The specific embodiment
As depicted in figs. 1 and 2, the mouth of a river according to the present invention is integral water gap, wherein, single pipe consists of filling pipe end part and the lower mouth of a river part (4a, 4b) of pouring spout (4), and through hole extends to the second portion place (4b) at the mouth of a river under the formation or near outlet (2b) from the outlet (2a) of the end of the first (4a) that consists of filling pipe end.External flanges (5) separates filling pipe end part and the lower mouth of a river part (4a, 4b) at the mouth of a river, this flange extends and comprises first guide surface (5b) of export-oriented (2b) perpendicular to tubular axis, and second clamping area (5a) on opposite, the second clamping area (5a) is separated by flange thickness and the first guide surface.Flange is used for the mouth of a river is fixed on its casting position along the whole circle distribution of pipe.
Have a plurality of functions according to the mouth of a river of the present invention flange (5).The first, flange is used for by utilizing clamping tool (104) to apply clamping force and with the receiving plane of nozzle clip on the framework of the cut-out casting gate device (100) that matches to second clamping area (5a) of flange.This guarantees that the mouth of a river accurately aims at framework and slip parting tool (101).Clamping force is preferably and is substantially perpendicular to flange clamping area (5a).As shown in Figure 5, clamping tool (104) is preferably on two relative sides that are distributed in flange at least.In addition, clamping tool also can be arranged on flange four faces facing each other.In Fig. 2 (a), Fig. 3 (a) and preferred embodiment shown in Figure 5, flange clamping area (5a) is comprised of two different oblique clamping areas, and flange (5) thickness outwards reduces gradually from pipe.The inclination angle is preferably horizontal by 30-60 °, more preferably about 45 ° ± 3 °.Clamping tool (104) applies the clamping force that is substantially perpendicular to oblique clamping area (5a), and this helps to make the mouth of a river with respect to framework receiving plane (referring to Fig. 5) placed in the middle.
The second, flange the first guide surface (5b) has the function of guiding parting tool when parting tool passes pipe.This function realizes by the first surface (5b) as export-oriented (2b) of guide surface, so first surface (5b) is the plane, and with the pipe approximate vertical.
The 3rd, guide surface (5b) is guaranteed the remainder at the mouth of a river and the close contact between the parting tool, and the through hole of seal watering opening part (4a) also stops flowing of metal bath fully thus.In fact, parting tool (101) comprises and is suitable for the cutting plate that slides along the plane vertical with mouth of a river axle roughly.Described cutting plate comprises sharp blade (101c), blade has enough hardness with the path of cutting cutting plate by pipe, make cutting plate form main sealing surface (101b), sealing surface is face-to-face state with the through hole of the mouth of a river upstream portion that stays put.Parting tool in cutting-off process direct route and the close contact acting in conjunction between cutting plate (101) and flange (5) guide surface (5b), guarantee in case of emergency to interrupt reliably at any time flowing of metal bath fully by driving parting tool (101).In order to ensure the sealing surface (101b) of parting tool (101) and guide surface (5b) close contact of mouth of a river flange (5), the framework that cuts off the casting gate device is provided with compaction tool (105), its elasticity is pressed on the parting tool (101), with realize between parting tool sealing surface (101b) and the flange guide surface (5b) closely with contacting of sealing.As shown in Figure 5, compaction tool is directed in and has a certain degree, be preferably at 45 ° with horizontal plane about, to apply the power that is approximately perpendicular to two relative bevelled edge to parting tool (101).Because parting tool (101) must slide through pouring spout along a direction, sealing tool must be to two edge application of forces that are parallel to the parting tool track.Can not only guarantee good contact between sealing surface (101b) and the guide surface (5b) can also make parting tool (101) in whole cutting-off process, keep the middle position to two of parting tool (101) the relative edge application of forces with about 45 ° angle.
The 4th, the geometry of flange circumference helps to control the mouth of a river with respect to the angular orientation of its central axis.For the mouth of a river with the outlet (as shown in Figure 2) that is positioned at tubular portion wall side, the mouth of a river, this point is particularly important.In this case, the directed particular importance of outlet, this orientation can be by guarantee that the flange geometry only is complementary with the framework receiving plane on desired orientation and are controlled.The preferred geometries of flange circumference is that its symmetry axis quantity is identical with the permission number of positions of side outlet window.Particularly, if the flange circumference is quadrangle, then trapezoidally guarantee single permission position, rectangle allows the mouth of a river that two different North-south positions are arranged, and square has allowed four equivalent positions (two of North-south, two of Dong-Xi).In a word, if flange must possess the effect of auxiliary mouth of a river orientation, then the flange circumference must not be circle.
Fig. 2 is two embodiments according to the mouth of a river of the present invention.The something in common of two kinds of embodiments is that the length of the second time mouth of a river part in the mouth of a river (4b) is considerably beyond the first filling pipe end part (4a).The sidewall of two kinds of embodiments in contiguous mouth of a river part (4b) end all has four exit windows (2b).This lower mouth of a river is called invades the mouth of a river (shroud nozzle), is applicable to little square billet (billet) or bloom (bloom) continuous casting.This can prevent metal bath (" the intrusion mouth of a river ") by side outlet window (2b) from the mouth of a river ingress of air out the time.Under many circumstances, two relative side windows only are set.The orientation of each exit window is extremely important to the quality of foundry goods, can be directed by above-mentioned flange geometry control.
