Description
Technical field
The present invention relates to middle water containing opening technical field, particularly relate to a kind of tundish slide gate nozzle flow control structure.
Background technology
Steel ladle sliding water gap is the important system controlling molten steel flow in ladle, and its operation principle makes upper slide and lower skateboard generation relative sliding by slide mechanism, makes the steel outlet hole on it that dislocation occur and regulates the opening and closing of steel stream and the size of flow.
Contact surface between upper slide and lower skateboard namely will as press seal face to ensure the tight not bleed-out of combination between the two, again as rubbing surface to realize relative sliding between the two, therefore need between upper slide and lower skateboard to keep enough thrust to guarantee both bonding tightness, but excessive thrust can cause again frictional force between the two to increase, speed wearing and tearing, and then generation gap, the generation of bleed-out can be caused.
Such as, in existing open file, notification number is had to be CN202447655U, the day for announcing is the Chinese patent literature of 2012-09-26, disclose a kind of bolt presses to exert pressure ladle sliding water gap mechanism, comprise filling pipe end, the lower mouth of a river, installing plate part, base member, frame member, toggle pull bar pressing section, slider bar part and hydraulic-driven part, whole mechanism is arranged on ladle by installing plate by described base member, described frame member is by the toggle tie component of both sides, hold-down bolt is arranged on base member, doorframe track and slider bar track is provided with in described frame member, slider bar parts are arranged on slider bar track, described hydraulic-driven part is connected on slider bar parts by shackle rod, the described lower mouth of a river by screw cover and top-fastener be arranged in frame member.The compacted form of this invention is that hold-down bolt is directly exerted pressure to flexible member.The weak point of this technical scheme is, namely the contact surface that the program exists between upper slide and lower skateboard equally as press seal face again as the situation of rubbing surface, will easily cause the generation of bleed-out.
Summary of the invention
For the upper lower skateboard solving existing slide gate nozzle is difficult to meet the little requirement that combines closely and wear and tear simultaneously, easily there is the problem of bleed-out, the invention provides a kind of gate structure good airproof performance, little, not easily bleed-out, mouth of a river long service life tundish slide gate nozzle flow control structure of wearing and tearing.
To achieve these goals, the technical solution used in the present invention is:
A kind of tundish slide gate nozzle flow control structure, comprise the brick cup be arranged on tundish diapire, upper nozzle brick and the upper slide be connected in turn below upper nozzle brick, lower skateboard, lower nozzle brick, upper nozzle brick, upper slide, lower skateboard, lower nozzle brick has vertical through hole, described each through hole is corresponding composition steel flow port up and down, upper slide and lower skateboard sealing pressing are combined, the lower surface of upper slide and the upper surface of lower skateboard all has groove, groove on upper slide and lower skateboard is combined formation sliding cavity, being provided with in sliding cavity can the movable slider of horizontal slip in sliding cavity, movable slider is provided with and runs through on it, the intercommunicating pore of lower surface, intercommunicating pore is communicated with epimere and the hypomere of steel flow port, the side of upper slide is also provided with handle hole, handle hole runs through the sidewall of upper slide and is communicated in sliding cavity, movable slider is connected with pull bar, one end of pull bar is stretched out from handle hole, sealing ring is provided with between handle hole and pull bar, handle hole one end on upper slide is provided with sealing transparent cover, pull bar stretches out from sealing transparent cover.On pull bar, cover has spring, and spring one end is connected on the side of movable slider, and the other end is connected on the side of the groove of upper slide.In this programme, there is not relative sliding in upper slide and lower skateboard, the thrust larger to both applyings can guarantee the sealing on both composition surfaces, and do not worry improving frictional resistance between the two and wear problem, movable slider horizontal slip in sliding cavity controls the relative dislocation of intercommunicating pore and steel flow port or is communicated with, thus the break-make of control steel flow port; Be connected to spring on movable slider and top shoe side and can apply a lasting pressure to movable slider, ensure that movable slider by the disturbance of general external force, can not keep the position stability of movable slider; Sealing ring and sealing transparent cover can improve the sealing at handle hole place, reduce the possibility of bleed-out.
As preferably, the lower surface of upper slide is provided with annular boss, and annular boss is enclosed in the outside of sliding cavity, and the upper surface of lower skateboard is provided with the annular groove be combined together with annular boss, together with upper slide and lower skateboard are closely pressed together on by bolt.Upper slide and lower skateboard are matched by the annular boss on it and annular groove, make both connect tightr, increase the sealing of sliding cavity; And the relative position of upper slide and lower skateboard can better be determined, thus ensure the epimere of steel flow port and hypomere coaxial at vertical direction; The thrust that bolt can provide lower skateboard enough, the sealing of both guarantees faying face.
As preferably, between upper slide and tundish diapire, be provided with heat insulation tie-plate.In heat insulation tie-plate Absorbable rod tundish, high-temperature molten steel is to the heat radiation at the mouth of a river, reduces the operating temperature at the mouth of a river, improves the service life of each parts in the mouth of a river.
The invention has the beneficial effects as follows: beneficial effect.
