ABSTRACT:
A hydraulic cylinder 41 of a second driver 40 brings both a scraper 20 and a first driver 30 into integrally movable relation so that the scraper 20 is caused to intrude into an uptake 10 of a furnace via an opening 14 defined on a vertical wall of the uptake 10, and an accretion removing pawl 21 is positioned on a horizontal wall surface 12 of the uptake 10. Subsequently, a hydraulic cylinder 31 of the first driver 30 moves the scraper 20 on the horizontal wall surface 12 to scrape off any accretion having occurred thereon. The accretion thus scraped is blown off the horizontal wall surface 12 by pressurized air supplied from a pressurized air-supplying source connected to a flange 27.
