摘要： A rotary nozzle which is simple in construction and easy to manufacture its bricks, has no danger of leakage of molten steel and is capable of rotatably connecting a collector nozzle and a long nozzle. The rotary nozzle includes a fixed plate brick attached to a base member and having at least a sliding surface thereof formed to incline with an angle of .theta..degree., a slide plate surface having at least a sliding surface thereof formed as an inclined surface corresponding to the sliding surface of the fixed plate brick and fixedly mounted, along with a collector nozzle, in a supporting member, and a frame vertically displaceably supporting the supporting member through a plurality of spring means and bolts and adapted to be driven by driving means mounted on the base member. The lower end of the collector nozzle is formed into a spherical shape so as to ensure its smooth connection with a long nozzle and its rotation.

摘要： A non-reversible plate having a depending tube structure with a discharge opening at the bottom in which there is a plate at the upper portion, rectangular in configuration, and which has an irregular anti-reversal collar beneath the plate portion is disclosed. Desirably the collar is elliptical in configuration and has a major axis at least seven millimeters longer than the minor axis. The longer axis is parallel with the length dimension. Another aspect of the invention is the utilization of a toggle actuated plate changing device which swings in and out of position and can only be actuated when the plate and tube intended for insertion presents the length for insertion into the valve structure. Suitable microswitch or related device is provided to permit actuation of the change actuator, but only when the plate is properly oriented for insertion. The method of the present invention includes the steps of pre-orienting and proportioning a tube or shroud having a plate at the upper portion for insertion into a plate changer assembly.

摘要： A sliding gate valve for metallurgical vessels, such as pouring ladles, is disclosed. The sliding gate valve may include a slide gate housing fastenable to a melt-containing vessel. A heat-resistant closure plate may be held stationary by a movable slide plate pressing against the closure plate. The slide plate may be supported in a frame having two sets of rollers. The frame may be connected to a drive, for example a hydraulic or pneumatic drive. An aperture may be provided in the housing bottom for passage of the frame rollers therethrough. The distance corresponding to the axial spacing between the sets of rollers is equivalent to the distance corresponding to the axial spacing between side apertures of the bottom aperture. The axial spacing between the rollers corresponds to the axial spacing between the side apertures to allow for the simultaneous passage of both sets of rollers through the side apertures. The frame may be guided in the housing on a slide comprising side aperture closing portions which may be displaced to open and close the side apertures of the housing bottom. The frame and the slide may be provided with bores that may be temporarily and rigidly connected with each other by a connecting bolt. Each roller of one set of rollers may be equipped with a releasable connecting bolt cooperating with a housing receptacle.
摘要翻译： 公开了一种用于冶金容器的滑动闸阀，例如倾倒浇包。 滑动闸阀可以包括可固定到熔化容器的滑动门壳体。 耐热封闭板可以通过压靠封闭板的可动滑板来固定。 滑板可以支撑在具有两组辊的框架中。 框架可以连接到驱动器，例如液压或气动驱动器。 可以在壳体底部中设置孔，用于框架辊通过其中。 与辊组之间的轴向间隔相对应的距离等于与底孔的侧孔之间的轴向间隔相对应的距离。 辊之间的轴向间隔对应于侧孔之间的轴向间隔，以允许两组辊同时通过侧孔。 框架可以在壳体中被引导到包括侧孔闭合部分的滑块上，该侧孔可以被移位以打开和关闭壳体底部的侧孔。 框架和滑动件可以设置有可以通过连接螺栓彼此临时且刚性地连接的孔。 一组辊的每个辊子可以配备有与壳体容器配合的可释放的连接螺栓。

摘要： A linear sliding closure unit includes a stationary refractory plate, a closure casing adapted to be mounted on a molten metal container, a linearly movable sliding refractory plate, a sliding closure member mounting the sliding refractory plate for linear sliding movement relative to the casing and the stationary refractory plate, and structure for urging the sliding refractory plate toward the stationary refractory plate so that respective sliding surfaces thereof are in abutment. The closure casing includes an inner supporting surface supporting and defining the position of the stationary refractory plate. The closure casing has guide surfaces at positions outwardly of the support surface, the sliding closure member being guided by the guide surfaces during sliding movement. The closure casing fixedly connects and spaces the guide surfaces from the supporting surface.

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： 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： Sliding closure for a receptacle containing molten metal includes a housing frame that can be fastened to a spout of the receptacle, a first refractory base plate and a sliding unit having a refractory sliding plate that is sealingly pressed against the first base plate by spring elements and a contiguous refractory spout sleeve contained in the housing frame. The case has a second base plate juxtaposed to the first base plate and displaceable inside the housing frame at a right angle to the direction of movement of the sliding unit from an initial position in which the first base plate is in an operating position towards a final position in which the second base plate is in the operating position. It is therefore possible to replace the base plate, which wears outs quickly, by a new base plate in a rapid and convenient manner without interrupting the casting operation.

摘要： 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.