On the other hand, Fig. 3 is two embodiments at the casting mouth of a river, and this mouth of a river is generally short than invading the mouth of a river, and its opening (2b) is opened on the tubular axis.This casting mouth of a river is applicable to the little square billet of die casting and bloom.Embodiment shown in Fig. 2 (a) and 3 (a) and difference between the corresponding embodiment shown in Fig. 2 (b) and 3 (b) are relative with guide surface (5b) in the first two embodiment and tilt with respect to guide surface towards second clamping area (5a) of import (2a), and in latter two embodiment, the second clamping area (5a) is parallel with the first guide surface (5b).The geometry of the second clamping area (5a) depends on the design of the mouth of a river with the instrument that cuts off casting gate device (100) clamping.It is placed in the middle in device that the second clamping area (5a) that tilts more is conducive to the mouth of a river.Yet the something in common of these two kinds of embodiments is:
A) according to the present invention, guide surface (5b) is the plane, and roughly vertical with described mouth of a river tubular axis; And
B) middle water containing opening aligns with the framework that cuts off the casting gate device by clamping tool, and aligns with the tundish bottom unlike traditional design.This innovation concept so that the mouth of a river and parting tool systematically accurately aim at.
The same refractory material that all adopts of other parts at flange and the mouth of a river is with the high temperature of tolerance metal bath.Because flange (5) is subject to cutting off the clamping stress that the clamping tool (104) of casting gate device applies, flange at least in part the clad metal shell to strengthen.But guide surface (5b) can not clad metal shell (22), because in case drive parting tool, described guide surface must form closely heat-resisting the contact with cutting plate (101).If guide surface (5b) clad metal shell (22), then guide surface itself can be melted because of the contacting metal melt, thereby causes leakage.
In order to help to form the section of " neat ", the tubular portion at the mouth of a river according to the present invention must be provided with reduction groove (6) at flange guide surface (5b) and second time mouth of a river part (4b) junction.The reduction groove is preferably the whole circle distribution along pipe, shown in Fig. 2 (c) and 3 (c).The reduction groove both can be along the part of outside, the mouth of a river or the continuous groove that distributes of whole girth roughly, also can be intermittent (being interrupted) groove.
As shown in Figure 4, comprise the framework that limits the upper, middle and lower according to cut-out casting gate device of the present invention (100), clamping tool (104) can be with nozzle clip according to the present invention in framework, the first filling pipe end part (4a) at the mouth of a river is extended above framework upper, flange (5) is fixed on frame mid portion by clamping tool (104), and second time mouth of a river part at the mouth of a river extended below the framework bottom.Device (100) also comprises parting tool (101).Parting tool (101) comprises the cutting plate with first and second relative main surfaces (101a, 101b), and cutting plate thickness separates these two main surfaces, and parting tool (101) also comprises sharp cutting blade (101c).Cutting plate is slidingly mounted on frame mid portion, make the first main sealing surface (101b) parallel with the flange guide surface (5b) at the mouth of a river and with it the contact, thereby make a side of cutting blade (101c) second time mouth of a river part of contact (4b), shown in Fig. 4 (a).If there is emergency, cutting plate can be driven from the position that described permission metal bath is proceeded to cast, being parallel to flange guide surface (5b) walks to the opposite side of second time mouth of a river part (5b), thereby cut off second time mouth of a river part (4b) at the mouth of a river, shown in Fig. 4 (b).Apply thrust by compaction tool (105) to the cutting plate of parting tool, sealing contacts to help to form closely between the top seal face (101b) of parting tool and flange guide surface.Thrust is preferably the relative both sides of the cutting plate that puts on parting tool, more preferably apply (although also can adopt other angles) with about 45 ° ± 3 ° angle, even thereby in parting tool (101) motion process, cutting plate also can be placed in the middle continuously with respect to the mouth of a river.As shown in Figure 5, in the present embodiment, the necessary chamfering of two opposite side of parting tool cutting plate, the orientation of its angle and compaction tool is complementary.Obviously, compaction tool (105) should be positioned at the parting tool Shi Buhui that is activated becomes the current obstacle of parting tool.
The cutting plate material is generally cast steel, also can adopt refractory material, because in use, the main upper sealing surface (101b) of cutting plate seals the mouth of a river through hole that upstream extends from flange (5), and therefore contacts with metal bath.On the other hand, blade can be strengthened with hardened materials such as carbide.The guide surface of mouth of a river flange (5b) is to guarantee blade (101c) along the guide surface of expectation route operation, is again the sealing surface that cooperates with sealing surface (101b) coupling that seamlessly follows closely in blade (101c) downstream.Flange guide surface (5b) and sealing surface (101b) all need adopt the refractory material (that is, not clad metal shell) of exposure, in order to avoid the fusing of metal leakage thing coats the partial shell on this surface.
Fig. 6 is the embodiment that is applicable to the parting tool (101) of cut-out casting gate device of the present invention.From shown in embodiment can find out, hole (102) surrounds outside, the mouth of a river (4b) (referring to the position, the mouth of a river of dotted line sign), the downstream edge in hole consists of blade (101c), and blade (101c) in case of emergency passes through and the cut-out pipe.The sealing plate (101b) that follows the downstream part of described blade (101c) closely be set to and blade (101c) between gapless, to seal the spacious hole that cuts off pipe.This geometry has farthest reduced the metal bath leakage rate in the cutting-off process.
Cutting plate activates under the driving effect of mechanical arm, pneumatic arm or hydraulic arm (102), the casting position (referring to Fig. 4 (a)) that parting tool (101) can be flowed uninterruptedly from metal bath is pushed to sealing station, wherein, blade (101c) is driven to have moved apart from d, move to the opposite side of pouring spout, cut off the pipe parts (4b) (referring to Fig. 4 (b)) that extend in flange guide surface downstream.Main upper sealing surface (101b) and flange guide surface (5b) close contact of cutting plate interrupt flowing of metal bath by the spacious hole (2) that seals flange horizontal plane place thus.
