Controller is respectively compared N number of first temperature, the target temperature and initial temperature of pedestal, if the first temperature of cooling piece is in just
Between beginning temperature and the target temperature of pedestal, controller sends instruction, controls the cooling piece to work on；If the first of cooling piece
Temperature is equal to the target temperature of pedestal or the scope between initial temperature and the target temperature of pedestal, controller send finger
Order, controls the cooling piece to be stopped.
8. the temprature control method of constant-temperature metal bath according to claim 1, it is characterised in that the step C is specially：
Controller is respectively compared N number of first temperature, the target temperature and initial temperature of pedestal, if the first temperature of cooling piece is beyond just
Scope between beginning temperature and the target temperature of pedestal, controller send instruction, control the cooling piece by with work at present mode
Opposite form work.
9. the temprature control method of the constant-temperature metal bath according to claim 5 or 6, it is characterised in that the step C is also wrapped
Include：The cooling piece that first temperature of definition cooling piece is between initial temperature and the target temperature of pedestal is to treat regulation and control refrigeration
Piece, further each the first temperature of cooling piece to be regulated and controled of controller, sends instruction and improves the relatively low cooling piece of the first temperature
Operating power, and/or reduce the operating power of the higher cooling piece of the first temperature.
10. the temprature control method of constant-temperature metal bath according to claim 1, it is characterised in that the cooling piece is direct
It is fitted in base bottom or is connected by heat-conducting layer with pedestal.
