In the actual production process, there are many reasons for the fluctuation of the unloading temperature. For example, 1. The control in the process is not in place, the sintering end point is delayed, and the cooling intensity is not in place; 2. The combustion particle size or quality fluctuates, causing the unloading temperature to fluctuate; 3. There are problems with the accuracy of the hidden fuel metering equipment, and the phenomenon of "coal leakage" occurs. The existence of the above phenomena will cause the unloading temperature to fluctuate. Among them, the above reasons that are easy to cause the fluctuation of the unloading temperature can be avoided as much as possible by strengthening management and emergency handling training for process control problems; the fluctuation of fuel particle size and quality can be reduced to a certain extent through management means; however, some problems of fuel metering equipment are very hidden and not easy to be discovered in time, which will still easily cause the unloading temperature to fluctuate.
