Abstract

A slide closure for a vessel containing molten metal has a slider housing (12), a slide unit guided longitudinally therein, with a slide rod (13), a holder (15) on the slider housing (12) as well as a linear actuator (20) which can be fastened in this holder (15) with a drive rod (20′) which can be coupled to the slide rod (13). The linear actuator (20) can be slid into the holder (15) on the slider housing (12), preferably transverse to its direction of adjustment, and can be removed from same and can be locked in the holder (15). At least one locking means (25, 30) is fastened to each of the linear actuator (20) and the holder (15), which locking means are developed to interact such that the linear actuator (20) locks automatically after or during being pushed into the holder (15). A permanently secure fastening of the linear actuator in the holder thus results.

Abstract

A method is provided, in particular for maintaining a slide gate (10) of a vessel containing metal melts. The slide gate (10) comprises a housing (11), a slide unit guided longitudinally in this, a holding element (15), a linear drive (12) which can be located in this for adjusting the slide unit, at least one electrical line and/or a connection line (16, 17, 18) for a medium, such as gas or air. The connecting of the at least one electrical line and/or the connection line (16, 17, 18) for the medium takes place in this situation by means of a plugging action. This plugging action of the at least one connection line (16, 17, 18) takes place automatically with the moving of the linear drive (12) into the holding element (15), and/or the detachment takes place automatically when it is moved out of the holding element (15). As a result, handling is more easily achieved in particular at the maintaining of the slide gate by means of a robot, and, at the same time, the process stability and the operational safety are increased during the casting.

Abstract

A sliding closure (1) for a metallurgical vessel is provided with a slider unit (7), a refractory closing plate (3) which can be inserted therein, a refractory exchangeable spout (4) which can be sealingly connected to the closing plate (3) and has a top face (15) and an outlet opening (24), and a fastening means (8). By means of said fastening means (8), the exchangeable spout (4) can be pressed against a stop (9) in the slider unit (7). Said stop (9) in the slider unit (7) and the exchangeable spout (4) are each designed with a stop surface (16, 17) conically tapering toward the closing plate (3) such that, when assembled, they are correspondingly pressed against one another with a refractory sealing material between the exchangeable spout (4) and the slider unit (7). Improved axial and lateral fixation between these components is therefore achieved, thereby reducing the risk of breaching.

Abstract

Method, imaging system (5), data processing device (60) and system (10) for determination of a 3D information (90), especially of a point cloud (80) or of a 3D surface reconstruction (81) or of a 3D object (82), of an inner part (55) of a metallurgical vessel (50) or of a modification, the method comprising the steps of providing (100) a metallurgical vessel (50); capturing (110) a first optical image (21) of at least one first inner part (51) of the metallurgical vessel (50), from a first imaging device position (22) outside of the metallurgical vessel (50), with a first optical axis (23), by a first imaging device (20); capturing (120) a second optical image (31) of at least one second inner part (52) of the metallurgical vessel (50), from a second imaging device position (32) outside of the metallurgical vessel (50), with a second optical axis (33), by a second imaging device (30); calculating (130) a 3D information (90), such as a point cloud (80) or a 3D surface reconstruction (81) or a 3D object (82), of at least one inner part (55) of the metallurgical vessel (50) from at least the first optical image (21) and the second optical image (31), whereas the first optical image (21) is captured from a first fixed imaging device position (22) with a first fixed optical axis (23) and whereas the second optical image (31) is captured from a second fixed imaging device position (32) with a second fixed optical axis (33).

Abstract

The invention relates to a sliding closure (10) for a metallurgical vessel comprising a tapping hole (1) for draining metal melt or slag, said sliding closure being provided with a slider housing (3) that can be secured to the vessel (2) and a closure plate (6) that can move therein for opening and closing the tapping hole (1). The sliding closure (10) also has only this moveable closure plate (6), without a stationary closure plate, which is can be moved directly on a sliding surface (7), extending around the tapping hole, preferably of a casing block (9) in the vessel (2) and can be pressed by pretensioning elements. In this way, this sliding closure (10) provides a constructionally simpler structure and user-friendly handling.
