The invention discloses a grate machine grate temperature field indirect monitoring method and a device thereof in a grate machine rotary kiln cold ring pelletizing process, and relates to the technical field of metallurgical industry measurement and control. The temperature field of the invention the thermocouple temperature sensor on the chain grate bed 4 section area for indirect detection, and so the ventilation quantity real-time adjustment of different regions of the drum / exhaust box, realize the indirect control of chain grate bed temperature. It is characterized in that: the grate bed temperature field indirect detection and control technology, the device is stable and reliable, has overcome the human caused by the chain grate bed temperature fluctuations, improve the pellet quality; design of signal acquisition, temperature field calculation and dead zone, disturbance feedforward PID control algorithm software program, realize the pellet the chain grate machine normal operation at the optimum temperature, can prolong the grate of key parts of the thermal fatigue life of 2 to 3 years; based on the image design of man-machine interface configuration software technology is intuitive, simple operation.
