る。When removing metal, etc., operate the electric chain hoist 15 to lower the scraper tip 11 to a position where the metal can be scraped off. When the metal and slag adhering to the upper edge of the hot metal pot hit the scraper rod, a scratch groove is formed in the adhering layer of the metal and slag, and the metal is removed. The adhesion layer of the base metal and the slag is then scraped off by the scraper tip 11. When the adhesion of the base metal and the slag is strong, the mounting frame 10 is moved in the direction of movement of the pot. It is pressed by A> in Figure 2, but it is located at the rear.
The base metal and slag are scraped off while being supported by a vessel 19. When the adhesion of the base metal and slag is even stronger, use JJ! ffl device 1
9 contracts, allowing the mounting frame 10 to escape. Since the shock absorber 19 is also provided in the direction opposite to the traveling direction A (B) in Fig. 2, in such a case, move the hot metal ladle 1 in the directions A and B. It can be moved back and forth to scrape off adhered metal and slag.
