Abstract (en)

[origin: WO03018231A1] A method and apparatus for stirring and treating continuous and semi-continuous casting of metallic rods (12). The apparatus comprising: a stand (30) for suspending at least one electric arc electrode (24) over the upper surface of a metallic casting (14) after or during pouring, at least one electrode (24) for forming a moving electric arc (38) over the upper surface of the mettalic casting being cast, a second electrode, being the liquid metal (14), for completion of an electric circuit including said electric arc (38) and the liquid metal (14); and control means (34), connected between said apparatus and a power supply (36) and arranged to supply power to the plasma arc electrodes (14, 24), for monitoring the parameters of the electric arc (38). The invention also provides a method for casting the metallic rods (12) by using the above described apparatus.
