A metal casting installation is provided that includes a loading platform, a tundish, a first ladle and a second ladle, each of the first and second ladle has a floor provided with an opening, a collector nozzle and a ladle shroud. The installation also includes a ladle sliding gate configured for moving the collector nozzle and the ladle shroud between a sealed position, a casting position, and an unclogging position. A turret is provided for holding the first and second ladles, configured for moving and holding in place the first and second ladles between a loading station and a casting station over the tundish. A robot is also provided and configured for loading a new ladle shroud onto the ladle slide gate, and coupling a driving device to the ladle slide gate.

A coupling position switching mechanism capable of improving efficiency of a coupling position switching operation, while realizing structural simplification, and reductions in size and cost. A first coupling portion consisting of one of a slide metal frame-side coupling portion and a drive unit-side coupling portion is formed with a groove-shaped recess and a through-hole in this order from the side of a distal end of the first coupling portion, and a second coupling portion consisting of the remaining one of the slide metal frame-side coupling portion and the drive unit-side coupling portion is formed with the through-hole. The first and second coupling portions are configured such that, during a casting operation, they are coupled together by a coupling pin inserted into the through-hole of the first coupling portion and the through-hole of the second coupling portion, and during surface pressure-applying/releasing operation, they are coupled together by a second coupling pin inserted into the groove-shaped recess of the first coupling portion and the through-hole of the second coupling portion.

A control method and apparatus for inhibiting slag entrapment in ladle (1) during continuous casting production. An optimal control model calculating unit (11) receives related signals and data sent by a ladle weight detector (4), a molten steel flow field detector (5), a slag detector (7), a sliding gate opening detector (9), and a process signal interface unit (10), performs calculation and analysis according to an optimal control model to obtain a corresponding optimal control strategy, and outputs the strategy to an electromagnetic brake (6) and a sliding gate controller (8) for slag entrapment inhibition control. Regarding the two processes where a vortex may be formed, by means of different optimal control strategies, which respectively inhibit or destroy the formation of a vortex, slag generation is postponed, and molten steel may flow out without bringing slag out, thereby reducing residual ladle steel and improving molten steel yield.

A vibratory system and method for use in transferring molten metal. The vibratory system includes a vibrator which generates vibrational energy used to dislodge particulate positioned in a ladle for storing molten metal in an industrial molten metal transfer and manufacturing process. In one example, the vibratory system includes a transfer device for guiding the molten metal from the ladle and the vibrator is connected to the transfer device. In an example of a method for dislodging the particulate from the ladle, particulate is added to the ladle and vibrational energy is applied or transferred to the ladle to dislodge the particulate from the ladle allowing a flow of the molten metal to exit the ladle unobstructed by the particulate.

A control method and apparatus for continuous casting steel pouring are provided, wherein the amount of the molten steel flow of the ladle is controlled, thereby improving the yield of the molten steel and decreasing the production cost.

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.
