Description
Technical field
The present invention relates to continuous casting tundish, particularly relate to a kind of tundish with sampling steel interface.
Background technology
Tundish is the refractory material containers used in mini-mill steelmaking, first accepts to water from ladle the molten steel got off, and then by middle water containing opening, molten steel is assigned to crystallization in crystallizer.Molten steel, in the process of tundish, need carry out sampling to molten steel wherein and detect, to determine the amount of phosphorus content, oxygen content and other compositions in molten steel.The method of sampling steel conventional in prior art is, formula is scooped or removable independent sampler takes out molten steel from tundish by spoon, there is a lot of problem in such method, the slag blanket being covered in molten steel upper strata as being mixed into while getting molten steel, the molten steel of taking-up can be oxidized by the oxygen in air, the molten steel component that obtains at diverse location can be variant, can not the composition of molten steel at accurate response mouth of a river place, affect testing result.
Such as, in existing open file, have that notification number is CN 202599708 U, the day for announcing is the Chinese patent literature of 2012.12.12, disclose a kind of Steel liquid sampler, described sample cup is cylindrical, 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.The weak point of this technical scheme is, can be mixed into while getting molten steel be covered in molten steel upper strata slag blanket, taking-up molten steel can be oxidized by the oxygen in air, affect testing result.
Summary of the invention
Need to prepare independently sampler in addition for solving existing tundish carrying out sampling steel, the problem that sampling is inconvenient, molten steel that is that obtain easily is mixed into slag blanket material, the invention provides a kind ofly to sample conveniently, the molten steel that obtains can not be mixed into impurity, the molten steel that obtains oxidation by air and the molten steel obtained and outflow tundish can not carry out the identical tundish with sampling steel interface of the molten steel component of crystallization.
To achieve these goals, the technical solution used in the present invention is:
A kind of tundish with sampling steel interface, comprise the mouth of a river be arranged on tundish diapire, diapire is also provided with installing hole with the level, installing hole is arranged near the mouth of a river, the sample tap brick cup that longitudinal section is " T " font is provided with in installing hole, through hole is provided with in the middle of sample tap brick cup, the water conservancy diversion plug that can slide up and down along through hole is provided with in through hole, the longitudinal section of water conservancy diversion plug is " T " font, water conservancy diversion is provided with flow-guiding channel beyond the Great Wall, flow-guiding channel is the blind hole of opening on water conservancy diversion plug lower surface, the epimere of water conservancy diversion plug side is also provided with and runs through the lateral wall of water conservancy diversion plug and the head piece of flow-guiding channel, the madial wall of sample tap brick cup covers on head piece, head piece has two, and be symmetrically distributed on the side of water conservancy diversion plug.Sampling steel detection main purpose is whether the composition of the molten steel of control flow check water outlet meets the requirements, the present invention by arranging sample tap near the mouth of a river, can easily and fast from the molten steel obtained near the mouth of a river, molten steel component herein can reflect the composition carrying out the molten steel poured into a mould by the outflow mouth of a river accurately, is conducive to the accurate of subsequent analysis result; This programme adopts the thief hole directly arranging sampling steel on tundish wall, instead of to be inserted under slag blanket from the centre side of wrapping with other sampler and to sample, slag blanket material can not be mixed in the molten steel obtained like this, the composition of molten steel is closer to the molten steel at mouth of a river place, be conducive to the analysis of molten steel component and take appropriate measures, by water conservancy diversion beyond the Great Wall lower slider to control to sample the open and close of passage convenient and swift; Head piece is symmetrical, and structure stress is reasonable, and not easily blocks.。
As preferably, the below of water conservancy diversion plug has been provided with probe tube, and the lateral surface of probe tube is provided with connecting thread, and probe tube and water conservancy diversion plug are linked together by fixture block and be connected.Be provided with connecting thread outside probe tube, can connect external container, realize closing sampling, acquired molten steel can not ingress of air, and being unlikely to oxidized affects testing result.
As preferably, between fixture block and sample tap brick cup, be provided with spring.Spring can retract downwards water conservancy diversion plug after the sampling is complete automatically, thus is enclosed in by head piece on the madial wall of sample tap brick cup, reaches the object of closed head piece.
As preferably, between water conservancy diversion plug and probe tube, be provided with seal washer.Seal washer can make the connection between water conservancy diversion plug and probe tube tight, does not occur bleed-out.
The invention has the beneficial effects as follows: the molten steel that is easy to operate, that obtain obtaining molten steel from tundish can not be mixed into impurity, can not oxidation by air and identical with the molten steel component of stream water outlet, sampled molten steel is reflected accurately and is flowing out the composition that the molten steel of crystallization is carried out at the mouth of a river, testing result is accurate.
