When using hot-blast stove, it is likely to be affected by equipment problems and sudden changes of external factors. It is not helpful to take effective measures in time for the operation of hot-blast stove, which results in abnormal temperature of hot-blast stove. If the temperature of hot-blast stove is cooler. How should we solve it? If the temperature of hot blast stove is cooler, it may be because the weighing failure of feeding system appears inaccurate feeding and the discovery is not timely. If the effect can not be solved after taking measures, it may cause abnormal furnace condition or the freezing accident of hearth. At this time, we need to take the following measures decisively:
1. The operation in the hot blast stove first needs to reduce the air by about 50%, control the material speed, and prevent the furnace temperature from becoming cooler.
2. Adding batches of net coke while reducing air flow, and reducing coke load accordingly.
3. Organize all efforts to get rid of the slag iron before the furnace, try to avoid the occurrence of tuyere edge irrigation and burnout accidents, and wait for the net coke to be delivered.
4. Ensure that the wind pressure and air volume are symmetrical and avoid collapse and suspension.
If there are problems in using hot stove, we need to shut down the stove in time to find out the reasons, and then take corresponding solutions.
Above all, this is a brief introduction to the factors and solutions of the cooling of hot stove temperature.
