Abstract
The invention discloses a kind of tundish gettering filter, including strip matrix, the top of strip matrix is provided with raised line along its length, the top of strip matrix is divided into inlet side and outlet side by raised line, strip intrinsic silicon is provided with some isobaric gettering corridor being arranged in juxtaposition, the two-port of isobaric gettering corridor lays respectively at inlet side and outlet side, the distance of inlet side and outlet side distance bar shaped base bottom is equal, strip intrinsic silicon is provided with strip channel along its length, all isobaric gettering corridor of strip channel connection.The isobaric gettering corridor import and export pressure at both sides of this tundish gettering filter is equal, and molten steel flow speed is stable, and a plurality of isobaric gettering corridor is interconnected, and decreases channel blockage impact.
Description
Technical field
The present invention relates to a kind of defecator, particularly to a kind of gettering filter for metal continuous cast tundish, belong to
In technical field of metallurgical equipment.
Background technology
Tundish is the intermediate link of continuous-casting steel-making production procedure, and the major function of tundish includes shunting action, even waters
Effect, decompressing effect, protective effect and removal of contamination effect.Wherein tundish filter is typically made up of refractory material
Porous filter plate, when molten steel flows to screen plate, the impurity carried secretly is adsorbed by hole wall, reaches the effect of removal of contamination.The most normal
The slag blocking wall of height setting, dam is used to carry out contaminant filter.But the filter of these prior aries be generally of with
Lower shortcoming: gettering ability is more weak, impurity absorption ability in molten steel, slag blocking wall dross amount is few, need to frequently change to ensure to use
Effect, the most easily makes nozzle blocking, impact produce.Slag blocking wall constitutes the runner of height complications and the straight of porous filter plate
String holes road is all difficult to stabilized steel water flow velocity, along with steel drum pour steel produces impact.
Summary of the invention
The present invention is to solve problem of the prior art, it is provided that a kind of tundish gettering filter, persistently inhale to possess
Miscellaneous filter capacity stabilized steel water flow velocity.
Technical solution of the present invention is as follows: a kind of tundish gettering filter, including strip matrix, described strip matrix
Top be provided with raised line along its length, the top of strip matrix is divided into inlet side and outlet side by described raised line, described
Strip intrinsic silicon is provided with some isobaric gettering corridor being arranged in juxtaposition, and the two-port of described isobaric gettering corridor lays respectively at
Described inlet side and outlet side, described inlet side and outlet side are equal apart from the distance of described strip base bottom, described length
Bar shaped intrinsic silicon is provided with strip channel along its length, all described isobaric gettering corridor of described strip channel connection.
Preferably, the bottom of all described isobaric gettering corridor of described strip channel connection.
Preferably, described isobaric gettering corridor is U-shaped or V-arrangement passage.
Preferably, the inwall of one end that described isobaric gettering corridor is positioned at inlet side is provided with some circumferential recess.
Preferably, the inwall of one end that described isobaric gettering corridor is positioned at outlet side is provided with some circumferential recess.
Preferably, the axis of one end that described isobaric gettering corridor is positioned at inlet side is 0 °~60 ° with vertical direction angle.
Preferably, the axis of one end that described isobaric gettering corridor is positioned at outlet side is 0 °~60 ° with vertical direction angle.
Preferably, described isobaric gettering corridor is no less than 6.
Further, described raised line top is provided with groove along its length.
The advantage of technical scheme provided by the present invention is, utilizes U-tube principle to import and export two at isobaric gettering corridor
End constitutes identical pressure, stabilized steel water flow velocity;Multiple isobaric gettering corridor are connected by strip channel, when single isobaric gettering leads to
During road blocking, molten steel still can be flowed out by the outlet of other isobaric gettering corridor, decreases because blocking affects molten steel flow speed;Raised line
Top arranges groove and is easy to gettering filter position in tundish and fixes, and simple in construction is easy installation and reliable.

Fig. 1 is apparatus of the present invention structure schematic top plan view.
Fig. 2 is that the AA of Fig. 1 is to cross-sectional schematic.
Fig. 3 is core components structure schematic top plan view.
Fig. 4 is channel parts structure schematic top plan view.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described, but not as a limitation of the invention.
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the processing for the ease of the invention realizes, disclosed in the present embodiment
Tundish gettering filter is combined by channel parts and the core components of capable assembling.Tundish gettering filter after split includes
Strip matrix 1, the top of strip matrix 1 is provided with raised line 2 along its length, and the top of strip matrix 1 is divided by raised line 2
Equal for the distance bottom inlet side 11 and outlet side 12, inlet side 11 and outlet side 12 distance bar shaped matrix 1.Raised line 2 pushes up
Portion is provided with groove 3 along its length, and this groove 3 can be used for slag blocking wall internal with tundish and coordinates with Fixed-Filter position.
Strip matrix 1 is internal is provided with the isobaric gettering corridor 4 being arranged in juxtaposition no less than 6, and isobaric gettering corridor 4 takes the shape of the letter U or V
Shape, its two-port lays respectively at inlet side 11 and outlet side 12.Strip matrix 1 inside is additionally provided with bar shaped along its length and leads to
Road 5, strip channel 5 connects the bottom of all isobaric gettering corridor 4.Isobaric gettering corridor 4 is positioned at inlet side 11 and outlet side 12
The inwall at two ends be provided with some circumferential recess 41, the axis at two ends and vertical direction angle are 0 °~60 °.Concrete, groove portion
The cross section of part is concave structure, processes half slot 4a (Fig. 4 simplification of multiple band circumferential recess 41 in the inwall both sides of concave structure
After illustrate only one of them half slot 4a band axial notch 41, reality is all of half slot 4a all band axial notches 41), core
The both sides, lower end of parts also process the half slot 4b of band axial notch 41, and groove 3 is offered at the top of core components along its length.
