Description

Elastic floating shingling type sliding gate

The present invention relates to be applicable to the slide gate nozzle of metallurgy industry in order to the control flow of molten metal; Be specially adapted to the slide gate nozzle of control molten steel flow on bottom pour ladle and the conticaster.

The present invention is based on the Mei Taken type slide gate nozzle of popular in the world Switzerland Mei Taken company (MeTaCon) production and the Fu Luokang type slide gate nozzle that Britain Fu Luokang factory (FLo-Con) produces.

General slide gate nozzle, especially for the slide type slide gate nozzle of bottom pour ladle, on functional configuration mostly by upper slide assembly, lower skateboard assembly, lower skateboard holds down assembly and the slide plate thrust component is formed.The upper slide assembly by upper slide seat, upper slide form, also be welded with on the upper slide seat hinge seat, upper slide seat and steel plate at the bottom of the bottom pour ladle bag with bolt firmly be connected, lay fire clay in the upper slide seat, the cementation that utilizes fire clay with upper slide be bonded in the upper slide seat, upper slide be a plate face one through hole is arranged refractory brick, this through hole and casting ladle bag at the bottom of molten steel drop down the perforation of portalling; The lower skateboard assembly is made up of lower skateboard slide and lower skateboard, and downslide integrated circuit board jail is in the hollow part of lower skateboard slide, and lower skateboard also is the refractory brick that a plate face has a through hole, and lower skateboard plate face through hole face diameter is equal to or greater than upper slide plate face through-hole diameter; The slide plate thrust component can be an electric pushrod, hydraulic pressure pushes away cylinder, it also can be the hand lever augmentor, the lower skateboard of various slide gate nozzles holds down assembly, and mode is different to differ greatly because of compressing, for ease of changing lower skateboard, a hinged rigid carriers of general all employings and upper slide seat is come roof pressure lower skateboard assembly, the mode that compresses of the slide gate nozzle that the difference part is is directly carriage to be pulled to the upper slide assembly by several eyelet bolts that are hinged on the upper slide seat, depress skateboard component by the carriage rigid top, make that slide plate fits tightly up and down, the Mei Taken type slide gate nozzle produced of Switzerland for example, this mode that compresses is not considered in working order down each part expanded by heating and change in size of taking place in addition, thrust between slide plate is difficult for aligning best user mode up and down, nor slide plate plate face is fitted fully, because its carriage can only be around the swing that does not have others with the hinged hinge swing of upper slide seat.And the Fu Luokang type slide gate nozzle that Britain produces, an its rigid case beam also is that the hinged form of employing and upper slide seat also can only be around the hinge swing hinged with the upper slide seat, two groups of air springs (or other heat-resisting spring) and a carriage only between carriage and lower skateboard assembly, have been increased, the air spring Support bracket, the lower skateboard slide can reciprocatingly slide on carriage, the other end of Big bracket is upwards pressed skateboard component with carriage together with the lower skateboard assembly by being hinged on the hinge of three on upper slide seat clamp, make and compress applying up and down slide plate plate surface elastic, owing to used spring, Gu this can compensate each change in size of part expanded by heating face generation in addition, but upper slide causes upper slide plate face tilt owing to being bonded in fire clay in the upper slide seat, the decrement of two groups of air springs of Support bracket is also just different, therefore the force action line of two groups of air springs can not guarantee that next is surely by upper slide plate face through hole in working order, cause, lower skateboard binding face through hole is inhomogeneous with the thrust on the limit, still have bleed-out hidden danger, to drop down passage apart from molten steel near excessively for the layout of air spring in addition, and condition of work is abominable, air spring as rapid wear, except that price is more expensive, dependence on import still mostly at present.During actual production was used, the frequent card of three hinge clamps did not advance because the upper slide height differs, the operation effort.

The object of the present invention is to provide and a kind ofly guarantee that it is equally distributed novel slide gate nozzle in bore periphery that slide plate plate face up and down descend the thrust that elastic compression is fitted and the lower skateboard plate is faced upper slide plate face through hole in working order.

