Technical field
The present invention relates to continuous casting tundish, more particularly, to a kind of tundish with sampling steel interface.
Background technology
Tundish is the refractory material containers used in mini-mill steelmaking, accepts first to pour, from ladle, the steel getting off
Then molten steel is assigned to crystallization in crystallizer by middle water containing opening by water again.Molten steel, need to be to wherein during tundish
Molten steel be sampled detect, to determine the amount of the phosphorus content in molten steel, oxygen content and other compositions.Commonly used in the prior art
The method of sampling steel is to scoop formula by spoon or removable independent sampler takes out molten steel, such side from tundish
There are a lot of problems in method, such as take can be mixed into while molten steel be covered in molten steel upper strata slag blanket, take out molten steel can be by the air
Oxygen aoxidized, the molten steel component that obtains in diverse location can variant it is impossible to the composition of molten steel at the accurate response mouth of a river,
Impact testing result.
For example, in existing open file, notification number is had to be cn 202599708 u, the day for announcing is 2012.12.12
Chinese patent literature, discloses a kind of Steel liquid sampler, described sample cup is cylinder, and its center has funnel hole；Described
Plug profile is truncated cone, and its taper is corresponding with the funnel hole taper of sample cup.This technical scheme is disadvantageous in that, takes
The slag blanket being covered in molten steel upper strata can be mixed into, the molten steel taking out can be aoxidized by the oxygen of in the air, impact inspection while molten steel
Survey result.
Content of the invention
In addition need to prepare independent sampler for solving existing tundish carrying out sampling steel, sampling is inconvenient,
The molten steel obtaining easily is mixed into the problem of slag blanket material, the present invention provides that a kind of sampling is convenient, molten steel that is obtaining will not be mixed into miscellaneous
Matter, obtain molten steel will not oxidation by air and obtain molten steel with flow out tundish crystallized molten steel component identical tool
There is the tundish of sampling steel interface.
To achieve these goals, the technical solution used in the present invention is:
A kind of tundish with sampling steel interface, including the mouth of a river being arranged on tundish diapire, diapire also sets

The epimere in face is additionally provided with the head piece of the lateral wall running through water conservancy diversion plug and flow-guiding channel, and the medial wall of sample tap brick cup covers in head piece
On, head piece has two, and is symmetrically distributed on the side of water conservancy diversion plug.Sampling steel detection main purpose is controlling stream outlet
Whether the composition of molten steel at place meets the requirements, and the present invention passes through to arrange sample tap near the mouth of a river, can be easily and fast from obtaining
Obtain the molten steel near the mouth of a river, molten steel component herein can accurately reflect the one-tenth that will flow out the molten steel that the mouth of a river is poured into a mould
Point, be conducive to the accurate of subsequent analysis result；This programme adopts the thief hole directly arranging sampling steel in middle containment wall, and
It is not to be inserted into sampling under slag blanket with other sampler from the centre side of wrapping, in the molten steel so obtaining, slag blanket will not be mixed into
Material, the composition of molten steel, closer to the molten steel at the mouth of a river, is conducive to the analysis of molten steel component and takes appropriate measures, by leading
Stream beyond the Great Wall lower slider controlling opening and closing convenient and swift of sampling passage；Head piece is symmetrical, and structure stress is reasonable, and not
Easily block..
Preferably, the lower section of water conservancy diversion plug has been provided with probe tube, the lateral surface of probe tube is provided with connection screw thread, probe tube
Linked together by fixture block with water conservancy diversion plug and be connected.It is provided with connection screw thread outside probe tube, external container can be connected, realize envelope
Close sampling, acquired molten steel will not ingress of air, be unlikely to oxidized impact testing result.
Preferably, being provided with spring between fixture block and sample tap brick cup.Spring can pull down after the sampling is complete automatically
Return water conservancy diversion plug, thus head piece is enclosed on the medial wall of sample tap brick cup, reach the purpose of closing head piece.
Preferably, being provided with seal washer between water conservancy diversion plug and probe tube.Seal washer can make water conservancy diversion plug and probe tube
Between be completely embedded, occur without bleed-out.
The invention has the beneficial effects as follows: from tundish obtain molten steel easy to operate, obtain molten steel will not be mixed into miscellaneous
Matter, will not oxidation by air and with flow out the mouth of a river at molten steel component identical, so that sampled molten steel is just accurately reflected
In the composition flowing out the molten steel that the mouth of a river is crystallized, testing result is accurate.
