  • Device for unclogging a lance intended to be inserted into a metallurgical vessel
    Patent number: 5152952
    Abstract: This device comprises a fixed support constituted by a cylindrical collar 14, through which the lance 5 may be axially displaced and scraping fingers 16 whose extremities, which comprise cleaving means 21, may be held substantially in contact with the lance. A clearance is arranged, between the lance and the collar, which is sufficient to allow the accretions 12 of materials which it is desired to remove from the lance to pass through. While the lance is being raised, the extremities of the fingers cleave the accretions until they are totally broken off from the lance and can then fall into the vessel.The device is particularly applicable to the unclogging of oxygen lances used in steelworks converters.
