Abstract
Side wall for a continuous casting device between movable walls of metallic products, in particular of thin products, device comprising two cooled movable walls which are opposite and driven simultaneously in the same direction 3, 4 and two of the said side walls 6 delimiting the casting space, characterised in that the side wall comprises in the vicinity of the movable walls , two inserts 7, 8 of a material having good thermal conductibility, which adjoin the edge 11 of the movable walls, present a face 73, 83 directed towards the casting space, extend so as to be in the proximity of the neck 5 between the movable walls, and delimit between them a zone consisting of a covering of thermally insulating material 9, the surface 91 of which is plane or concave. The invention applies particularly to continuous casting between cylinders of thin steel products.
Description
The present invention relates between removable wall, continuous casting thin metal goods between roller particularly, the equipment of continuous casting steel product particularly particularly limits in the casting space near the transverse edge of described removable wall, the transverse wall of so-called " sidewall " (side walls).
Various types of, all have a problem that how transverse end of the casting space between removable wall is sealed at the equipment that carries out continuous casting between removable wall.
Another problem is how to prevent that the cast metal is bonded on this transverse wall, because thisly cling the danger that the edge that makes the continuous casting goods breaks.
Also have a problem is how to prevent to form the wedge shaped layer of solidifying because of partly contacting with removable wall more than the neck, so-called neck is meant the narrowest passing through a little between the removable wall.
For addressing these problems, proposed to adopt heat insulation transverse wall, thereby so that stoped solidifying of producing when contacting to stop the described wedge layer that solidifies of formation with transverse wall.A kind of device of the type was just described among the applicant's the french patent application No.8705234.
Mentioned a kind of transverse wall that has back angle among file US3038219 and the EP212423, promptly the surface of transverse wall is towards the mutual deflection symmetrically of neck.Specifically, this structure can allow metallic article in preparation process when it during near neck pro rata to horizontal expansion, and this expansion is because to taking place in process of setting in other words conj.or perhaps that the roll extrusion effect of solidifying wedge of before having solidified causes.
Yet this structure can not be prevented the seepage of the liquid metal between transverse wall and the removable wall, and in this zone, the control of liquid towards metal freezing is very inadequate.In fact, even this transverse wall has enough heat-blocking actions thereby can stop solidifying of the cast metal that is in contact with it, the seepage of liquid metal can take place still in the zone of transverse wall and removable wall interfaces.And the material of making this high heat-blocking action transverse wall has only very little mechanical strength usually.Therefore, under the rubbing action of metal and roller end, they have worn and torn soon, and the seepage of having aggravated liquid metal like this.
Conversely, if the transverse wall thermal insulation is less, then contacted with it cast metal will be solidified.But, because this solidifying is unmanageable, so even transverse wall has back angle, the problem, the irregular problem of problem of clinging or metallic article edge that form wedge shaped layer still exist.
The objective of the invention is to overcome above-mentioned deficiency, impel edge to cool off, but do not make the metal premature solidification that contacts with transverse wall whole width, especially its big side of continuous casting goods.
According to this purpose, theme of the present invention is to propose a kind of transverse wall that is used for the equipment of continuous casting thin metal goods between removable wall, this equipment comprises two removable walls that face one another the cooling of face, and these two removable walls are driven on same one side simultaneously and limit a casting space with two described static transverse walls.
According to the present invention, this transverse wall is characterised in that it comprises that one is close to the baffle plate (closure plate) of removable wall end face, with two liners of making by the high heat transfer material (insert), two liners stretch into the casting space between the removable wall and are adjacent to the edge of described removable wall, they have the face towards casting space, two liners extend near and the zone that qualification one covering of being made by heat-barrier material constitutes between two liners of neck between the described removable wall, and this obducent surface can be plane or concave surface.
By device of the present invention, with the cooling the contacted frozen metal of removable wall epidermis extend in liner (insert) on the face of casting space.Formed continuous epidermis has covered the position that removable wall and liner join mutually, thereby has stoped the seepage of liquid metal at this position.And the zone in the liner of transverse wall does not form the epidermis of contact with it, because this zone has high heat-proof quality.
According to special construction of the present invention, all have back angle reliefsngle towards the surface of casting space with by liner substantially towards surface and heat insulation obducent surface that the face of casting space constitutes by transverse wall.Because this structure has been arranged, the back angle of transverse wall just can allow the edge of continuous casting goods extending transversely.Meanwhile, the edge with the contacted epidermis of liner little by little leans against on the removable wall under the effect of liquid metal static pressure.
