Background
The heat treatment furnace for steel rolling radiant tube is mainly used for normalizing and tempering finished plates by burning gas (CO) to make the temperature in a hearth reach a certain value (about 1000 ℃). In the production process, because the difference exists between the design process and the actual working condition, the ignition electrode used by the furnace ignition system has a bending phenomenon until the ignition electrode is finally burnt out after being used, and because the ignition electrode bends, flame signals are gradually weakened or greatly fluctuated, so that flame combustion is interrupted and repeated ignition cannot be carried out, and when the number of the burners which cannot be combusted exceeds more than 20 percent of the total number of the burners, the temperature in the furnace cannot meet the requirements of the normalizing process. Therefore, when the production reaches a certain level, the furnace has to be stopped to replace the ignition electrode. This is saving cost's principle, generally will change the curved ignition electrode of getting off to burn and carry out the alignment restoration, can only change to burning the unable prosthetic ignition electrode such as out, and the blow-out time generally is about 5 days, needs a large amount of manpower and materials moreover, causes very big influence to the production in thermal treatment region.
Because heat treatment production work load is big, blowing out the maintenance all is very urgent under the general condition, and nozzle quantity is big (232 nozzles in 1 stove), the temperature is high, change regional space is narrow and small, and the maintenance person needs to follow the stove tail and inspect the maintenance to the problem nozzle one by one, and the nozzle is dismantled the degree of difficulty greatly, also brings very big degree of difficulty for the workman's operation. In addition, the ignition electrode is made of ceramic heat-resistant alloy, each price is about 900 yuan RMB, according to the situation of nearly two years, 800 yuan × 60 yuan × 12 months =57.6 ten thousand yuan is consumed each year, the yield is affected by maintenance and replacement of the burner, the smooth production is seriously affected, and the improvement is very necessary.
