Abstract

PURPOSE:To repair the vacuum tank with excellent working efficiency and safety, at repairing the vacuum tank of the degassing apparatus for the molten steel, by moving only the vacuum tank to the repair shop using the truck provided with the lift, by temporarily placing the vacuum tank on the stationary bench, and by arranging the repair tools at necessary positions using the truck. CONSTITUTION:The vacuum tank 9 for degassing the molten steel is detached from the auxiliary apparatus and is placed on the lift 2 of the truck 1, and then, the truck 1 is moved to the stationary bench 4 at the repair shop owing to the driving device 3. The lift 2 is actuated for temporarily placing the vacuum tank 9 on the bench 4 through the hydraulic jack 5. After that the truck 1 is moved, and the jigs like as the preheating hood 6, etc., necessary for repairs, are placed and held on the lift 2 by the crane, etc., and then, truck 1 is moved to the position under the vacuum tank 9. Hereupon, the hydraulic jack 5 and the lift 2 are adjusted not to cause the jig to interfere with the bottom of the vacuum tank 9. Under this condition, the repair of the vacuum tank 9 is worked safely and efficiently.
