摘要： The invention is directed to a method of and apparatus for, introducing into a bath of molten metal (e.g. ferrous metal) contained in a vessel an alloying component (e.g. lead) or a reagent. The method includes the steps of connecting a plurality of plugs or nozzles located in the bottom and/or sides of the vessel to supplies of gas (e.g. argon) under pressure, and causing gas to be introduced simultaneously through the plugs or nozzles to produce individual gas flows which pass upwardly through the metal bath to create areas of turbulence on the bath surface. The areas of turbulence interact to produce on the bath surface a relatively quiescent region and it is into this relatively quiescent region that the required quantity of alloying component or reagent is added.

摘要： This invention relates to a water-cooled arc furnace electrode comprising a double-walled tubular metal column the two walls being electrically insulated from one another and defining an annular channel between them. The inner wall is electrically connected to a conductive screw-threaded member from which graphite sections depend, and this inner tube defines a central channel constituting a water flow path connected in series with the annular channel via a "spider" in the aforesaid member. In accordance with this design the volume of water contained within the electrode column approaches the maximum, ensuring adequate cooling during electrode changes which hitherto has presented problems in other designs of this component.
