Abstract
The utility model 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
This utility model relates to a kind of defecator, filters particularly to a kind of gettering for metal continuous cast tundish
Device, belongs to 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.
Utility model content
This utility model is in order to solve problem of the prior art, it is provided that a kind of tundish gettering filter, holds to possess
Continuous gettering filter capacity stabilized steel water flow velocity.
Technical solutions of the utility model are as follows: a kind of tundish gettering filter, including strip matrix, described strip
The top of matrix is provided with raised line along its length, and 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 is respectively
It is positioned at described inlet side and outlet side, described inlet side and outlet side equal apart from the distance of described strip base bottom, institute
Stating strip intrinsic silicon and be provided with strip channel along its length, all described isobaric getterings of described strip channel connection lead to
Road.
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 utility model is, utilizes U-tube principle in isobaric gettering corridor turnover
Mouth two ends constitute identical pressure, stabilized steel water flow velocity；Multiple isobaric gettering corridor are connected by strip channel, when single isobaric suction
During miscellaneous channel blockage, 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.

Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the processing created for the ease of this utility model realizes, and the present embodiment institute is public
The tundish gettering filter opened is combined by channel parts and the core components of capable assembling.Tundish gettering filter after split
Including strip matrix 1, the top of strip matrix 1 is provided with raised line 2 along its length, and raised line 2 is by the top of strip matrix 1
Part is inlet side 11 and outlet side 12, and the distance bottom inlet side 11 and outlet side 12 distance bar shaped matrix 1 is equal.Raised line
2 tops are 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
Put.Strip matrix 1 is internal is provided with the isobaric gettering corridor 4 being arranged in juxtaposition no less than 6, isobaric gettering corridor 4 take the shape of the letter U or
V-arrangement, its two-port lays respectively at inlet side 11 and outlet side 12.Strip matrix 1 is internal is additionally provided with bar shaped along its length
Passage 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
The inwall at the two ends of 12 is provided with some circumferential recess 41, and the axis at two ends and vertical direction angle are 0 °～60 °.Concrete, groove
The cross section of parts is concave structure, processes half slot 4a (Fig. 4 letter of multiple band circumferential recess 41 in the inwall both sides of concave structure
Illustrate only one of them half slot 4a band axial notch 41 after change, reality is all of half slot 4a all band axial notches 41),
