Abstract (en)
[origin: US4402437A] A protection arrangement for a casting jet emerging from a metallurgical vessel includes a protective tube enveloping the casting jet and fastened to an articulation-rod assembly that is pivotable into any space direction. In order to be able to follow any desired position of the casting jet with the protective tube, the articulation-rod assembly includes a first, vertically extending, four-bar linkage parallelogram which is mounted with its vertically arranged web so as to be rotatable about a vertical axis. To its coupler, an extension arm carrying the protective tube is hinged, forming the oscillating crank of a second four-bar linkage. The web of the second four-bar linkage is formed by an oscillating crank of the first four-bar linkage parallelogram.
