In a kind of specific embodiment scheme, the utility model provides the transfer pipe of a kind of aluminium lithium alloy casting frock, this transfer pipe comprises steel-structure tube 5, one end of steel-structure tube 5 for be communicated with vacuum standing furnace and the other end for being communicated with crystallizer, rise and support fixation.This transfer pipe also comprises match dragon pipe liner 7 and the Sai Long pipe overcoat 4 of silicon carbide material, match imperial pipe liner 7 be plugged in steel-structure tube 5 inner and and be provided with the first gap between the inwall of steel-structure tube 5, match imperial pipe overcoat 4 be sheathed on steel-structure tube 5 periphery and and be provided with the second gap between the outer wall of steel-structure tube 5, first gap and the second gap are all filled with silicon felt cotton 6, and the tube wall of steel-structure tube 5 is by cotton 6 parcels of silicon felt.Wherein, silicon felt cotton 6 plays heat-insulation and heat-preservation, simultaneously, be subject to assembly precision and match the impact of imperial tube material hardness, match one end that one end that imperial pipe overcoat 4 is positioned at aluminium liquid and the imperial pipe liner 7 of match be positioned at aluminium liquid to seal well and wrap up steel-structure tube 5, at this moment, silicon felt cotton 6 can also play the effect of sealing, prevents aluminium immersion from entering the imperial gap of managing between steel-structure tube 5 of match.
It should be noted that, because a part of heat of high temperature aluminum liquid can conduct to steel-structure tube 5, one end that steel-structure tube 5 is communicated with crystallizer is provided with sealing joint strip, easily lost efficacy after sealing joint strip is heated, so in order to ensure sealing effect, the periphery being connected to one end of crystallizer of the steel-structure tube 5 in the present embodiment scheme is welded with water jacket 1, cooling water in water jacket 1 by the heat conduction of steel-structure tube 5 to outside, thus can reduce the damage to sealing joint strip.In order to the imperial pipe overcoat 4 of match being wrapped in the periphery of steel-structure tube 5, therefore, one end of the imperial pipe overcoat 4 of match is fixedly connected on the lower end of water jacket 1 by this programme, and the other end matching imperial pipe overcoat 4 then covers the lower end of steel-structure tube 5.Lower end when " lower end " as referred to herein refers to that this transfer pipe is in use placed, as shown in Figure 1.
It should be noted that, the imperial pipe overcoat 4 of match can be fixed in several ways the lower end of water jacket 1 in this programme, such as by arranging fixed groove in the downside of water jacket 1 and utilizing pressing plate to fix, or utilize multiple buckle will the end winding support of the imperial pipe overcoat 4 of match, or the mode such as to be threaded connection be fixed.Preferably, this programme is welded with guard shield 2 in the lower end of water jacket 1, this guard shield 2 is provided with annular fixed groove, the end of matching imperial pipe overcoat 4 is provided with the annular flange flange 9 that annular fixed groove with this connects and fixes, as shown in Figure 4, this annular flange flange 9 can be stretched in annular fixed groove and to be fixed by other devices, also can by annular fixed groove being arranged to cell body and circular groove pressing plate two-part and being fixed with circular groove pressing plate.This structure can prevent silicon felt cotton 6 from dropping.Preferably, the notch of the annular fixed groove in this programme has been bolted flange 3, and annular flange flange 9 is fixed on annular fixed groove by flange 3, and arranging like this can so that dismounting and change.
It should be noted that, in order to proof strength requirement, the guard shield 2 in the present embodiment scheme is stainless steel guard shield, and stainless steel guard shield is by being fixedly welded on the lower end of water jacket 1.The guard shield of other metal materials can certainly be selected.
Lower end due to steel-structure tube 5 needs to be immersed in aluminium liquid, therefore, in order to protect steel-structure tube 5 not weather further, preferably, in this programme, one end being positioned at vacuum standing furnace of the imperial pipe overcoat 4 of match is provided with fixing snap ring 10.Concrete, this fixing snap ring 10 is exactly the flange protruded inside tube wall being arranged at the port matching imperial pipe overcoat 4, third space is provided with between this fixing snap ring 10 and port of steel-structure tube 5, and in third space, be also filled with silicon felt cotton 6, setting like this, just the tube wall of steel-structure tube 5 can be wrapped completely, further ensure the use safety of steel-structure tube 5.
For the ease of the imperial pipe liner 7 of match being fixed on the inside of steel-structure tube 5; preferably; in this programme, one end being positioned at crystallizer of the imperial pipe liner 7 of match is provided with holding flange 8; this holding flange 8 abuts with the mouth of pipe of steel-structure tube 5; as shown in Figure 3, so arrange, holding flange 8 just can be stuck in the port of the upper end of steel-structure tube 5; be convenient to place, the port of steel-structure tube 5 can also be protected further by the corrode of aluminium liquid.
The making of the transfer pipe that the utility model provides and installation process as follows:
(1), processing and fabricating this programme used unit, namely steel-structure tube 5 is together with water jacket 1, and match imperial pipe liner 7 and match imperial pipe overcoat 4, structure is as shown in Figures 2 to 4.Wherein steel-structure tube 5 adopts welding manner to fix, and matches imperial pipe liner 7 and Sai Long pipe overcoat 4 adopts carbofrax material to sinter at silicon nitride atmosphere at high temperature;
(2), to all parts of this programme assemble, as shown in Figure 1;
(3), use this programme device before, need prebake conditions be carried out;
(4), install this programme device after, need hunt leak, to guarantee the sealing of vacuum standing furnace.
The materials and structures used in this programme can be prepared under prior art conditions.
The not sticky aluminium of plug dragon pipe of silicon carbide material, intensity is high, and also resistance to corrosion necessarily simultaneously, has stronger working life in aluminium lithium alloy melt, is applicable to the casting transfer requirement of this particular aluminum alloy of aluminium lithium alloy.
Because the transfer pipe in this programme have employed match dragon pipe liner 7 and the Sai Long pipe overcoat 4 of silicon carbide material; and fill silicon felt cotton 6 in the gap between match dragon pipe and steel-structure tube 5; therefore, steel-structure tube 5 can be avoided directly to contact with aluminium liquid, can better protect steel-structure tube 5.Silicon carbide has corrosion resistance characteristic simultaneously, aluminium lithium alloy can not be polluted, in addition, silicon carbide material also has some strength, therefore, transfer pipe in this programme can either be incubated and avoid steel-structure tube 5 corrode and increase iron, has higher-strength simultaneously, greatly extends the working life of transfer pipe.Compared with prior art, this programme can be incubated, and can prevent steel pipe corrode again, and working strength is higher.
