Arrangement for connecting a stopper-rod for a metallurgical vessel to its lifting device, and stopper-rod suitable for the arrangement, and method for producing the arrangement

摘要

The arrangement (100) has a holding rod (10) which is bisected into an upper part (18) which can be mounted on a lifting device and into a lower part (1) which projects into a stopper-rod (2), said holding rod comprising a fast-acting coupling device for the firm, gas-tight connection of the lower part (1) to the upper part (18), which fast-acting coupling device allows simple exchange of a worn stopper-rod. The region of the lower part (1) of the holding rod (10) projecting into the stopper-rod (2) is provided with engagement means (3, 4, 35) which engage with the ceramic material of the stopper-rod (2) by common, isostatic pressing and produce a gas-tight, non-releasable connection of the lower part (1) of the holding rod (10) to the stopper-rod (2). <IMAGE>