On the other hand, liner its gradient reduces to the lower end gradually from the upper end of liner with respect to being orthogonal to vertically also tilting to some extent of removable wall towards described of casting space, at lower end, described face towards casting space is substantially perpendicular to removable wall.
In this case, just can further strengthen the effect that the edge that solidifies epidermis is laid gradually, these gradually broadening and thicken solidify epidermis near the epidermis that forms thickness basically identical in two whole width ranges the neck area at the continuous casting goods.
Specifically, this special structure can make the power that vertically acts on the roller wall reduce to minimum.
In fact, if solidifying from the height of liquid metal of epidermis edge forms tongue-like part perpendicular to the roller wall, then when approaching neck, these tongue-like parts will thicken, and liquid metal static pressure just not enough so that they be against equably on the wall of cooling of roller, like this, will produce irregular solidifying, and can the bigger power of generation near two tongue-like parts meet and will be by the neck of " roll extrusion ".
In addition, if these tongue-like parts are not against on the wall of cooling rightly, just no longer can guarantee the sealing between roller and the transverse wall, liquid metal just has the danger that seepage takes place between the transverse wall of tongue-like part and vicinity.And adopt above-mentioned special construction just can remove this danger effectively.
Another theme of the present invention provides a kind of between removable wall, the equipment of continuous casting thin metal goods between the roller particularly, and this equipment is characterised in that it has the transverse wall that has a kind of said structure.
The present invention also has a theme to provide a kind of employing the said equipment continuous casting production thin metal goods, the method of the less steel band of thickness particularly, in the method, liquid metal is sent into casting space and liquid level is remained under liner and the heat insulation obducent upper end, two removable walls are pressed simultaneously with driving on the one hand, the result, solidify with the contacted liquid metal of the removable wall of described cooling, thus, formed and solidified epidermis, the edge of epidermis extends to liner on the face of casting space, these epidermises are along with the mobile and proportional ground broadening of removable wall and thicken, till meeting near the neck area between the described removable wall, can take out the thin metal goods that solidify downwards continuously up to them at last.
In order to understand the present invention and other features and advantages of the present invention better, the most preferred embodiment that continuous casting is produced that carries out of the present invention will be described below between roller.
Accompanying drawing for reference is Fig. 1-Figure 10, wherein:
Fig. 1 is the part schematic diagram that carries out the equipment of continuous casting between roller, there is shown the structure of transverse wall of the present invention,
Fig. 2 is the cutaway view of II among Fig. 1-II face;

Fig. 1 mainly is for content of the present invention being described, deliberately not coming picture to be convenient to understand theme of the present invention and purpose according to the relative scale size of each part among the figure to the schematic diagram among Fig. 6.
Fig. 1 has represented to carry out an end of the equipment of continuous casting between roller, this equipment comprises two rollers 1 and 2, and second roller wherein only schematically represented with the end line 21 of its wall.
The axis of these two rollers is parallel to each other and be positioned at same horizontal plane P place, two rollers are driven in rotation according to the rightabout of arrow 3 and 4, with the position of the corresponding neck 5 of the height of the plane P of passing roller axis, the distance that two rollers are separated is corresponding to the thickness of continuous casting goods.
Adopt a kind of known method that liquid metal is sent into casting space, this casting space is limited with the transverse wall that is positioned at the roller edge and contact with the sealing of described edge by the wall of that part of roller that is positioned at the neck top.Obviously, because transverse wall is static and wall roller is movable, so, for violent friction that prevents both and the wearing and tearing that cause thus, must between leave the function gap of minimum.Because sealing can not be absolute, exists the danger of liquid metal generation seepage, therefore, the danger that reduces the liquid metal seepage is one of purpose of the present invention.
In fact, as this specification mention at the beginning, if transverse wall is not solidified by the liquid metal that the material with enough heat-insulating properties constitutes to guarantee to contact with it, then and the contacted metal epidermis that solidifies of the sidewall of the cooling of roller arrive till the position, boundary between transverse wall and the roller, therefore, at this position, the danger of seepage is very high.
Instructing imagination of the present invention is exactly will extend on directly adjacent with the roller that part of transverse wall by making the metal epidermis that solidifies especially, to guarantee the sealing of liquid towards metal, and meanwhile, make the edge of these metal epidermises be easier to moulding and will prevent solidify again with the contacted metal of transverse wall.Therefore, the frozen metal epidermis that covers position, boundary between roller and the transverse wall has constituted the sealed wall that prevents seepage.
