Abstract
The invention provides a method for full closed-loop controlling an electric upsetting temperature, wherein a highest temperature value allowed in an electric upsetting process is set in a temperature controller; when the electric upsetting temperature measured by a colorimetric infrared thermometer is less than a set temperature, an input signal of a power regulator is given by a microcomputer or other voltage giving devices; the heating in the electric upsetting process is not influenced by the temperature controller; when the electric upsetting temperature measured by the colorimetric infrared thermometer exceeds a set value of the temperature controller or the electric upsetting temperature rises too fast, the temperature controller performs control and mathematical operation according to a given cooling control manner and a set proportion integration differentiation (PID) parameter, and outputs a current signal to be overlaid on the power regulator; the phase of the current signal is opposite to the phase of an given signal of the microcomputer or the other voltage giving devices, and the current signal neutralizes a part of an input signal given to the power regulator by the microcomputer or the other voltage giving devices, namely cooling is performed, therefore the electric upsetting temperature is reduced or the rising speed of the electric upsetting temperature is slowed so as to achieve an aim that temperature is closed-loop controlled to limit the highest temperature.
