Abstract
The utility model relates to a ladle bottom flexibility sealing diversion cover device comprises a ladle bottom sealing cavity which is welded with the ladle bottom and a flexibility diversion cover device which is arranged above a vacuum chamber. The ladle bottom sealing cavity comprises all the sliding gate mechanisms comprising a hydraulic cylinder, a hermetic door which is arranged on the side of the sealing cavity and is opposite to the hydraulic cylinder, a packing ring which is positioned at the side of the sealing cavity and is embedded on the hermetic door, and a water-cooling flange which is welded on the peripheral of the sliding gate of the ladle bottom under the sealing cavity. The flexibility diversion cover device comprises a water-supply cooling box of the flexibility diversion cover which is capable of covering the sliding gate of the ladle, a packing ring of the sealing flange which is arranged on the top end of the water-supply cooling box, a diversion pipe which is arranged above the vacuum chamber, an accordion pipe which is arranged on the outer face of the diversion pipe and a dish-type spring. Canceling a middle ladle, the utility model uses a flexibility sealing diversion cover device to replace, thereby the secondary pollution and air inlet which are caused when the fluid passes the middle ladle are avoided.
Description
Technical field
The utility model relates to the molten steel vacuum casting treatment facility of metallurgy industry, flexible seal water conservancy diversion covering device at the bottom of the ladle that particularly a kind of vacuum casting is used.
Background technology
Existing vacuum casting processing procedure is to settle a middle ladle above being placed with the vacuum chamber of ingot mould, will inject middle ladle earlier through the molten steel in the ladle of the degassing, and the molten steel in the ladle injects ingot mould through the water conservancy diversion cover again.
Adopt this processing method, when molten steel can cause secondary pollution and air-breathing through middle ladle.
Summary of the invention
Task of the present utility model provides flexible seal water conservancy diversion covering device at the bottom of a kind of improved ladle, and it has solved existing vacuum casting and has handled because of ladle in the middle of placing and cause secondary pollution and air-breathing problem.
The technical solution of the utility model is as follows:
Flexible seal water conservancy diversion covering device at the bottom of a kind of ladle, it contains steel ladle sliding water gap mechanism, and it comprises annular seal space at the bottom of the ladle that connects with the ladle back welding, and the flexible water conservancy diversion covering device that is installed in the vacuum chamber top;
Annular seal space comprises whole slide gate mechanisms of hydraulic cylinder at the bottom of the described ladle, and comprise and be installed on annular seal space side, the hermatic door relative with hydraulic cylinder, be positioned at the annular seal space side and be inlaid in sealing ring on the hermatic door, and be welded on water-cooling flange under the annular seal space of ladle bottom slide gate mechanism periphery;
Described flexible water conservancy diversion covering device comprises that the flexible water conservancy diversion that can cover steel ladle sliding water gap puts the water-cooled box, and the sealing ring on the sealing flange of last water-cooled box upper end is positioned at the mozzle of vacuum chamber top, and the bellows and the butterfly spring that are installed in the mozzle outside.
The utility model has been cancelled middle ladle, substitutes with a flexible seal water conservancy diversion covering device.When driving hangs molten steel back stall bag when in place, vertical microdisplacement and level trace angle that this flexible seal water conservancy diversion covering device can adapt to steel ladle change, and finish sealing between steel ladle and the vacuum chamber, steel ladle sliding water gap mechanism is included in fully in the annular seal space of flexible seal water conservancy diversion covering device.The medium flexible pipe can seal snap joint by the next door and be connected with annular seal space medium flexible pipe outward.Open steel ladle sliding water gap, the molten steel in the ladle is through the water conservancy diversion cover in the flexible seal water conservancy diversion covering device, the ingot mould in the vacuum chamber that reinjects.
The utility model has compared with prior art been avoided secondary pollution that molten steel causes through middle ladle and air-breathing.
Description of drawings
Accompanying drawing is the structural representation of flexible seal water conservancy diversion covering device at the bottom of a kind of ladle of the present utility model.
The specific embodiment
Referring to accompanying drawing, the utility model is a flexible seal water conservancy diversion covering device at the bottom of a kind of ladle, and it contains steel ladle sliding water gap mechanism 5, comprises annular seal space 11 and flexible water conservancy diversion covering device 2 at the bottom of the ladle, annular seal space 11 connects with ladle 1 back welding at the bottom of the ladle, and flexible water conservancy diversion covering device 2 is installed in vacuum chamber 3 tops.
Annular seal space 11 is provided with water-cooling flange 14 under hermatic door 12, sealing ring 13 and the annular seal space at the bottom of the ladle.Annular seal space 11 is welded in the ladle bottom side and contains hydraulic cylinder 4.Hermatic door 12 is installed in annular seal space side and relative with hydraulic cylinder 4.In the annular seal space side, sealing ring 13 is inlaid on the hermatic door 12.Water-cooling flange 14 is welded on ladle bottom slide gate mechanism 5 peripheries under the annular seal space.
Flexible water conservancy diversion covering device 2 is equipped with flexible water conservancy diversion and puts water-cooled box 22, sealing ring 21, mozzle 25, bellows 23 and butterfly spring 24.Flexible water conservancy diversion puts water-cooled box 22 can cover steel ladle sliding water gap.Sealing ring 21 is placed in flexible water conservancy diversion and puts on the sealing flange of water-cooled box 22 upper ends.Mozzle 25 is positioned at vacuum chamber 3 tops, the inwall coating refractory coating of mozzle 25, and mozzle 25 can often be changed.Bellows 23 and butterfly spring 24 are installed in the outside of mozzle 25, and vertical microdisplacement when bellows 23 can allow ladle in place and level trace angle change, and butterfly spring 24 can produce the sealing pretightning force.
Mozzle 25 is installed in the bellows 23, can protect bellows 23 to exempt from heat radiation on the one hand, and the molten steel that reducible on the other hand beam spreading is penetrated makes molten steel successfully inject ingot mould.The butterfly spring 24 that produces pretightning force can be when ladle be in place, and the sealing ring 21 that flexible water conservancy diversion is put on the water-cooled box 22 upper end sealing flanges is close to water-cooling flange 14 under the annular seal space.
During maintenance, open and be positioned at the other hermatic door 12 of annular seal space 11 sides, i.e. the keying hydraulic cylinder 4 of dismantled and assembled slide gate nozzle at the bottom of the ladle.Be welded on water-cooling flange 14 under the annular seal space at the bottom of the ladle and do not influence dismounting steel ladle sliding water gap.
