On the outer shroud cell wall of spiral lifting dish, be arranged with four handles.
In upper frame and travelling carriage, be equipped with the jack for compressing upper and lower sliding plate brick.
As shown from the above technical solution, molten steel flows in tundish by steel ladle sliding water gap unit, steel ladle sliding water gap listUnit is made up of the first slide gate mechanism and long nozzle mechanism, and the long nozzle in long nozzle mechanism directly stretches in tundish,Ladle is during to basket pouring, and molten steel enters tundish from the liquid steel level below of tundish, makes liquid steel level steady, reallyProtect slag floating and swim on liquid level, the slag content of the tapping hole place molten steel of tundish is few, prevents that slag inclusion molten steel from injectingIn foundry goods, produce surface or the internal flaws such as slag inclusion, crackle; Tundish slide gate nozzle unit is by driving mechanisms control theThe folding at the two slide gate mechanism mouths of a river, molten steel flows in foundry goods by the mouth of a river; The first slide gate mechanism and second slidesThe operation principle of gate mechanism is identical, i.e. slide plate moving linearly slides lower slide brick, the mouth of a river of upper and lower sliding plate brickWhen centering, slide gate mechanism is opened completely, molten steel flow maximum, the water of the porous plug in lower slide brick and upper slide brickWhen mouthful centering, slide gate mechanism is closed, and metal bellows or Argon pipe be blowing argon gas in the mouth of a river of sliding plate brick upwards, preventsMolten steel solidification.
In steel ladle sliding water gap unit, the lower mouth of a river in the long nozzle in long nozzle mechanism and the first slide gate mechanism connectsLogical, the upper end of the lower end at the lower mouth of a river and long nozzle opening is all turbination, facilitates the installation and removal of long nozzle, long waterMouth is fixed on long nozzle below by spiral lifting dish and pallet, and spiral lifting dish is threaded with pallet, and pallet is fastened onIn bracing frame, bracing frame is fixed on suspension bracket, therefore rotates spiral lifting dish and can promote or transfer long nozzle, long nozzleInstallation and removal all do not need other assistive devices, and utilize lifting that the operation principle of jack makes long nozzle moreAdd laborsaving.
Travelling carriage is provided with backstay, and backstay inserts in the location blind hole of pallet, guarantees pallet standard in the time that long nozzle promotesDetermine position and can move together with travelling carriage, after long nozzle is enclosed within on the lower mouth of a river, the lower mouth of a river and backstay drive long water jointlyMouth mechanism slides in linear pattern slideway with travelling carriage; The bottom surface of suspension bracket is provided with limiting plate, and backstay inserts determining of palletPosition blind hole after, limiting plate carries out spacing to pallet, guarantee long nozzle be positioned at the lower mouth of a river under, ensure installation accuracy.
The first Argon mechanism is used for to slide gate mechanism and long nozzle mechanism blowing argon gas, and argon gas is by porous plug and ventilativeRing enters respectively in filling pipe end and long nozzle, realizes the protection of argon envelope, prevents that molten steel condensation slagging scorification adhesion, air from immersing and steelWater leaks outside.
The T-shaped front end of connecting rod snaps in the T-shaped groove of slide plate, and rear end is threaded with connector, and locks by locking nutTightly, between connecting rod and slide plate and connector, be connected firmly and easy accessibility, rod rear end is threaded and makes with connectorThe mounting distance of connecting rod is adjustable; Sleeve, sealing ring, gland and outer seat form the sealing device of connecting rod, between sleeve and connecting rodGap coordinates, and plays guiding and supporting role and can prevent that connecting rod from pulling, and sealing ring is V-type combined seal ring, plays sealing and doesWith, gland compresses V-type combined seal ring, and when after the wearing and tearing of V-type combined seal ring, tighten gland and can carry out sealing compensation,Ensure sealing effectiveness, guarantee that pouring molten steel carries out under vacuum environment; Spacer pin is set on connecting rod, plays link motion spacingEffect, the anti-turn screw on connecting rod is stationary links behind connecting rod location, prevents that connecting rod from rotating.
Hydraulic cylinder is fixed on support, and the square flange of its front end plays the effect of axial limiting and radial rotation, hydraulic cylinderAfter working long hours, there is slight change in its position, and the axis of piston rod is departed from the axis of connecting rod slightly, if pistonBar and connecting rod are connected and can produce shear stress, because the piston rod of hydraulic cylinder is flexibly connected with connector, and therefore hydraulic cylinderTrickle change in location can not affect the motion of connecting rod, ensure that connecting rod and the motion of slide plate are positioned on straight line, the slide plate beginningEventually in best operational position.
Pouring molten steel device is in the time of closed condition, and the mouth of a river centering of the porous plug in Argon mechanism and upper slide brick, ensuresArgon gas blow to the molten steel in the upper slide brick mouth of a river by porous plug, promote that flowing of molten steel do not solidified, even liquid steel temperature,Remove the field trash in molten steel; Sealing gasket between slide plate and lower slide brick can block the excessive and outside air of argon gas and enter,Avoid impurity to enter in molten steel.
In pouring molten steel device provided by the invention, long nozzle mechanism does straight reciprocating motion in molten steel with travelling carriage, willThe even water conservancy diversion of molten steel, in tundish, can effectively prevent that molten steel from splashing, and avoids molten steel to contact generation secondary oxidation with air,Improve the clarity of molten steel, ensured the quality of foundry goods; The second slide gate mechanism is by regulating the upper and lower sliding plate brick mouth of a riverThereby folding regulate the size of molten steel flow, control molten steel tap, fundamentally eliminated the cast of stopper rod of tundish formulaThe variety of issue that control mode is brought, and favorable sealing property, the motion stabilization of connecting rod and slide plate, precisely, this deviceSimple in structure, easy accessibility, casting quality is good.
