An improved apparatus (100) and an improved method (110) using the improved apparatus for removing a quantity of slag (24) from hot metal (6) in a ladle (2) during a process of metal purification such as steelmaking. The improved apparatus is an improved skimmer paddle having a system of internal piping (60) that at one end is attached to a source of gas and at a second end terminates into one or more ports (64). The improved skimmer (100) is moved along a top surface (6a) of the hot metal, though the quantity of slag, and predetermined flows of gas are forced into the piping system and expelled through the port or ports (64) to move the quantity of slag out from the back of ladle to be skimmed into a slag pot (4) to remove undesired impurities from the hot metal. |