The present invention is achieved in that a kind of elastic floating compression type slide gate nozzle that is applicable to metallurgy industry in order to the control flow of molten metal, be specially adapted to the slide gate nozzle of control molten steel flow on bottom pour ladle and the conticaster, by the upper slide assembly, the lower skateboard assembly, lower skateboard holds down assembly and the slide plate thrust component is formed, the upper slide assembly is by upper slide seat (1), upper slide (2), two hinge seats (3) (3 ') that are welded on upper slide seat (1) one end are hinged on upper slide seat (1), the eyelet bolt of the other end (4), (4 ') and and the matching used holddown spring of eyelet bolt (4) (4 ') (5) (5 ') clamp nut (6) (6 ') composition.Upper slide seat (1) has a through hole with steel plate (7) at the bottom of the bottom pour ladle bag of depositing motlten metal by upper slide (2) the plate face central authorities that bolt firmly is connected, is bonded in the upper slide seat (1) with fire clay, drops down to portal with the motlten metal of depositing molten metal container to connect.The lower skateboard assembly by lower skateboard slide (8) and the lower skateboard slide (9) that is fixed on lower skateboard slide (8) hollow part form, lower skateboard (9) plate face central authorities have through hole, aperture to equal or are slightly larger than upper slide (2) plate face through hole, lower skateboard holds down assembly and is made up of two separate camber beams (10) (10 ') that are hinged on the hinge seat (3) (3 ') on the upper slide seat (1) respectively and a carriage (11).The middle part of camber beam (10) (10 ') respectively has a through hole with fixing hinge (12) (12), carriage (11) is hinged on the middle part of camber beam (10) (10 ') by hinge (12) (12 '), the common plane of two hinges (12) (12 ') axis is by upper slide (2) plate face through hole down in working order, and carriage (11) can freely swing around hinge (12) (12 '), on carriage (11), the twice parallel groove is arranged, lower skateboard slide (8) can axially reciprocatingly slide at the chute upper edge camber beam on the carriage (11), the slide plate thrust component can be an electric pushrod, hydraulic pressure pushes away cylinder, it also can be the hand lever augmentor, embodiment adopts the hand lever augmentor.Special character of the present invention is: two the separate camber beams (10) (10 ') that are hinged on the upper slide seat (1) pass through hinge (12) (12 ') together support carriage (11), the hole of carriage (11) both sides belongs to the cooperation in gap greatly with cooperating of hinge (12) (12 '), when two camber beams (10) (10 ') respectively by the eyelet bolt in the upper slide assembly (4) (4 '), when holddown spring (5) (5 ') and clamp nut (6) (6 ') are pressed to the upper slide assembly, (upper slide that causes (a 2) plate face position is to indefinite in 10 although upper slide (2) is owing to be bonded in the upper slide seat with fire-resistant mud, the plate face of the lower skateboard (9) in the lower skateboard assembly that floats on the carriage (11) can both be adaptively fitted tightly with the plate face of upper slide (2), again because the common plane of two hinges (12) (12 ') axis of Support bracket (11) is down by upper slide (2) plate face through hole in working order, so the force action line of roof pressure lower skateboard (9) is also by upper slide (2) plate face through hole, when upper slide (2) through hole and lower skateboard (9) when through hole staggers, be that slide gate nozzle is when being in closed condition, thrust on upper slide (2) bore periphery is uniform, therefore just can not produce molten steel from spilling next phenomenon between upper slide (2) and the lower skateboard (9).In addition holddown spring (5) (5 ') be arranged in away from molten steel drop down the other end of camber beam (10) (10 ') of passage so condition of work will compared with Britain produce the air spring of Fu Luokang type slide gate nozzle much better, add afterburning this favorable factor of cross bar, therefore can reduce the cost of manufacture of holddown spring (5) (5 ') greatly.
