Abstract
A method of removing encrustations from a metallurgical lance comprising the steps of relatively displacing the lance and a tool with the tool in contact with a layer of encrustation on the lance and applying a repetitive movement to the tool against the layer to dislodge the layer from the lance and permit the layer to fall therefrom by its weight.
Claims22
A method of removing encrustations from a metallurgical lance comprising the steps of:
- relatively displacing the lance and a tool with the tool in contact with a layer of encrustation on said lance;
- and
- applying a repetitive movement to said tool against said layer to dislodge said layer from said lance and permit said layer to fall therefrom by its weight.
A device for the removal of a layer of crust on a metallurgical lance suspended and vertically movable by a suspension which comprises:
- a support, said lance being displaceable past said support, a tool mounted on said support and engageable with said layer on said lance, and means for imparting a repetitive movement to said tool in excess of the rate of displacement of said lance.
