Embodiment 1
[0016] Motor core heat treatment process, the heat treatment equipment includes annealing furnace, DX generation furnace, the specific steps
[0017] The steps are: (The following parameters are set using the commonly used chain heat treatment furnace as an example)
[0018] 1. Turn on the annealing furnace and raise the temperature to remove moisture.
[0019] 2. Set process parameters:
[0020] Annealing furnace temperature (first stage) 720°C; annealing furnace temperature (second stage) 770°C; annealing furnace temperature (third stage) 780°C; annealing furnace temperature (fourth stage) 780°C; annealing furnace temperature (fifth stage) 730°C; The temperature in the chemical zone is 720°C; the temperature in the cooling zone (first stage) is 680°C; the temperature in the cooling zone (second stage) is 560°C; the temperature in the cooling zone (third stage) is 480°C;
[0021] 3. The DX generating furnace ignites and passes DX gas. When the temperature in the annealing ...
Embodiment 2
[0029] This embodiment is basically the same as Embodiment 1, the difference is that the process parameters are set differently, and the process parameters in this embodiment are set as: annealing furnace temperature (one stage) 700°C; annealing furnace temperature (second stage) 750°C ;Annealing furnace temperature (three sections) 760°C; annealing furnace temperature (four sections) 760°C; annealing furnace temperature (five sections) 710°C; (Second section) 540°C; cooling zone temperature (third section) 460°C; mesh belt speed: 50-55mm / min.
[0030] Other parts of this embodiment are the same as those of Embodiment 1, and will not be repeated here.
Embodiment 3
[0032] This embodiment is basically the same as Embodiment 1, except that the process parameters are set differently. The process parameters in this embodiment are set as: annealing furnace temperature (first stage) 740°C; annealing furnace temperature (second stage) 790°C ;Annealing furnace temperature (three sections) 800°C; annealing furnace temperature (four sections) 800°C; annealing furnace temperature (five sections) 750°C; (second stage) 560°C; cooling zone temperature (third stage) 500°C; mesh belt speed: 50-55mm / min.
[0033] Other parts of this embodiment are the same as those of Embodiment 1, and will not be repeated here.