Fig. 1 shows one by vertical dull and stereotyped 61 transverse walls that constitute or " sidewall " 6, and this flat board 61 is with respect to the end of roller 1 and 2, that is leaves a function gap with respect to the end face of roller 1 and 2 cylinderical surfaces.Dull and stereotyped 61 have two liners of being made by highly heat-conductive material 7 and 8.The thin slice that each liner is all very little with thickness, its thickness preferably is approximately half of continuous casting products thickness, and they are according to the curvature bending of roller, and the inside from flat board 61 towards casting space is outstanding, so that match with the edge of cylindrical wall.The height place that the lower end 71,81 of two liners of same transverse wall is preferably in a little more than neck 5 joins.Two liners 72,82 reduce to its lower end 71,81 from its upper end gradually from dull and stereotyped 61 outstanding width.Liner all is skewed with respect to roller at this bus of highly locating towards the face 73,83 of casting space on any height, its gradient is increased towards the lower end gradually by the upper end of liner, and at lower end, gradient is approximately 90 °.In other words, the face 73,83 of each liner is warp surface, 72,82 places, upper end at liner, it for example is 135 ° pure angle that the horizontal bus of face 73,83 and the corresponding bus of adjacent roller have separately constituted an angle respectively, this angle reduces gradually towards the below, equals 90 ° substantially up to the lower end at liner.
The covering 9 that is positioned at zone between same " sidewall " two liners and is by a plate or a fireclay insulating refractory constitutes, this covering preferably is plane towards the surface 91 of casting space and is skewed with respect to vertical direction, thereby the back angle of having mentioned above constituting, this back angle can clearly be seen that in Fig. 2, so just can constitute a continuous surface with the face 73,83 of two liners, and in their boundary line place smooth transition.Cure process is preferably passed through on the surface of refractory material 9, in case the cast metal makes it cross quick-wearing.
Certainly, should be appreciated that in continuous casting production process, the liquid level of liquid metal must be controlled under the upper limit of liner and refractory material.
As shown in Figure 2, the lower end of liner can form the part of suddenly takeing in 62 with respect to dull and stereotyped 61, is similar to the described situation of aforesaid file EP212423, and the edge of being convenient to cast product like this is extending transversely in the neck area freedom.Yet,, preferably can guarantee face 73,83 and the refractory surface 91 and the continuity that is right after the transverse wall portion 63 under it of liner as what hereinafter will describe in detail.
The face 73,83 of two liners also can be and the face of surface 91 coplanes of refractory material 9 that like this, the making of described liner is just simplified.And can also guarantee the continuity of solidifying epidermis in the interface zone between roller and the liner.Yet from below with reference to Fig. 3 to the explanation of Fig. 6 as can be seen, this structure is little to the help of the moulding of described epidermis and desirable variation.
Fig. 3-Fig. 6 has represented in continuous casting production process the corresponding horizontal cutaway view of this continuous casting installation for casting on as shown in Figure 2 each height.
Fig. 3 has schematically illustrated a cutaway view that is positioned near the height III place of liquid metal height N.Motlten metal 10 contact with the wall of the cooling of roller 1 and 2 and solidify and on each roller, formed thickness less solidify epidermis 101,102.These epidermises extend tongue-like part 103,104 parts that contact with liner 7,8 and solidify, and liner the 7, the 8th can heat conduction, and they contact because of the wall that approaches the roller cooling and with the metal of flat board 61 and are cooled.But can not solidify when in contrast, the cast metal contacts with fireclay insulating refractory 9.As seen from the figure, the epidermis that solidifies has been guaranteed the sealing at the position 105,106 between roller and the liner from upper height.
Fig. 4 be the wall of the roller that is rotated when epidermis 101,102 when delivering to middle part height IV at this cutaway view of highly locating.Meanwhile, tongue-like part 103,104 is accompanied by this and moves and slide on the face 73,83 of liner.
Epidermis 101 ', 102 ' and tongue-like part 103 ', 104 ' thickness along with the continuation cooling of cast metal and increase.The width of the face 73,83 of each liner reduces because of the increase of this face with respect to the gradient of roller wall.Meanwhile, because shrinking back of transverse wall solidify the contact width increase of epidermis and roller, and under the effect of motlten metal static pressure, tongue-like part abuts in correspondingly on the roller wall.Because there is back angle on the surface 91 of refractory material 9, so the width of casting space also is increased.
At the lower end of liner height V place (Fig. 5), the thickness of epidermis 101 ", 102 " further increases.Abut on the wall of roller at two tongue-like parts that form on two liners respectively and meet at 108 places simultaneously.
