Description
Technical field
The utility model relates to middle water containing opening flow control technique field, particularly relates to a kind ofly to close the stopper rod flow control structure at the mouth of a river by temporary emergency.
Background technology
Stopper-mouth of a river flow control structure is a kind of conventional flow control structure during basket pouring controls, and this structure comprises the nozzle brick with the mouth of a river and the stopper be engaged on the mouth of a river that are arranged on tundish bottom surface.Controlled the aperture at the mouth of a river by the position controlling the relative mouth of a river of stopper, and then control poring rate.But stopper and the mouth of a river are all in the mal-condition of high temperature, fluid scouring, the plug that there will be stopper is washed and diminishes, or even the situation of plug fracture, and at this moment the mouth of a river cannot close normally, and molten steel may be caused to spill accident; Molten steel, when nozzle brick changed by needs, first all can only be discharged and just can carry out by existing stopper-mouth of a river flow control structure, needs to consume the more time, affects production efficiency.
Such as, in existing open file, have that publication number is CN 201895085 U, publication date is the Chinese patent literature of 2011.07.13, disclose a kind of two-seater brick nozzle brick utilizing stopper rod flow control, comprise brick cup and lower brick cup, upper brick cup and lower brick cup inlay fixed Combination by rim of the mouth and female mouth; Described upper brick cup comprises brick body, steel-connecting port, steel runner; Described lower brick cup comprises brick body, steel runner, be wherein provided with at the steel-connecting port place of upper brick cup one with the stopper of steel-connecting port mating shapes.The weak point of this utility model is, because of stopper and nozzle brick go wrong cause the mouth of a river cannot normally closed time, promptly cannot close the mouth of a river; When needing to change nozzle brick, the molten steel in tundish all must be discharged, just can change, affect production efficiency.
Utility model content
The mouth of a river cannot be closed, molten steel in tundish all must be discharged the problem could changed nozzle brick, affect production efficiency by temporary emergency when stopper or nozzle brick damage for solving existing stopper-mouth of a river flow control device, when the utility model provides one and can need to change nozzle brick in the state of emergency, without the need to discharge molten steel in tundish and can the quick closedown mouth of a river can close the stopper rod flow control structure at the mouth of a river by temporary emergency.
To achieve these goals, the technical solution adopted in the utility model is:
A kind ofly can close the stopper rod flow control structure at the mouth of a river by temporary emergency, comprise the mouth of a river be arranged on tundish diapire and the stopper matched with the mouth of a river, tundish diapire is also provided with shutoff ring, shutoff ring is annular and arranges with the mouth of a river is concentric, the internal diameter of shutoff ring is greater than the diameter at the mouth of a river, the upper surface of the upper surface height delivery port of shutoff ring, is provided with the closing cap matched with shutoff ring near above the plug of stopper.By the shutoff ring in mouth of a river arranged outside annular, and the closing cap coordinated with it is set on stopper, like this plug of stopper and the mouth of a river go wrong cannot normally close time, the object reaching and close the mouth of a river can be coordinated by closing cap and shutoff ring, so namely, the accident that mouth of a river accidental destruction causes molten steel to flow out effectively can be avoided, nozzle brick can also changed quickly and easily, and not need to discharge molten steel whole in tundish.
As preferably, it is semicircular annular groove that the upper surface of shutoff ring is provided with cross section, and the lower surface of closing cap is provided with the annular boss matched with described annular groove.Matched by the annular groove on shutoff ring and the annular boss on closing cap, add both contact area and sealing reliabilities, after making both closed, can better ensure that molten steel does not leak out.
As preferably, between closing cap upper surface and the outer circumference surface of stopper, be provided with some reinforcements.Reinforcement can increase the bonding strength of closing cap and stopper, improves the service life of this structure.
As preferably, reinforcement has four, and is circumferentially being uniformly distributed.Equally distributed four reinforcements make being connected firmly between this closing cap and stopper, uniform force, improve whole service life.
The beneficial effects of the utility model are: can the state of emergency and need change nozzle brick time, without the need to discharge molten steel in tundish and can the quick closedown mouth of a river can temporary emergency close the mouth of a river.
