  • Patent number: 11331719
    Abstract: Slide gate for a metallurgical vessel, in particular a ladle, including a slide gate housing attachable to a metallurgical vessel, a head plate accommodated in the slide gate housing and having a passage opening for a metallic melt, a slide frame mounted in the slide gate housing so as to be displaceable in a direction relative to the head plate, and a slide plate accommodated in the slide frame and having a passage opening, characterized in that a device for compensating the contact pressure of the slide plate against the head plate is arranged between the slide gate housing and the slide frame, wherein the compensating device includes at least one carrier body mounted in the slide gate housing so as to be rotatable about at least one axis of rotation, and at least one spring element, via which the carrier body is coupled to the slide frame.

  • Patent number: 5118084
    Abstract: An apparatus for controlled adjustment of a stopper of a distributor channel or metallurgical vessel in a continuous casting plant (for billets or ingots), the stopper being connected to a crosstie or stopper rod disposed above the distributor channel or metallurgical vessel, and the crosstie or stopper rod itself being connected to a support bar which is movable up and down in a vertical guide means. The vertical guide means of the support bar is a roller guide means comprising support rollers or support balls which are clamped without clearance between the support bar and an outer housing.

  • Patent number: 5110018
    Abstract: A closing apparatus for the bottom pouring hole of a casting ladle, comprising a mounting plate mounted on the bottom of the ladle with a head plate resting against it, in which head plate a port is formed to pour out the melt, and further comprising a slide plate supported for pivoting movement about two axes and adapted to be pressed resiliently against the head plate. The slide plate is supported for reciprocating movement inside a housing. The housing is supported by a housing carrier structure, especially between the legs of carrier bracket for the housing, for pivoting movement about a first pivot axis, while the carrier bracket for the housing is supported by the mounting plate for pivoting about a second pivot axis. The first and second pivot axes extend parallel to each other and to the sealing face between the head and slide plates.
