Present invention relates in general to the metal continuous cast production line.Particularly, the present invention relates to unit, a kind of mouth of a river, this unit, mouth of a river be fit to the mouth of a river more changing device use and be provided with and be used for preventing that unit, the said mouth of a river is loaded in the more device of changing device of the said mouth of a river with the orientation of mistake.
Background technology
Tundish container (10) is used for keeping the motlten metal such as for example molten iron or molten steel etc. (with reference to Fig. 1) of a certain amount of or full container that transmitted through ladle long nozzle (ladle shroud) (12) from ladle (11).Ladle (11) is positioned at several meters, tundish (10) top, and for the ladle long nozzle (12) of introducing the long tube in the tundish (10) from ladle (11) motlten metal is sent to tundish (10) through form.Tundish (10) is arranged on ladle (11) and Casting Equipment or mould (mould; Or title crystallizer) between (13); Motlten metal from tundish (10) is supplied to this Casting Equipment or mould (13) through filling pipe end (18); This filling pipe end (18) is positioned at tundish and is communicated with the casting mouth of a river (1) fluid, and this casting mouth of a river (1) is positioned at tundish outside and below and supplies motlten metal to be formed.
During metal casting, possibly wear and tear or mouth of a river opening (5) obstructions that possibly become in the casting mouth of a river (1), and possibly have to during change the mouth of a river (1) of casting.Be head it off; Can make water nozzle change device (100); This mouth of a river more changing device (100) comprises the opening (16) that is used to load the new pipe box mouth of a river, is used for outlet opening that the new mouth of a river is slipped into the thrust unit (31) and the guiding device (7) of casting position and is positioned at the place, opposite end of guiding device (7), and this outlet opening is used for discharging the mouth of a river of using through the mouth of a river that utilizes unit, the new mouth of a river (1) to promote to use.The loading and unloading of unit, the mouth of a river are manually accomplished by means of lazy-tongs usually and are required operating personnel to have sizable strength and precision.
Be fit to more in fact to form the unit, the mouth of a river (1) that uses of changing device by the tubular portion with central axial hole (4) with this mouth of a river; This hole is at one end along the axis opening, and at lower outlet end along axis or through horizontal window (5) opening (comparison diagram 3 (a) and Fig. 3 (b)).Said tubular portion is the top at its arrival end with plate (2), and this plate (2) is fit to closely be engaged in the corresponding mouth of a river and changes in the opening (16) of structure.This plate comprises the top slide surface (2a) of fixed head (being generally the part of the filling pipe end outlet) slip that is fit to along correspondence.The plate (2) of unit, the mouth of a river (1) comprises through hole, and the through hole of this through hole and filling pipe end is complementary, and is communicated with the vented liquid of filling pipe end when being adapted at pushing its casting position.In this application, cast tubes (4) and plate (2) combine to be called " unit, the removable mouth of a river " (1) perhaps in the time can not obscuring, abbreviate as " unit, the mouth of a river " (1) with other mouth of a river.
Under emergency situations, the filling pipe end opening must can be sealed.For this reason, can be with the plate (2) that is similar to aforesaid cast tubes (4) top but do not introduce and load opening (16) with the blind plate of through hole, and promote this blind plate and aim at filling pipe end.Some unit, the removable mouth of a river comprise plate (2), and wherein through hole is parallel to the axial dipole field of introducing the direction in the guiding device with respect to it.This permission is integrated with blind plate and unit, the removable mouth of a river; This is because at its casting position; The through hole (3) of removable mouth of a river plate (2) is communicated with filling pipe end outlet fluid; And at its detent position, therefore the filling pipe end exit face also interrupts metal bath to the cecum surface of mouth of a river plate and flows.
Since shown in the situation thrust unit (31) be suitable for promoting unit, the removable mouth of a river, so whole replacing operation is carried out along equidirectional all the time.Thus, the through hole of plate (3) must be positioned at the upstream side of the cecum part of plate top surface (2a).In fact, under emergency situations, thrust unit (31) must be suitable for unit, the removable mouth of a river is pushed to its detent position from its casting position.Though very favourable, unit, this removable mouth of a river is because following former thereby be not to be safe from danger.
