The invention discloses a metallurgical furnace
oxygen lance
slag scraper with rotary scraping and impacting, structurally comprising: a
slag scraping device, a power supply frame, a support and a transmission shaft. The metallurgical furnace
oxygen lance
slag scraper with rotary scraping and impacting has the advantages that a power supply mechanism and a scraping structure can cooperate with each other such that triangular
conical teeth on the surface of a threaded bar provide spiral rotational scraping for slag on the surface of an
oxygen lance under the rotational action of the scraping structure so that the slag is cracked; gas leakage due to the oxygen lance breakage caused by surface scratches of the oxygen lance under the action of a traditional slag scraper is avoided; a circularframe rotates synchronously with a scraping
barrel, a vibrating plate is ejected out under the action of an ejector rod, the slag that is cracked is impacted, the cracks are extended to break the slagunder the action of external force, the slag on the surface of the oxygen lance is broken to fall under the
impact action, and it is avoided that gas leakage is caused by
cracking and scratches of the surface of the oxygen lance due to the action of the traditional slag scraper.
