Description
The present invention relates to motlten metal, particularly the processing of molten steel.The present invention be more particularly directed to a kind of impact pad for tundish, promptly a usefulness refractory material is made, and is placed on the bottom surface of a tundish, accepts to inject from a steel ladle parts of the motlten metal stream of this tundish.The present invention is used in particular for the continuous casting of steel.
The disclosed a kind of impact pad for tundish of international patent application No.WO96/14951 (FOSECO) comprises that one can bear the body that the refractory material that contacts with molten steel in the tundish is made.This cushion pad body comprises that one has the bottom of a shock surface, a lateral wall that stretches upwards from this shock surface to be connected with this sidewall with one, limits the end face of an opening.Have in the end face one with the ring part of shock surface almost parallel, be roughly the right angle between the interior ring part of sidewall and shock surface and sidewall and end face.This cushion pad can improve the time of staying of molten steel in tundish, thereby guarantees to be removed after unnecessary inclusion has the enough time to float to molten steel surface.
The disclosed a kind of impact pad for tundish of international patent application No.WO97/37799 (FOSECO) comprises that one can bear the body that the refractory material that contacts with molten steel in the tundish is made.This cushion pad body comprises that one has the bottom of a molten steel shock surface, and one is that stretch upwards from this shock surface and around the lateral wall of this bottom stretching, extension fully it is surrounded.One annular body that is connected with sidewall is divided formation and shock surface almost parallel, qualification one is for the end face of the opening of molten steel injection, the bottom surface and the inside surface of side wall of annular solid part limit a dimple, and this dimple has a undercut portions along shock surface periphery and continuous stretching, extension above shock surface.The part of end face is lower than the remainder of end face, and the cross section of the dimple of this part below of end face is littler than the remainder of dimple.This cushion pad can be used to improve the flowability of molten steel in the elongated shape tundish especially, and molten steel injects from an end of this tundish, and this of molten iron or each outlet are at the opposite end of this tundish.The position of this cushion pad is placed to and makes that the end wall other with injecting molten steel than lower part of this end wall is adjacent, thereby the feasible molten steel preferential flow that rebounds from cushion pad is to this end wall.This can reduce the surface eddy that generates in the tundish greatly, thereby improves stream, generates the more steel of cleaning.
Merit attention and since change a cushion pad design generally can produce the influence that can't predict in a certain respect to the hydrodynamics of whole tundish, therefore to satisfy the new impact pad for tundish of being scheduled to specific (special) requirements be unusual complexity in design.The inventor's purpose is a kind of new impact pad for tundish, and it makes the molten steel that rebounds from shock surface flow around the longitudinal axis of this tundish is symmetrical.For for example should or each outlet be positioned on the tundish longitudinal axis, or the tundish that is symmetrically distributed around this axis of two or more outlets, this is very important.In addition, the injection of motlten metal (" casting ladle stream ") is " off-centre " usually, promptly is not positioned on the longitudinal axis of tundish.This is to move with the sliding gate of a control from the metal flow of casting ladle outflow usually because of watering ladle cover (for the pipe of motlten metal from casting ladle injection tundish), because this valve is usually only opened a part for the restriction flow rate, therefore water the usually relative tundish off-centre of ladle cover.
According to a first aspect of the present invention, a kind of impact pad for tundish made from refractory material is provided, this cushion pad comprises: one has the bottom of a shock surface, injects the motlten metal of this cushion pad when this shock surface uses towards last reception; And a wall that stretches upwards from this bottom along at least a portion periphery of this shock surface, this wall comprises the prominent eaves that stretches out above this shock surface one surrounding zone, this prominent eaves comprises and a plurality ofly stretches out farther ledge than prominent eaves remainder above shock surface.
This wall preferably extends on the whole periphery of this shock surface, thereby surrounds whole shock surface.
According to second aspect, the invention provides a kind of tundish that comprises by the described cushion pad of first aspect present invention.This tundish preferably is elongated shape (being vertical view), and its outlet is best near each vertical end, and the motlten metal that injects during use stream and cushion pad preferably roughly are positioned at vertical central authorities of tundish.This tundish is preferably between a cushion pad and the outlet and comprises the baffle plate that at least one stretches on its width.The end face of this baffle plate preferably has the central portion center of tundish longitudinal axis (promptly with respect to), and this central portion is lower than the periphery on its every limit.This helps the longitudinal axis of motlten metal conductance to tundish.
