Abstract
A tensioning device for a sliding gate on the nozzle of a metallurgical vessel includes for the spring mounting of the tensioning device between a gate housing and a housing cover by means of clamping units that connect such two members and that are hinged, to the housing and cross under housing cover 30 bending springs as hinging shafts for clamping units. This results in a simple construction of the tensioning device due to the two modes of operation of the bending springs.
