In iron and steel industry, automation and mechanization of furnace relining work are required as the measures of the environmental betterment therein which is extremely important for ensuring the factors in the future. In this paper, the inductions of the equipment for castable refractory relining at the bottom of the ladle, the equipment for handling slag line bricks of the ladle, the equipment for brick disintegration in the RH-degassing vessel which have been mechanized recently at the Mizushiminduction`s Kawasaki Steel Corporation as a part of the betterment of furnace relining work carried out hitherto are described. The main points of said betterment are indicated hereafter. The equipment for castable refractory relining at the bottom of the ladle is exploited and utilized. The hard works are lightened by the large scale of the bricks for the slag line of the ladle and the induction of the vacuum lifter. The equipment exclusive for disintegration in the RH-degassing vessel is exploited and utilized. Owing to the above-mentioned improvements, 27% and 60% of the operation time are reduced in the relining work for the ladle and disintegration work for the RH-degassing vessel respectively. 9 figs., 2 tabs.
