[0033] The circuits, electronic components and module structures involved all adopt existing technologies, which can be fully implemented by those skilled in the art. Needless to say, the content protected by this application does not involve improvements to software, circuits and methods.

[0034] Working principle: When in use, first turn on the power, place the workpiece to be processed on the trolley 2, and start the electric heating plate 22 through the control panel 31 to heat the workpiece. At the same time, start the fan 41 through the control panel 31. The fan 41 draws air from the top of the resistance furnace 1 and transports it to the resistance furnace 1 through the conveying pipe 4, thereby accelerating the air convection in the resistance furnace 1 and reducing the temperature difference. Multiple temperature sensors 3 monitor the temperature in the resistance furnace 1 in real time and feed the data back to the control panel 31. When the temperature deviates from the required temperature, the control panel 31 will automatically adjust the power of the electric heating plate 22 or start / turn off the fan 41 to keep the temperature in the resistance furnace 1 constant.

[0035] When it is necessary to take the workpiece, start the adjusting motor 7, which drives the lead screw 71 to rotate and controls the lifting plate 62 to slide downward along the guide column 61. The lifting plate 62 pulls the door panel 5 upward through the steel cable 66. At the same time, the design of the movable pulley 65 and the fixed pulley 63 can save effort. When the door panel 5 is fully opened, the trolley 2 can be easily pushed in and out of the resistance furnace 1.
