Description
Technical field
The present invention relates to steelmaking technical field, especially a kind of even ladle sliding water gap mechanism for building pressure.
Background technique
Ladle sliding water gap mechanism builds pressure principle currently on the market：It is established in press process in mechanism, on lower skateboard
Steel passing hole cannot be with the steel passing hole on upper slide to just, and lower skateboard is subjected to displacement relative to upper slide and could complete mechanism and build pressure.
Lower skateboard builds pressure by displacement, and the chamotte between upper slide and filling pipe end is not uniform-compression, will cause mud seam uneven thickness, especially
When it is that filling pipe end uses the middle and later periods, borehole enlargement and the contact surface of upper slide sealing station narrow at this time, and mud seam uneven thickness is more
Accident easily occurs, burns out steelmaking equipment.
Steel-making industry cost pressure increases now, in order to survive, in addition in novel aspects making time and material resources, energy conservation drop
Consumption is also very important aspect.Many steel mill's slide plates start even sliding use, and even sliding rate is up to 7 times or more for the country.Slide plate it is more
Secondary even cunning can be energy saving but also reduces production cost for steel mill, but also to the carrier of slide plate --- steel ladle sliding water gap machine
Structure proposes higher technical requirements.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of even ladle sliding water gap mechanisms for building pressure, are able to solve existing
The deficiency of technology makes lower skateboard that can equably establish constant pressure on whole contact surfaces, makes upper slide and filling pipe end
Between sealing chamotte thickness it is uniform, ensure that the stability of mud seam, improve the safety of steel-making, avoid security risk.
In order to solve the above technical problems, the technical solution used in the present invention is as follows：
A kind of even ladle sliding water gap mechanism for building pressure, including base body, base body is interior to be provided with by holding device

It is provided with lower skateboard in ontology, collector nozzle is provided on lower skateboard, is provided on collector nozzle and is lauched muzzle.
Preferably, being provided with safety pin at the top of the rack body.
Preferably, the holding device includes the cam bottom plate and cam cover of upper and lower installation cooperation, cam bottom plate and
Pressing tight plate is provided between cam cover, hingedly there are two fixed teeth at the top of pressing tight plate, between cam bottom plate and cam cover
It is provided with cam, the change in displacement of pressing tight plate is driven by the rotation of cam.
Preferably, the sliding block top-fastener includes the second spring being arranged in rack body, one end of second spring
It is fixed by clamp nut, the other end of second spring is connected with locking push top, and locking push top is in contact with slider body.
It is a kind of it is above-mentioned open the assembly method for pouring the ladle sliding water gap mechanism that the equal perseverance in position builds pressure, by the first oil cylinder and second oil
Cylinder is mounted on base body, slider body is mounted on rack body by sliding block top-fastener, by base body and bracket
Ontology carries out axis and connects；Above-mentioned assembled component is mounted on ladle bottom；Filling pipe end is spread chamotte to be mounted in ladle, it will
Lower skateboard is mounted in slider body, is mounted in base body after upper slide is spread chamotte；By rack body and pedestal sheet
Body is closed, and the second oil cylinder is started, and rack body is pushed to move upwards, and rail wheel and rail contact simultaneously climb up track, track
Wheel belt is moved, and spring pull rod is mobile, and spring pull rod squeezes the first spring by spring planet, and casting mechanism is made to establish pressure automatically.
A kind of even ladle sliding water gap mechanism for building pressure, ladle hang up casting oil cylinder when that will be poured on continuous casting, starting
Hydraulic cylinder, the first oil cylinder pull connecting rod, and connecting rod pulls slider body to open casting mechanism, and molten steel is by refractory material
Hole is flowed into tundish, is poured, and after steel ladle pouring, starting casting oil cylinder pushes connecting rod, and connecting rod pushes
Slider body, sliding block drive lower skateboard movement, close casting mechanism.
Brought beneficial effect is by adopting the above technical scheme：
When pressure of the ladle sliding water gap mechanism between upper lower skateboard is established, lower skateboard is not required to that position occurs relative to upper slide
It moves.This principle makes lower skateboard that can equably establish constant pressure on whole contact surfaces, realize chamotte uniformly by
Power, it is uniform to make to seal chamotte thickness between upper slide and filling pipe end, ensure that the stability of mud seam, reduces molten steel from chamotte seam
Steel accident rate is altered, the safety of steel-making is improved, avoids security risk.
Pressure between slide plate is established when the centering of the slide plate of the resistance to material mouth of a river, conveniently sees the state that chamotte squeezes out at the slide plate mouth of a river, from
And the case where judging chamotte seam.
In the recycling for the slide plate of resistance to material, the Rubbing number of this mode established pressure mode, reduce between slide plate
Shearing force suffered when pressure is built between slide plate, to improve the slide plate service life, reduces cost.