The inventor finds, uses a plurality ofly to stretch out farther ledge than the remainder of the prominent eaves of peripheral wall can make the motlten metal that knock-ons from shock surface by the central authorities of the cushion pad that roughly leads above shock surface.Even thereby the motlten metal that injects on the cushion pad shock surface is eccentric, promptly with cushion pad central authorities from a distance, the motlten metal that flows out from cushion pad is symmetry roughly still.This of the fluid that flows out from cushion pad roughly symmetry makes fluid symmetry whole tundish, thereby reduce the motlten metal what is called " dead band " of flow rate low relatively (causing new motlten metal to replenish possibility smooth and this motlten metal curing) therein, thereby the uniformity of time of staying of improving motlten metal substantially in tundish.
The shock surface of cushion pad preferably has at least two corners (for example four corners), each outstanding ledge of the top of this corner.At least one (preferably whole) corner is formed on convergence place of each straight flange roughly of shock surface.This shock surface can be polygon roughly, preferably quadrangle, particularly rectangle roughly or square.A ledge is stretched out in each corner top of polygon shock surface.As a supplement or substitute, at least one ledge (preferably two ledges or more ledges) is along most of at least length on each limit of shock surface, even its whole length extending.
In some preferred embodiment, extend in distance that the prominent eaves between the two described ledges stretches out above shock surface along its most of at least same length.Should preferably roughly stretch straight along its most of at least length by prominent eaves between two ledges.But, as a supplement or substitute, for the one or more prominent eaves that extends between two ledges, the distance that the eaves of should dashing forward stretches out above shock surface can be inequality along its most of at least length, the vertical view that for example extends in the one or more prominent eaves between two ledges can be curved, thereby for example should or each prominent eaves distance of above shock surface, stretching out in its length central authorities than far away at its two ends, also the distance that can stretch out at its two ends is than far away in the central.Merit attention, the shape of the prominent eaves between the ledge and size, and/or different and different according to the specific occasion of the shape of ledge and big I promptly are decided by the shape and the size of tundish, and/or the eccentric degree of the motlten metal that injects, or any other specific (special) requirements of user.
Cushion pad should or each ledge ultimate range of above shock surface, stretching out for the remainder of prominent eaves in the ultimate range of stretching out above the shock surface at least 110%, preferably be at least 120%, better be at least 140%, be at least 150% especially.Cushion pad should or each ledge be not more than 600% of ultimate range that the remainder of prominent eaves stretches out in the ultimate range of stretching out above the shock surface above shock surface, preferably be not more than 500%, be not more than 450% especially.
The prominent height of eaves above shock surface can be inequality along its length.Have the embodiment of at least three ledges for the present invention, the height that extends in two prominent eaves between the ledge with extend between one of these two ledges and another ledge or to extend in addition the height of the prominent eaves between two ledges different.At least a portion of prominent eaves is low than another part of this prominent eaves, and this distance of stretching out above shock surface than lower part is far away than other higher part of this prominent eaves.Thereby make and to impact motlten metal on low prominent eaves than impacting metal on the higher prominent eaves cushion pad central authorities of being led more backward from the shock surface back of rebounding, thereby help to cause metal to open (explanation of still, the effect of each side of the present invention being done should not regarded as the present invention is limited to some extent) from cushion pad stream symmetrically.
In some preferred embodiment, the surrounding zone of shock surface comprises a groove that stretches along at least a portion of shock surface central area.For shock surface the embodiment of corner is arranged, this groove is on the corner than wide at other positions.For example, the shape of this groove (in vertical view) can with the shape of the prominent eaves of this wall mirror image each other roughly.
Illustrate the present invention below in conjunction with accompanying drawing, in the accompanying drawing:

Fig. 5 illustrates the baffle plate that Fig. 4 letter is shown.
Fig. 1 illustrates the present invention's one impact pad for tundish 1, comprising: one has the bottom 3 of a shock surface 5, injects the motlten metal of this cushion pad when this shock surface uses towards last reception; And a wall 7 that stretches upwards from this bottom along the periphery of this shock surface, this wall comprises the prominent eaves 9 that stretches out above this shock surface one surrounding zone 11, this prominent eaves comprises and a plurality ofly stretches out farther ledge 13 than prominent eaves remainder above shock surface.
