In order to be able to carry out a multiplicity of continuosly recurring activities at a continuous casting plant having at least one multifunction robot for implementing a plurality of different process-controlled or automated interventions at the continuous casting plant, at least one working region at the continuous casting plant and at least one multifunction robot assigned to each working region. The multifunction robot is arranged on a pivotable arm at a rotary column fastened to the pouring platform of the continuous casting plant and the robot can be pivoted with the pivot arm between a retraction position and a working position. The robot is also movable with respect to its arm.

A roll (1) for supporting and conveying hot material, including a roll element that has a roll jacket (2) made of a basic material and a wear coat which is applied to the basic material by means of a surface welding process (4) using a welding additive which surrounds the surface of the roll jacket. In order to increase the service life of the wear coat, improve the resistance to wear, and reduce the cost for producing the welded-on surface. The basic material of the roll jacket (2) is steel and contains up to 0.45 percent of C. The welded-on surface (4) is designed as a single-layer weld, and the wear coat contains 12.5 to 14.0 percent of Cr at least in an external zone that surrounds the surface of the roll jacket. Also disclosed are a method for producing the roll (1), a method for repairing a used roll (1), a welding additive and a welding rod for producing the welded-on surface.

A device for interchangeable connection of a casting tube to a spout of a melt vessel with a sliding closure fastened on a melt vessel. The closure is formed by at least one stationary closure plate and a closure plate that can be displaced relative thereto, wherein the displaceable closure plate is coupled to a sliding drive system and carries the casting tube. To improve the changeover process of a casting tube and to make it safer, the displaceable closure plate carries a connecting ring for the centered accommodation of the casting tube and the displaceable closure plate carries a changing device for the casting tube. The changing device is synchronously displaceable with the displaceable plate. A tensioning device presses the casting tube onto the displaceable closure plate.

A continuous casting installation is equipped with at least one robot for carrying out process-controlled or automated interventions on the continuous casting installation and accessing the assigned auxiliary devices. To ensure optimum use of the robot(s), the continuous casting installation is assigned a runway, the robot is assigned a travelling mechanism and the travelling mechanism is displaceably guided on the runway, at least one parking position and at least two operating positions are defined for the robot on the runway and each operating position is assigned working areas on the continuous casting installation that can only be reached from this operating position, the distance between each operating position of the robot and the assigned operating area or supply area is fixed within the minimum and maximum range of the robot arm and the robot is equipped with a data transmitting and receiving device and the latter is connected by signalling technology to a central control device or a process computer of the continuous casting installation. Furthermore, the invention comprises a method for operating a continuous casting installation including at least one robot which can be displaced on a runway between a parking position and at least two operating positions.

A continuous casting mold having side walls through which a coolant flows includes a hydraulically operated oscillation device and a guiding device supporting the continuous casting mold relative to a stationary supporting structure. In order to do with a structurally very simple oscillation device having slight masses to be moved and to markedly reduce the space required by the oscillation device in the vicinity of the continuous casting mold, the oscillation device includes a pulsator setting the coolant into a pulsating pressure course and a supporting device is provided between the continuous casting mold and the stationary supporting structure, resiliently acting in accordance with the pulsating pressure course of the coolant and absorbing oscillation forces.