In neck area (height VI, Fig. 6), two parts epidermis contacts fully and has been molded into the goods 109 with required shape of cross section, and because the last increase of width of casting space, so under the roll extrusion effect, oriented leeway extending transversely, the edge of continuous casting goods, up to it with till wall portion 63 contacts.
So far fully can be clear, equipment of the present invention:
Can guarantee the sealing of casting space;
Allow the continuous casting goods extending transversely;
Epidermis, the especially formation and the variation at its edge (tongue-like part) are solidified in control, and have prevention to form on transverse wall to solidify epidermis.
Fig. 7 shows the most preferred embodiment of " sidewall " of the present invention to Figure 10.
In this embodiment, dull and stereotyped 61 are dressed up with set screws by several parts, like this can fixed-bearing 7,8.It comprises a flat support plate 64, two support plate 65,66 usefulness screws 111 are fixed thereon and locate by centring pin 112, the surface of this two support plate will place the position relative with the end of roller, and its edge 67,68 has the curvature identical with roller and be just in time tangent with roller in their extension.
The thickness of liner is constant (for example 2 millimeters).Its width changes from top to bottom, and at upper end, they are from the surface outstanding several millimeters (for example 5 to 10 millimeters) of support plate, and at lower end, overhang obviously reduces (for example 1 to 2 millimeter).These data here are explanation as an example only, and they are to decide on the concrete overall dimensions of equipment.These data and liner and refractory material obducent to be approximately 1 ° to 3 ° back angle corresponding.The shape of the face 73,83 of liner 7,8 as previously mentioned, so they are with respect to the uniform variation that is changed to of the gradient of roller wall.Therefore, the upper end of liner is one roughly to be the oblique angle cross section of 45 degree, and this angle is extended downwards and increased along with liner, and to lower end, the cross section of liner becomes angular cross section always.
A metal intermediate plate 69, its both sides are inserted between two liners according to the curvature moulding of liner, thereby two liners are posted by on the edge 67,68 of bending of support plate 65,66.These intermediate plate 69 usefulness screws 113 are anchored on the gripper shoe 64.
The thickness of intermediate plate 69 so just can place a fireclay insulating refractory 9 between intermediate plate 69 and two liners less than support plate 65,66, and the face 91 towards casting space of this refractory material 9 flushes with the face 73,83 of liner.This fireclay insulating refractory can be a prefabricated board that engages with intermediate plate 69, also can be with above for example spraying technology is sprayed on material.
The lower end of liner, intermediate plate 69 and insulating refractory covering 9 all is positioned at the sustained height a little more than neck.Separate slightly in this lower end of highly locating two liners,, thereby prevent this tip embrittlement so that leave certain width at " tip " of fireclay insulating refractory.
Below this height (corresponding with the height V of Fig. 2), transverse wall extends by the guiding boots 120 that a usefulness screw 114 is fastened on the gripper shoe 64.In the corresponding grooves 122,123 that insert on the support plate 65,66 at the rear portion 121 of these guiding boots.The front portion 124 of guiding boots is processed to have the end face 125,126 with the corresponding curvature of curvature at the edge 67,68 of support plate 65,66.This guiding boot upper has a back crack district (reliefzone) 127 as the extension of refractory cover 9 to the face of cast product above neck, and below neck (the height place of plane P), have one with surperficial coplanar vertical plane district 128 of support plate 65,66.
These guiding boots 120 are by the material with excellent abrasive resistance, and for example cast iron is made.
Particularly with the relevant back crack district 127 of part 62 that takes in shown in Figure 2, the advantage of the structure of above-mentioned guiding boots 120 is that it can guarantee transverse wall and continuous casting goods Continuous Contact, thereby the lower end that can prevent liner and refractory cover is crossed quick-wearing or broken.
Certainly, the present invention is not limited to the above-mentioned embodiment of character for example.To each component part of transverse wall and assembly method thereof variation on the multiple technologies can be arranged.
For example, liner can be made without single metal material, and can be with resembling boron nitride class, BN and SiALON or Si
3N
4Or the composite of AlN or SiC and so on is made.
The surface 91 of refractory cover also can be concave surface rather than plane.
Liner also can further insert between the roller, and in this way, the guiding boots also can insert between the roller equally, thereby protrude in support plate.
Also can pass through to adopt a kind of local cooling device, near liner (insert), local cooling support plate and/or gripper shoe and guiding boots, or directly liner is cooled off the formation of solidifying the tongue-like part of epidermis with help.