The vertical view of this cushion pad 1 is rectangle, and bottom 3 and shock surface 5 all are rectangle.Each ledge 3 is positioned on four corners of cushion pad.Prominent eaves 9a on the long limit of rectangle cushion pad between the ledge 13 is relatively little, and roughly is straight with identical.Prominent eaves 9b on the rectangle cushion pad minor face between the ledge 13 is big relatively, and vertical view is curved.In addition, the prominent eaves 9a of the prominent aspect ratio of eaves 9b above shock surface is low.
Shock surface surrounding zone 11 comprises a groove, and the shape of its shape and whole prominent eaves (9a, 9b, 13) roughly is mutually mirror image.
Fig. 2 is the longitudinal sectional view of Fig. 1 cushion pad.Can know and find out the dash forward width of eaves 9b and the degree of depth of groove 11.Can know also and see that shortwall 7b is vertical with shock surface 5 that prominent eaves 9b is vertical with wall 7b.But longwell 7a offset from perpendicular is them to be inclined upwardly to prominent eaves 9a from shock surface.
Fig. 3 letter illustrates from an off-centre and waters the asymmetric motlten metal stream that ladle cover injects an elongated shape tundish.In each part (a)-(c), the vertical view of tundish is shown, represent with circle that from the motlten metal of casting ladle stream this circle is in the vertical central authorities of tundish, but in horizontal off-centre, promptly than a longitudinal side wall of the more close tundish of another longitudinal side wall.This tundish also is included in a pair of baffle plate 15 (hole of flowing through for motlten metal is wherein arranged) on vertical both sides of this tundish and the outlet of representing with circle on these tundish two ends.
Arrow is represented the stream of motlten metal; The initial stream that injects the metal of tundish shown in the part (a) (according to normal operating conditions, filled with the motlten metal that flows therein in the tundish, shown in stream only represent main stream from each distance of tundish.Even), can see also that because casting ladle stream is eccentric, it is asymmetric that motlten metal flows relative tundish longitudinal axis at this commitment.In part (b), motlten metal begins to flow through baffle plate, stream asymmetric more obvious.In part (c), motlten metal has flow to outlet.Label 17 expressions so-called " dead band " in this dead band, have seldom or do not have motlten metal stream under these limits.The existence in dead band causes very big problem in the tundish, begins to solidify because of the cooling of the metal in the dead band; They also cause from the change of the metal components of tundish outflow.
Fig. 4 illustrates stream how to use cushion pad 1 change motlten metal of the present invention.Baffle plate 19 is arranged in Fig. 4 tundish equally, but than the more close outlet of Fig. 3 baffle plate.The central portion 21 lower than its both sides periphery 23 arranged on the end face of these baffle plates.
The same with Fig. 3, the casting ladle of Fig. 4 stream is still eccentric, but this moment, because the existence of cushion pad of the present invention is arranged, makes that the stream of the motlten metal that leaves cushion pad is more symmetrical.When motlten metal flow to outlet, stream is symmetry roughly, the dead band do not occur.
Fig. 5 is the front view and the profile (Fig. 3 letter illustrates this baffle plate) of baffle plate 19.This baffle plate has a bottom surface 25 and two sides 27, and its shape and big I laterally are fastened in the tundish.Its end face has a central portion 21 lower than its both sides upper periphery portion 23, thereby the guiding motlten metal flows through above along a vertical stream in the tundish from baffle plate.Therefore as the replenishing of cushion pad, it causes symmetry and/or axial motlten metal stream in tundish.Also have a plurality of perforation 29 in the baffle plate, make motlten metal, also can cross baffle plate from these orifice flows except flowing through from the baffle plate top.These holes 29 are inclined upwardly on the molten metal flow direction, thereby the stream of the metal that flows through these holes is made progress.Preferably big and reduce along baffle plate its inclination angle that makes progress for its inclination angle, lower hole.As shown in drawings, the inclination angle in minimum hole is preferably 40 °, and last hole is reduced to 30 ° and 20 ° respectively successively.Illustrated dimension is unit with the millimeter.
