Abstract
PURPOSE: To repair the portion alone which must be mended with a little dust formation, by air-cooling the internal wall of a mixer car, by removing adhered material such as slag with spray of high press. water, by digging a slag line portion of the internal wall corresponding to that most heavily melted, then by repairing the portion.
CONSTITUTION: A mixer car 1, refractory lining of which has been melted, is allowed to stand so as to cool the inside naturally. The mixer car is laid down, and the inside is compulsively air-cooled by a fan through a cast iron inlet 4 and a lance hole 5. When it is cooled enough for workers to enter the car 1, the car 1 is turned upside down so that the cast iron inlet 4 is directed downward. Pressurized water is sprayed through a nozzle 8 to the portion, where graphite, slag, or unreacted desulfurizing agent 7 are adhered to the inside lining, in order to remove the adhered material. Then the lining of a portion 9 where melting is caused most heavily is digged by an excavator 10 while spraying water downward with formation of a little dust. The portion is repaired by lining with heat resistant lining material. The other portion with comparatively small damage is used once again without being mended, thus improving the repairment efficiency.
