Abstract
The invention aims at solving the problems of the existing stopper rod nozzle flow control device that when a stopper rod is deviated from the axis of the nozzle, the stopper rod and the nozzle are damaged because the stopper rod cannot be effectively prevented from eccentrically contacting the nozzle. The stopper rod flow control structure comprises a nozzle on the bottom wall of a tundish and a stopper rod matched with the nozzle, wherein a plurality of fixed blocks are also arranged on the bottom wall of the tundish, the fixed blocks are arranged on the periphery of the nozzle and are circumferentially distributed along the axis of the nozzle, the upper end surface of each fixed block is arranged above the upper end surface of the nozzle, guide blocks matched with the fixed blocks are fixedly arranged nearby the position above a choke plug of the stopper rod, and a reinforcing rib is arranged between the upper end surface of each guide block and the outer circumferential surface of the stopper rod; a columnar guide groove is formed in one surface, adjacent to the axis of the nozzle, of each fixed block, the axis of the guide groove is parallel to that of the nozzle, and the guide blocks are arranged in the guide groove in a matching manner. The stopper rod flow control structure has the beneficial effects that the problem that the stopper rod is broken or damages the nozzle due to the eccentric contact between the stopper rod and the nozzle can be prevented.
Description
Technical field
The present invention relates to middle water containing opening flow control technique field, more particularly to a kind of stopper and mouth of a river secure fit
Stopper rod flow control structure.
Background technology
Stopper-mouth of a river flow control structure is a kind of conventional flow control structure in basket pouring control, and this structure includes setting
Put the nozzle brick with the mouth of a river on tundish bottom surface and coordinate the stopper on the mouth of a river.By controlling the relative mouth of a river of stopper
Position is controlling the aperture at the mouth of a river, and then controls poring rate.Under normal circumstances, the axis of the axis at the mouth of a river and stopper should be
On same straight line, at this moment the arbitrary cross section of stopper and the cross section at the mouth of a river are concentric, and stopper comes downwards to the inwall at the contact mouth of a river
When, just can completely enclose the mouth of a river.Alignment error yet with stopper handle structure or in use stopper position
The deviation of appearance, may all cause the axis at the original mouth of a river of axis runout of stopper, at this moment the horizontal stroke at the cross section of stopper and the mouth of a river
Just there is bias in section, and such side-play amount is often smaller, it is difficult to be visually detectable；So stopper comes downwards to the contact mouth of a river
During inwall, will be unable to close the mouth of a river completely, if stopper is continued traveling downwardly behind the contact mouth of a river, can make increase by stopper curved again
Square load, easily causes fractureing for stopper, while stopper also becomes big with the pressure that the contact site at the mouth of a river is subject to, can cause stopper
Or the contact fatigue failure on mouth of a river surface.
For example, in existing open file, there are 201895085 U of Publication No. CN, publication date for 2011.07.13's
Chinese patent literature, discloses a kind of two-seater brick nozzle brick of utilization stopper rod flow control, including upper brick cup and lower brick cup, upper brick cup and
Lower brick cup inlays fixed Combination by rim of the mouth and female mouth；The upper brick cup includes brick body, steel-connecting port, steel runner；The lower brick cup
Including brick body, steel runner, wherein the stopper of and steel-connecting port mating shapes is provided with the steel-connecting port of upper brick cup.The invention
It is disadvantageous in that, stopper is with the mouth of a river without aligning structure, it may appear that during stopper axis runout nozzle axis, affects the envelope at the mouth of a river
Close or cause stopper bending moment fracture, and the mouth of a river contact force increase produce contact fatigue failure.
The content of the invention
To solve existing stopper mouth of a river flow control device when stopper deviates nozzle axis, it is impossible to effectively prevent stopper and water
Mouth bias is contacted and the problem at infringement stopper and the mouth of a river, and present invention offer one kind is prevented from contact eccentric with the mouth of a river of stopper and causes
Stopper fractures or damages the stopper at the mouth of a river and the stopper rod flow control structure of mouth of a river secure fit.
To achieve these goals, the technical solution used in the present invention is：
A kind of stopper rod flow control structure of stopper and mouth of a river secure fit, including the mouth of a river being arranged on tundish diapire and with
The stopper that the mouth of a river is engaged, is additionally provided with some fixed blocks on tundish diapire, fixed block is arranged on the periphery at the mouth of a river, and around water
The axis of mouth is circumferentially distributed, and the upper surface of fixed block is nearby fixed with above the plug of stopper on the upper surface of the mouth of a river
The guide block being engaged with fixed block, is provided with reinforcement between guide block upper surface and the outer circumference surface of stopper.When stopper is descending, it is necessary to
Guide block thereon is made first by the fixed block that is coaxially disposed with the mouth of a river, when stopper deviates the axis at the mouth of a river, the guide block on stopper
To be blocked on the upper surface of fixed block, it is impossible to further contact the mouth of a river, it is therefore prevented that harmful load that both eccentric contacts are caused
Lotus, so as to play a protective role to stopper and the mouth of a river, it is to avoid both damage；It is strong with the connection of stopper that reinforcement increases guide block
Degree, can prevent guide block from being collided fracture failure.
Preferably, fixed block is provided with the guide groove of cylindricality, axis and the mouth of a river of guide groove near the one side of nozzle axis
Diameter parallel, guide block coordinate in guide groove.The setting of guide groove causes position skew of this structure to stopper more sensitive.
Preferably, the cross section of guide groove is semicircle, accordingly, at guide block and guide groove cooperation, the outside of cross section is also
It is semicircle.Than square-section, position skew of the semicircular cooperation section to both is more sensitive, so can ensure that and is leading
When block can pass through guide groove, the dead in line at stopper and the mouth of a river, both being capable of normally closed.
Preferably, the quantity of fixed block is four, and the axis around the mouth of a river is uniformly distributed.Equally distributed fixed block
Make this structure stress in order.
Preferably, the refractory protection of a floor height hardness is equipped with the upper surface of the lower surface of guide block and fixed block
Layer, refractory protection thickness are 5mm to 10mm.Due to when stopper deviates mouth of a river center, the lower surface of guide block and fixed block
Upper surface more collision or contact occurs, the refractory protection of high rigidity can increase both effective time, it is to avoid
Both too early deformation failures.
The invention has the beneficial effects as follows：Can be limited by being oriented in advance, prevent stopper from contacting with mouth of a river bias and cause plug
Rod fractures or damages the mouth of a river.
