Abstract
Drive device for a stopper closure on a metallurgical vessel, including a housing arranged on the vessel in a removable manner, an adjustment system mounted in the housing so as to be height-displaceable and has a drive which can be coupled to the housing, and an upper connection element for a support arm carrying the fire-proof stopper. The adjustment system for the stopper is mounted so as to be height-displaceable on at least one bearing shaft fastened in the housing. This design of the adjustment system permits an increase in the stiffness of the drive device and hence of the fire-proof stopper suspended by the drive device on the support arm during pouring.