The deviation post of the through hole (3) of mouth of a river plate (2) with it should offer with the orientation of the cecum part upstream side that is positioned at slidingsurface (2a) mouth of a river more this constraint of changing device (100) mean that unit, the mouth of a river is loaded onto the mouth of a river more on the changing device (100) along single orientation.In fact, if the orientation that is positioned at cecum portion downstream side with through hole (3) is loaded, then consequence possibly be catastrophic.To not form between filling pipe end (18) and the casting mouth of a river (1) that fluid is communicated with or form the fluid connection hardly; Thereby interruption casting operation; And under emergency situations, thrust unit (31,32) will further be pushed to plate the theoretical detent position of plate; But through hole (3) rather than cecum surface is aimed at the filling pipe end outlet, thereby operation of the full flow of opening metal flow path rather than interruption metal flow path.
US5188743 and WO9304805 propose the anti-collar of putting upside down to the bottom of removable mouth of a river plate to be set.This collar can be oval or is provided with a pair of radially relative dome.Yet, this scheme with plate possibly offer the mouth of a river the more directed sum of changing device be restricted to two orientations from unconfined four orientations with collar.Therefore, this scheme is not suitable for being provided with the situation of the unit, the removable mouth of a river of the long shaped plate of being with through hole and cecum surface, and this is because only allow an orientation in four orientations in this case.
US5211857 or US5174908 propose the gate safety device, and wherein gate comprises and the mouth of a river asymmetric leading edge and the trailing edge that are complementary of the asymmetric loading opening of changing device more.Yet these schemes are owing to following reason is not dealt with problems satisfactorily.At first, this type systematic can not with changing device (100) compatibility more of the already installed existing mouth of a river in the industry, and require to install more changing device of the special mouth of a river, this expression needs client's great amount of investment.Secondly, only if quite asymmetric between starboard and the leeboard lateral margin (2e), otherwise exist following dangerous: promptly, operating personnel possibly do fierce action and make plate insert more damage system also in the opening of changing device (16) of the mouth of a river by error when replace tubes more.Be noted that, at this, starboard (right side) and leeboard (left side) lateral margin (2e) be about towards treat at first to the mouth of a river more the leading edge (2c) that provides of the opening (16) of changing device (100) watch and the lateral margin that limits.

Fig. 7 illustrates according to the mouth of a river of the present invention use principle of changing device more.
The specific embodiment
The present invention has solved following problem with simple and reliable mode: prevents unit, the asymmetric removable mouth of a river is loaded into the mouth of a river more on the loading opening (16) of changing device (100) with the orientation of mistake, thus the serious consequence of avoiding this mistake to cause.Belong to such type according to unit, the removable mouth of a river of the present invention: it comprises the hollow tubular portion (4) that has through hole (3a), and an end of said tubular portion is connected with second interarea (2b) that the axis that is approximately perpendicular to this tubular portion of plate (2) extends.The through hole of tubular portion (3a) has the opening (3) with environmental communication on first interarea (2a) relative with aforementioned second interarea (2b) of plate; And the through hole of tubular portion (3a) or have the opening (with reference to (b) of Fig. 3) with environmental communication at the other end place of tubular portion (4) along the axis of pipe is perhaps located and environmental communication (with reference to (a) of Fig. 3) at the window (5) that is arranged near this end on the tube wall.Because said first interarea more will carry out tight fluid with the respective panels surface of filling pipe end during the casting position in the changing device and contact sliding into the mouth of a river, so said first surface (2a) is called " slidingsurface ".This slidingsurface is processed by refractory material and not by clad metal, in order to avoid some molten metal leakage and damage the metallic cover surface.Therefore, (2a 2b) forms: slidingsurface and plate is connected to the surface of the tubular portion (4) at the mouth of a river plate itself by two relative interareas; Two surfaces are connected through the circumference of limiting plate and the edge (2c to 2e) of thickness.Lateral margin comprises with respect to plate installs and slides into more a pair of relative leading edge (2c) and the trailing edge (2d) for the direction in the changing device of the mouth of a river.In fact this leading edge and trailing edge limit prismatic base portion, but the plate inscribe is in this prism.Under most situations, this prism is a regular prism, but this characteristic is not enforceable.Contact owing to when the trailing edge (2d) of the leading edge (2c) of second plate contact first plate to be replaced, should form quite closely between two continuous plates; So two relative leading edges and trailing edge must be complementary, and they comprise two parallel planar section under most of situation.Be parallel to as horizontal first direction (X), (2c, the lateral margin (2e) that 2d) extends extends to trailing edge from leading edge usually linearly, but can (2a has any desired contour between 2b) at two interareas perpendicular to leading edge and trailing edge usually.
