step two: when the temperature in the heating furnace body (6) rises to a specified temperature, opening a sealing door (13) of the heating furnace body (6), placing workpieces to be subjected to heat treatment in the same batch on a movable supporting plate (2) positioned in a heating chamber (27), then closing the sealing door (13), and setting related time parameters for the heating furnace through an operation keyboard (20);
step three: placing the next batch of workpieces to be heat-treated on the movable supporting plate (2) at the upper part or the lower part of the heating furnace body (6);
step four: after the set time is reached, the AVR central control processor controls a second driving motor (10) fixed on the back surface of the heating furnace body (6) to rotate, and a transmission gear (11) is meshed with rack plates (22) on the side walls of an upper sliding plate (16) and a lower sliding plate (21) for transmission, so that the upper sliding plate (16) and the lower sliding plate (21) are driven to move outwards, and supporting plate movable holes (15) on the top surface and the bottom surface of the heating furnace body (6) are opened;
step five: when the supporting plate movable hole (15) is completely opened, the AVR central control processor controls the first driving motor (3) to work to drive the screw rod (9) to rotate, the outer wall of the screw rod (9) is in screwing connection with the threaded hole (26) in the movable supporting plate (2) in the rotating process, so that the movable supporting plate (2) is driven to correspondingly move up and down, the heat-treated workpiece in the heating bin (27) is moved to the outside of the heating bin (27), and meanwhile, the heat-treated workpiece in the next batch is moved to the inside of the heating bin (27);
step six: after the next batch of heat-treated workpieces move to the designated position of the heating bin (27), the AVR central control processor controls the second driving motor (10) fixed on the back of the heating furnace body (6) to rotate, so as to drive the upper sliding plate (16) and the lower sliding plate (21) to move inwards, and further close the supporting plate moving holes (15) on the top surface and the bottom surface of the heating furnace body (6);
step seven: and taking down the heat treatment workpiece on the movable supporting plate (2) outside the heating furnace body (6).
