Abstract: The invention is directed to a plasma torch which projects into a container and is fastened at a supporting device and has a nozzle arranged at a burner lance, as well as a main electrode pipe with a main electrode arranged inside the burner lance, gaseous and liquid media as well as electric current being supplied to the main electrode via coaxially arranged pipes. An annular insulating member (21) is provided around the main electrode (10) in the region of its foot end and encloses the electrode (10) annularly, the casing (33) of the double-walled burner lance (30) which is held by the supporting device being fastened at this insulating member.

Abstract: A continuous casting and rolling device of the type in which molten metal is introduced, by a nozzle, between a pair of liquid cooled rolls which are supported in a roll supporting structure and which each have a coolant connection and a drive which are disposed on different sides or ends of the roll supporting structure. Each roll is equipped with its own geared motor which is releasably fastened to the respective roll pin as a freely projecting drive unit.