In this article, if a certain shape is surrounded also " closely cooperating " in this prism inside by prism, then we can say said shape inscribe in prism, this is the definition of being accepted being generally those skilled in the art geometrically.Particularly, in all points that figure meets, their edge must be tangent.Must there be object similar with this inscribe object, bigger and that the outer figure of quilt surrounds.In the present invention, we can say that plate has the shape of inscribe in prism because lateral margin (2e) not necessarily directly and leading edge and/or trailing edge (2c 2d) meets or forms acute angle.On the contrary, in a lot of instances, the bight that makes plate smoothly possibly be favourable, or has fillet part, or the bight is cut.This helps the plate that operating personnel handle no corners, but also helps in loading opening and guiding device alignment sheets smoothly.Yet except that the bight, this plate has overall roughly prismatic geometry.
We can say that this plate is asymmetric because the opening (3) of through hole on slidingsurface (2a) with respect to first direction (X) not in plate in the heart.In fact; Under many situations; Opening (3) skew limits cecum zone so that be close to it, and this cecum zone allows through making plate slide into the cecum position interrupting flowing of metal bath from its casting position, and wherein said casting position is an opening (3) and the position of through hole (23) the fluid connection of corresponding filling pipe end (18); Said cecum position is the position of the through hole (23) of filling pipe end towards the blind area (be similar to the blind plate that is used for identical purpose, be called the cecum zone) of plate.Now; If this plate is loaded into the mouth of a river more in the loading opening of changing device by error; Then produce scenarios: when plate is pushed its casting position; Can not form between the filling pipe end of unit, the mouth of a river and the opening (3) that fluid is communicated with or limit fluid is communicated with, the result can not flow or almost flow metal bath.Under emergency situations, when must be with plate when its casting position is pushed to its cecum position, (23) be communicated with the filling pipe end perfect fluid opening (3) through the hole, thereby increase metal flow rather than stop metal flow.
In order to prevent this calamity; The present invention proposes to locate or be close to trailing edge (2d) at least one protruding handle (6) is set at trailing edge (2d); Said at least one protruding handle (6) extends transverse to said first main shaft (X1) and well beyond the circumference that limits prismatic base portion, and the crooked yield point of said at least one protruding handle (6) or maximum deflection power are between 10kgf and 2000kgf (100N and 20kN).Because exceeding the circumference that limits prismatic base portion, laterally extends said at least one protruding handle (6); Interfere with the framework that loads opening (16) so protruding handle (6) is inevitable, and will have to bending or fracture are so that allow plate to walk through said loading opening and along guiding device (7).If plate is with correct directed the loading; Then said at least one protruding handle (6) is positioned at the trailing edge (2d) of adjoining plate at the rear portion of plate; And plate can be guided through loading opening and sliding along quite a few length of lateral margin (2e) by hand closely, interferes up to the framework place of at least one protruding handle (6) arrival loading opening (16) and with the framework that loads opening (16).In said place, operating personnel can not use the hand propelled plate again, are sizable power because apply with hand under the condition that 100N is run in Casting Equipment.In this stage, start mechanical, pneumatic or hydraulic arm (31), arrive its casting position with slurcam up to plate.In this process, the crooked or fracture of said at least one protruding handle (6) is because 20kN is merely the sub-fraction (with reference to Fig. 7) of the power that the arm of force that is used for this purpose setting can apply.Preferably, said at least one protruding handle is bent without breaking plastically, falls in the mold of below so that prevent protruding handle fragment.
Just in case operating personnel plate is put the cart before the horse (that is, and make trailing edge (2d) forward and make leading edge (2c) backward) load, do not prevent the device of plate if having to be provided with, then consequence is hardly imaginable along the fault orientation loading.According to unit, the mouth of a river of the present invention can not be put the cart before the horse (that is) with trailing edge (2d) mode formerly install because said at least one protruding handle (6) will interfere with the framework that loads opening (16), lean against on the guiding device to prevent that plate from putting.Under the operating mode of Casting Equipment, said at least one protruding handle has at least the mechanical resistance of 100N (the crooked or resistance that fractures), and this is too high the crooked or fracture through loading opening for the plate of operating personnel through forcing fault orientation.Like this, even after attempting several times, operating personnel will recognize promptly that its mistake and returning face plate formerly offer the loading opening with the leading edge (2c) of plate as described above.
