Example Embodiment
[0012] A method for controlling the temperature of a heat treatment furnace of the present invention is that when the ambient temperature changes, before the workpiece to be processed is heat treated, the measurement and control instrument 2 in the original measurement and control system is first corrected, and then the original measurement and control system is used to heat the heat treatment The furnace performs temperature control, and the environmental temperature change value that needs to be corrected is determined according to the process specified temperature range of the workpiece to be processed, that is, the larger the process specified temperature range, the greater the environmental temperature change value that needs to be corrected, otherwise the smaller.
[0013] The specific two steps for correcting the measurement and control instrument in the original measurement and control system are as follows:
[0014] 1) A monitoring system is added on the basis of the origin...
