摘要： 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.

摘要： 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.-

摘要： A sliding gate device includes a fixed plate fixed to a molten steel container, a sliding plate for opening/closing a nozzle hole, a sliding device moving a case holding the sliding plate, and a contact pressure control mechanism switching between a contact pressure applied state and a no-contact-pressure applied state for the fixed plate and the sliding plate. The contact pressure control mechanism has a support bar member moving relative to the fixed plate, a joining block tool switching between a joined state where the support bar member and the case cooperate with each other, and a joining-released state where the support bar member and the case do not cooperate with each other, and a spring member generating a force applying a contact pressure according to a position of the support bar member.

摘要： In a sliding gate, a flow path vertical angle a between a flow path axial direction and a vertical downstream direction in a flow path hole in each plate is 5° or more and 75° or less, and a flow path axial direction projected on sliding surface in which the flow path axial direction is projected on a sliding surface differs between the plates and is changed clockwise or counterclockwise toward a downstream side. Then, molten metal forms a turning flow in the flow path hole of the sliding gate. Furthermore, the molten metal also forms a turning flow in a ladle shroud on the downstream side of the sliding gate.

摘要： A sliding gate valve of a metallurgic vessel comprises a carriage. The carriage comprises a plate frame for supporting a first refractory plate and the plate frame is slideably mounted on a carriage support structure for sliding along a first axis. The carriage comprises a selecting device for selecting between a first stroke ΔX1 and a second stroke ΔX2 by moving a blocking member between a blocking and a non-blocking position. When the blocking member is located in the blocking position a first bumper portion of the plate frame is bumping into the blocking member if the plate frame is to slide beyond a nominal end-position. When the blocking member is located in the non-blocking position the first bumper portion is not bumping into the blocking member if the plate frame is to slide beyond a nominal end-position, thereby allowing the plate frame to slide beyond the nominal end-position to a service end-position.

摘要： With a method for detecting variables in an outlet of a metallurgical vessel, different variables in the outlet are detected or measured by at least one coil surrounding the outlet channel and/or an induction coil of an induction heater as a monitoring system, wherein the variables relate to the slag portion when pouring out the metal melt, wear condition of refractory parts in the outlet channel, the solidified metal melt, flow rate and/or plugging mass in the outlet channel. After evaluation, a closure element for the outlet is actuated, heating of the metal in the outlet channel is activated and/or renewal of the outlet channel is triggered. In this way, optimum operation in the pouring of metal melt out of a vessel is simply achieved, wherein occurrence of irregularities are detected during the entire pouring, and pouring out of slag can be successfully prevented at the end of the pouring.

摘要： Slide closure for a metallurgical vessel, with two compensation units I and II for equalizing overloads, which may result from the thermal extension and spreading of the fire-proof closure plate thicknesses conditional on manufacturing, and/or from the upper inner shell, wherein the inner shell can also be reduced during operation. The compensation unit I consists of a spring arrangement with fastening screws which can be moved away between the housing and a cover of the housing. The compensation unit II consists, for its part, of a spring arrangement with an insertion frame pressing against the lower closure plate, which insertion frame is fixed to the bottom of the housing with fastening screws.

摘要： The apparatus for continuous slab casting having a nozzle exchanging-holding mechanism capable of moving a submerged nozzle at the exchange of the nozzle through a moving-connecting space D of a base under a slide valve mechanism and keeping the connection between the submerged nozzle and the slide valve mechanism during the operation, and a rotation mechanism to rotate the base of the nozzle exchanging-holding mechanism, which is characterized by a fixing mechanism that fixes the submerged nozzle in the nozzle exchanging-holding mechanism by pressing the submerged nozzle toward one or both inner sides of the moving-connecting space D of the base in one or both directions perpendicular to the moving direction of the submerged nozzle during the nozzle exchange.
