Abstract
The invention relates to a process for repairing refractory plate (1), having a pouring hole (3), circumscribed by a circle C of center (4), at least a portion of the edges (15, 16, 17, 18) of the plate (1) are angularly oriented so as to focus the clamping forces optimally in the throttling area and around the pouring hole.
Description
The present invention relates generally to a kind of method that is used to keep in repair the valve plate that is worn, this valve plate is used for the clamp gate valve, and this clamp gate valve is used to control the flow of motlten metal, and particularly, this valve plate prevents to cause crackle by thermal stress.
The clamp gate valve is used to control the flow of motlten metal usually in steel-making and other metallurgical processing.Such valve generally includes: bearing support; The static valve plate in top, the static valve plate in this top has the hole of aliging with the tundish or the steel ladle mouth of a river, is used to guide motlten metal stream; And choke block, this choke block has the metal guide hole equally, and this choke block can be in static valve plate slip underneath.The clamp gate valve who is used for being connected with the direct casting mould, below removable eliminator plate, also provide the lower stationary valve plate, this lower stationary valve plate has the guide of flow hole equally, and align with the hole of top static plate substantially in this guide of flow hole.The flow of motlten metal depends on the overlapping degree of the hole of removable eliminator plate slidably with respect to the hole of top static plate.Removable eliminator plate is longer than static choke block usually, so that making it can come motlten metal is carried out throttling by the leading edge and the back edge in it self hole, simultaneously can be not overlapping fully with the hole of static plate by the hole that makes it, thus motlten metal stream disconnected fully.Usually, choke block can carry out slide by hydraulic connecting rod between static plate.
Choke block and static plate are installed in respectively in bottom recessed portion and the top recessed portion, and each plate is resisted against in the recessed portion by its area supported, and by its slip or working surface and cooperating with another plate.
Such clamp gate valve's choke block and static plate are all formed by heat-resisting and corrosion resistant refractory material, for example aluminium oxide, aluminium oxide-carbon, zirconia.But, although these refractory materials have heat-resisting and corrosion resistance, their suffered serious thermal stress make they generations crackle to a certain degree the most at last.For example, in steel-making, each valve plate directly will be subjected to about 1600 ℃ temperature in the zone in guide of flow hole around it, and its outward flange only is in environment temperature simultaneously.Formed big thermal gradient produces very big thermal stress, because directly be much higher than the average level of this plate around the expansion rate in the zone in guide of flow hole at each plate.These stress cause forming the radially outer crackle in hole of slave plate.In the time can't limiting the expansion of these crackles, they can extend to the outward flange of plate always, thereby this plate is broken.
For breaking of the expansion that prevents these crackles and the valve plate that causes subsequently, several different methods has been proposed in the prior art.At first, designed improved clamping device.The purpose of these mechanisms is that the periphery around plate applies enough pressure, and like this, the crackle that disperses from the hole will can not expand to the edge of plate.A kind of such mechanism comprises the framework with screw thread operation chock, corner's engagement of this chock and plate, and the turning of this plate has been carried out truncation, the angle complementation of this angle and chock at a certain angle.Such system is introduced in document DE-C2-3522134.The framework of even now and wedge type clamping device have certain progress, but the applicant notices this design some shortcomings are arranged, and this makes it can not fully postpone potential crackle.Usually, chucking power can not evenly concentrate on the position that the maximum crackle produces, and promptly near the hole, at this place maximum thermal stress is arranged.And the applicant finds that the angle direction of the truncated corners in these plates can not be to the expansion that prevents crackle like that well of imagination in advance.These shortcomings cause crackle evenly not distribute on 360 ° of wound hole, are the longitudinal centre line along whole valve plates (static or portable plate) but lay particular stress on.Can think that crackle is the longitudinal sliding motion effect on the choke block surface of crossing static plate around the reason of the such distribution or asymmetrical distribution in hole of plate.
US patent 5626164 discloses a kind of anti-crackle valve plate; The shaped design of described plate forms therein and expands for preventing crackle.This plate has: axis; Be used to guide the hole of motlten metal, this hole is along described axis arranged; And truncated corners, be used for towards described axis with chucking power concentrate on described hole near, wherein, each described truncated corners is perpendicular to the line that extends between the point of contact in described hole, this line strides across described axis, and pass the crosspoint that is parallel to the line of restraining panel edges, the distance of this crosspoint from described edge equals half of width in described hole.
