direction, the sintering area 22 and the cooling area 23 are communicated, and the feed roller 3 feeds the heat-resistant plate 5 to the cooling area 23. At this time, the water pump 9 drives the cooling liquid to circulate between the water tank 8 and the cooling pipe 10, and absorbs the heat emitted by the magnetic shoe, so that the magnetic shoe is cooled. After the magnetic shoe is cooled to room temperature, the operator opens the isolating door 24 at the discharge port to take out the heat-resistant plate and the magnetic shoe. Because the preheating processing and the cooling processing of the magnetic shoe are respectively carried out at the two ends of the box body 2, and different media are used, the interference between the preheating processing and the cooling processing is reduced, and the possibility that the processing efficiency of the magnetic shoe is influenced is reduced.
