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： 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 supported to move 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 by mounting the joining block tool therebetween, and a joining-released state where the support bar member and the case do not cooperate with each other by dismounting the joining block tool, and a spring member generating a force applying a contact pressure according to a position of the support bar member.

摘要： 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.

摘要： Metal flow from furnace taphole to a pouring trough is controlled by a valve interposed therebetween, the valve having a stationary orificed valve plate and a companion slide plate for closing or opening the orifice to flow. An actuating beam member forming part of a parallel motion linkage extends upwardly and obliquely from the slide plate, the actuating member being thrust against the slide plate by a swinging spring strut of the linkage. A ram connected to the linkage via a crank, a shaft and a pivoted lever displaces the linkage when extended or contracted and this moves the actuating member along a predetermined path, its oblique attitude being preserved, to open or shut the valve.
