Abstract
A sliding closure for a metallurgical vessel comprises an elongated refractory slide plate (2), which is exchangeably arranged in a metal frame (1) and the longitudinal direction (L) of which corresponds to the direction of displacement of the sliding closure. Also provided are means (3) for bracing the slide plate (2) in the metal frame (1), which comprise a wedge shoe (10) that is loaded by a spring (9) and can be adjusted transversely in relation to the direction of displacement of the sliding closure. This wedge shoe (10) is operatively connected to a counterpart (11), which can be brought into connection with the slide plate (2) and acts on the slide plate (2) in its longitudinal direction (L). The oscillating movements of the movable slide plate taking place during operation are absorbed and the bracing device ensures satisfactory bracing of this slide plate at any time.
Description
The present invention relates to the slip lid that is used for metallurgical tank according to the preamble of claim 1.
In slip lid, be known that it is fire-resistant, at corresponding metal frame or compacted in housing, adjustment screw directly is bonded on the peripheral region of corresponding plate to removable cover plate by means of adjustment screw.At this, especially be in constantly by its driver for being in operation for the movable slide plate in the oscillating motion (Oszillationsbewegung), be faced with such danger, promptly, one or more adjustment screw are unclamped in non-desired mode, and this compress and thus whole service all be adversely affected.
The present invention is based on following task,, provides the slip lid of such type that beginning is carried that is, therein, and being pressed on the affected danger of run duration and can being eliminated as much as possible of plate.
According to the present invention, the slip lid of the feature of this task by having claim 1 is realized.
Constitute the theme of dependent claims according to other favourable design of slip lid of the present invention.
In slip lid according to the present invention, the oscillating motion that produces that is in operation of movable slide plate is cushioned (aufgefangen), and compression apparatus guarantees that constantly the flawless of this slide plate compresses.
Below will be described in more detail the present invention by means of accompanying drawing.Wherein:
Fig. 1 has shown metal frame in plane, this metal frame has therein the slide plate compacted by means of compression apparatus, and this slide plate is as the part according to slip lid of the present invention; And
Fig. 2 has shown the metal frame that has based on the slide plate of Fig. 1, and wherein, compression apparatus is in inoperative position.
Shown the part of the slip lid that can be used at the outlet of metallurgical vessel place in Fig. 1 and Fig. 2, it comprises metal frame 1, and is arranged in fire-resistant, the microscler slide plate 2 in the metal frame 1 replaceably.The slide plate 2 that is provided with through hole 5 is compacted in metal frame 1 by means of compression apparatus 3.Fig. 1 has shown the compression apparatus 3 that is in its position of working, and Fig. 2 has shown the inoperative position of compression apparatus 3, can for example carry out plate and change in this inoperative position.Metal frame 1 also can be the housing parts of slip lid, and in this case, slide plate self is inactive, but equally also bears shuttle power owing to the slide plate of the swing that is adjacent.
Slide plate 2 is movable slide plates of slip lid, by its on its longitudinal direction L with respect to the moving of at least one static slide plate, the outlet of container (for example pouring molten steel bucket or intermediate distributor) can be closed in known manner, throttling or open.The metal frame 1 that holds slide plate 2 can utilize for this purpose its end 4 with same known and thereby the mode and the driver that are not described in detail in this couple.
During wedge shape boots 10 and adjustment screw 26 are in and are threaded, this adjustment screw 26 is directed in the opening 25 at metal frame 1 on transverse to the longitudinal direction L of slide plate 2 loosely, and, this adjustment screw 26 is screwed in the peg (Zapfen) 28, and this peg 28 is inserted in the wedge shape boots 10 and is provided with screwed hole 27.Adjustment screw 26 and peg 28 are arranged to be perpendicular to one another.Adjustment screw 26 has head of screw 29, and when handling this adjustment screw 26 on rotation direction, this head of screw 29 comes on the step surface 30 (Fig. 2) of opening 25.In order to be limited in motion in the manipulation of another rotation direction to adjustment screw, in metal frame 1, insert limited untie-sell 33, this stopper pin 33 engages in the microscler recess 34 in the adjustment screw 26, and with the latter's stop surface 35 actings in conjunction.
Affact that spring 9 on the wedge shape boots 10 is coaxial to be arranged in adjustment screw 26 ground.
If now, according to Fig. 1 in metal frame 1 by means of compression apparatus 3 compacted and by the pairing piece 11 be pressed into supporting surface 40,41,42, slide plate 2 (for example) on 43 need be replaced, then the adjustment screw 29 by handle adjustment screw 26 on rotation direction is positioned on the step surface 30 of opening 25 up to it.At this, in the further rotation of adjustment screw, wedge shape boots 10 are conditioned against the power of spring 9 in recess 20, are compressed (referring to Fig. 2) up to spring 9.This wedge shape boots are regulated and are also caused matching piece 11 by guide surface 30 and be conditioned and deviate from slide plate 2, and this slide plate 2 can be taken out from metal frame 1 now.
In order to compress the slide plate 2 of newly putting into metal frame 1, on another rotation direction, handle adjustment screw 26, wedge shape boots 10 move and match piece 11 again towards slide plate 2 motions on the direction of the power of spring 9 thus.In case the supporting surface 12 of pairing piece 11,13 rest on the circumferential surface of slide plate 2, then slide plate 2 is compacted by the power of spring 9, in this case, in further rotating, head of screw 9 migrations of adjustment screw 26 are away from step surface 30, and the stopper pin 33 that is come on the stop surface 35 until adjustment movement stops.Stopper pin 33 prevents that adjustment screw 26 from fully being back-outed from wedge shape boots or its peg 28.The existence of peg 28 is not the sin qua non.Adjustment screw 26 also can directly be screwed in the wedge shape boots 10.Yet peg 28 has allowed the zero clearance to a certain degree of each part of pre-compression apparatus 3 in an advantageous manner.
In slip lid according to the present invention, can bear the oscillating motion of the movable slide plate 2 of generation in service by spring 9, and compression apparatus 3 can be guaranteed the compressing of no problem of this slide plate constantly.
In current exemplary embodiment, the adjustment angle of wedge shape boots 10 or pairing piece 11 is about 10 °.Should be noted that at this this angle can not select too smallly, block too consumingly thus to avoid self-locking and wedge shape boots.This adjusts the angle preferably between 3 ° and 15 °.
