Standard temperature: The temperature in standard channels should be 20°C higher than the standard value; the temperature in non-standard channels should be 20°C higher than the specified level. If the overall temperature of the oven is too low, it indicates that the temperature of individual horizontal channels or individual channels themselves is low. At 24 hours, the temperature should be between 1290–1300°C. In this case, shut down 1/3 of the valves associated with that channel, insert a wire into the orifice plate of that channel, increase the suction force in the flue by 5 Pa, replace the orifice plate, and clean the nozzles. At 26 hours, the temperature should be between 1280–1290°C; check the suction force of that channel and increase the pressure in the main gas pipeline by 200 Pa to adjust the suction force of that channel. Repair the bricks in the gas channels. At 28 hours, the temperature should be between 1260–1270°C; check the resistance in the horizontal tubes and inspect the inclined channels. At 32 hours, the temperature should be between 1220–1230°C; clean the tar from the valves. At 36 hours, the temperature should be between 1210–1220°C. These are the procedures for managing the temperature of horizontal channels, developed by Li, the deputy plant manager in charge of processes at Shanxi Yangguang Huatai Coking Plant. Please take a look. This deputy factory manager insisted on simplifying the procedures for adjusting temperatures further and further, asking his subordinates to use just three or five words to describe these procedures instead of writing several sentences. To this end, he created a table using horizontal temperature management operations as an example; others said there were too many errors in it, but he refused to admit it. What should be done?
It is recommended that in such situations, if one is not entirely confident in being able to persuade the other party, it is best to wait and see how things develop. If there is a certain degree of danger, it is best to use other methods to avoid that principle. As for this type of operational control, the operating conditions are determined based on different raw materials. According to his approach, each attempt, whether it works or not, is also an opportunity to learn. The way the problem is described already reveals disapproval of this superior leader. It should be about the matter itself rather than the person involved; it’s not necessarily true that what others say is wrong – time will show what happens. These are just personal opinions for reference only.
Under no circumstances should you learn from *, as most of the things produced by this deputy manager are incorrect. For example, if the standard flue temperature is 20°C higher than the standard value, yet the valve is closed by 1/3 – it’s obvious that something is wrong. This is the temperature in the horizontal direction; only the temperature of the standard flame channel is high, while the temperatures of the other channels are not. Why close the valve? Just add iron bars at the standard eyelet plate, right? Besides, what exactly causes such high temperatures? A leakage in the furnace wall of a regenerative furnace can also lead to high temperatures……
