The furnace door 13 is installed on the connecting rod 12, and the placement rack 15 is installed on the furnace door 13. After the alumina sintering furnace body 3 finishes working, the motor A8 is started Rotating counterclockwise causes the ball nut 10 threadedly mounted on the screw rod 9 to move to the right, and cooperating with the adjusting rod 11 and the connecting rod 12, the furnace door 13 moves to the right and separates from the furnace mouth 4. As the furnace door 13 opens and moves to the right, it also drives the placement rack 15 to move to the right out of the alumina sintering furnace body 3. The motor B18 can be started as needed to rotate the placement rack 15 to a suitable material taking and loading angle. The staff removes the burned material from the placement rack 15, and then puts the material to be burned, starts the motor A8 to rotate clockwise, and moves the placement rack 15 back to the left into the alumina sintering furnace body 3, while making the furnace door 13 tightly against the furnace mouth 4, and then starts the alumina sintering furnace body 3 to run. The furnace door can be opened and closed without the staff manually raising and lowering multiple sets of threaded columns, which reduces the labor intensity of the staff and makes the opening and closing of the furnace door simpler and more convenient. The movable placement rack also facilitates the staff to take and load materials.