In document WO-A1-98/05451, disclose a kind of version of this scheme, wherein, determined the angle between the side of plate, thereby prolonged the service life of this plate.
Although the scheme of US patent 5626164 obviously is better than the method known in the past, the applicant still attempts to optimize the shape of this plate.
Obviously, need a kind of valve plate, the shape of this valve plate can concentrate on the zone that is easy to form crackle in the plate most with chucking power well, so that postpone the extension of all crackles to greatest extent.Ideal is that the length at turning should be enough to avoid produce undesirable local mechanical stress in this turning.
International Patent Application WO 01/41956 discloses a kind of clamp gate valve's of being used for anti-crackle valve board assembly, and it overcomes or has improved the whole above-mentioned shortcoming of prior art to small part, perhaps has at least and the equal performance of plate described in the US patent 5626164.
The document relates to a kind of clamp gate valve's of being used for refractory plate, and this refractory plate can be limited by elongated rectangular R, and this elongated rectangular R has two sides of the longitudinal direction that is parallel to this plate.The longitudinal axis of this rectangle R is defined as its longest symmetry axis, and it will overlap with the preferred sliding rail of plate.But, can know and know that the notion of this preferred sliding rail is the internal characteristics of the plate of the document, this plate can be along be not the direction of best or preferred track and sliding in the clamp gate valve.This plate is useful on the hole-tapping hole of guiding motlten metal.Under most of situation, described hole be circular, and is common, and it is that the round C of φ limits by diameter.
In order to describe, rectangle R is divided into four-quadrant (quadrant) by two vertical lines that the circle centre position at circle C intersects, and a line in these two lines extends in the middle of the parallel sides of rectangle R.All quadrants has the diagonal of intersection: diagonal D1, D3, D5, D7 make the center of circle of round C link to each other with the turning of rectangle R, and diagonal D2, D4, D6, D8 make the vertical line that the circle centre position at circle C intersects be connected with the adjacent intersection point of the side of rectangle R.
Tapping hole can be positioned at the center of plate, but under most of situation, it is axis runout longitudinally, like this, can carry out throttling in longer zone.Tapping hole also can depart from a little along the axis perpendicular to this longitudinal axis.
Plate has near the rescinded angle turning of having represented rectangle R among the edge-Tu of angled orientation-so that make chucking power concentrate on the hole and concentrate on throttling band, thereby prevents that crackle from forming therein and expand.
According to WO01/41956, at least a portion at edge is determined as follows:
(therefore the most close throttling band) departs from not 5 ° of cornerwise direction maximums of intersecting with respective corners from farthest edge of tapping hole, and
The edge of close tapping hole (therefore from throttling band farthest) departs from 5 ° of maximums in the following direction.
(i) perpendicular to cornerwise direction of intersecting with respective corners;
The (ii) direction of other each quadrant;
(iii) in direction (i) and the third side (ii) to.
The applicant thinks that really such plate shape can concentrate on chucking power two zoness of different of plate well.On the one hand, throttling band keeps compression, thereby prevents from crackle to occur in this zone, and on the other hand, the periphery of tapping hole also keeps compression, thereby prevents that crackle from extending from this tapping hole radiation.
The applicant finds that also newly-designed plate has fabulous advantage.At first, observe the crackle of much less.Secondly, even still crack, this crackle can not extend to panel edges, like this, can obviously reduce entering of air.The 3rd, when according to the plate of this european patent application when suitable clamping device is used in combination, if crackle is arranged, this crackle also only appears at acceptable zone, be that they can not occur in throttling band, and they can be not directly yet in tapping hole and the region generating between the edge recently.
An also advantage of this plate is that because crackle is considerably less, therefore, this plate can be repaired after use at an easy rate fast.Why Here it is the present invention relates to be used to keep in repair reason in the method for plate described in the WO01/41956, that used.
This plate can be with respect to its longitudinal axis symmetry, and still in a preferred embodiment, this plate is not with respect to the longitudinal axis symmetry.
Because this is asymmetric, plate can only be installed in a position and the position in the recessed portion of bottom in the recessed portion of top, therefore, under the situation that is needing this plate of recycling, when plate arrived the another location from a position, the area supported of plate became its slip or working surface.
Plate can have only four edges as defined above, and still, for fear of wedge angle, it can have more polygon edge.At this moment, the edge of Bu Chonging is can (or not) not parallel and/or perpendicular to longitudinal axis.
Should be known in that must not make this plate is polygon.On the contrary, when the clamping band that uses around this plate, this clamping band can apply local mechanical stress-this mechanical stress on the summit of being determined by adjacent edge may cause crackle.Therefore, preferably fillet is carried out at the turning.
In a preferred embodiment, only some edge satisfies above-mentioned qualification.Be more preferably, the balance at edge (balance) comprises the curve that connects described marginal portion, is more preferably the transition rounded portion that comprises described edge.
Must know that also in scope of the present invention, the meaning of " plate " also comprises component palette (fixed or movable), for example the inner nozzle plate of the mouth of a river plate of monoblock, monoblock, the tube sheet of monoblock etc.
Therefore, the present invention relates to a kind of method that is used to keep in repair the refractory plate that is worn, this refractory plate is used for the clamp gate valve, it can be defined by elongated rectangular R, this elongated rectangular R has two sides that are parallel to the prolonging direction of this plate, and tapping hole arranged, the middle part eccentric position of this tapping hole between the parallel sides of rectangle R, and by the circle C define, this rectangle R is divided into four quadrants by two vertical lines that the circle centre position at this circle C intersects, extend at a middle part between the parallel sides of rectangle R in these two lines, all quadrants has the diagonal of intersection: D1 respectively, D2 and D3, D4 and D5, D6 and D7, D8, wherein, the excision of the turning of rectangle R, and replace by beveled edge, depart from maximum 5 ° for the cornerwise direction that does not intersect with respective corners relatively away from the direction of at least a portion at the edge of tapping hole; And
The direction at the edge of close tapping hole departs from 5 ° of maximums in the following direction.
(i) perpendicular to cornerwise direction of intersecting with respective corners;
The (ii) cornerwise direction of another of corresponding quadrant;
(iii) in direction (i) and the third side (ii) to.
The method for maintaining of any appropriate can adopt.Should be known in that just because of its good anti-crackle performance these plates can be easily, keep in repair fast and efficiently.
Usually, method for maintaining comprises uses the mortar mended crack, preferably use can molten-metal-resistant mortar, phosphate mortar for example is as REFRACOL 620 PL 45.
When needing, can also before mended crack, grind by the real surface to plate.For example remove remaining steel on the surface for slave plate.Ordinary skill can use for example grinding, sand milling, water spray etc. arbitrarily.
In case repaired crackle, will remove unnecessary mortar, and make the plate drying.Drying is at least 4 hours at ambient temperature, and preferably at least 8 hours, perhaps for example in 120 ℃ stove dry 1 hour.
This plate can be cured then.This curing schedule can continue 1 hour down at 350-450 ℃.In a kind of version, solidify also and can in the process of the plate that uses this reparation, when it is subjected to than elevated operating temperature, carry out.
In specific embodiments, for example in approximately 80-120 ℃ of following preheating, like this, mortar can penetrate in the crackle plate deeply, and rapid solidification.
In another embodiment, mortar comprises curing agent, and like this, even at ambient temperature, it is rapid solidification also.
When tapping hole was impaired, it also can keep in repair.Usually, the essentially identical tubular object of the green diameter of diameter and tapping hole (for example pipe, bar or axle) inserts tapping hole.Repair, drying, final curing by the surrounding tube shaped object for mortar (identical with the mortar that is used for crackle usually).
In a kind of version, also can hole (preferably coaxial with original tapping hole, and preferably diameter than the green diameter big at least 50% of tapping hole), insert is placed the hole of new brill, and smears mortar.Preferably, this insert is made with the original material identical materials of plate at least by durability.Preferably, can make the outer wall of insert that projection or hole are arranged, like this, mortar and insert interpenetrate.Can also use the step insert, this insert be shaped as two coaxitrons that (or more) are overlapping, these pipes have identical internal diameter, but the external diameter difference.
