Description
Technical field
The utility model relates to a kind of atomized spray shaping insulation crucible device, and particularly a kind of atomized spray is shaped and is incubated crucible device with Liftable type, and this device adopts the mode of threaded engagement and can realize the bushing position lifting by the adjusting screw thread.
Background technology
Reaction-injection moulding is a kind of flash set technology that produces late 1960s and grow up gradually through the development of decades.It is one and relates to the atomizing of powder metallurgy, liquid metal, multi-field new material technology of preparing such as cooling and nonequilibrium freezing fast.Reaction-injection moulding is the molten drop that liquid metal is become different size with inert gas atomizer, taken out of the range of atomization by the atomization gas that flows fast then, molten drop in flight course by a base board cutting, and on substrate, assemble and be frozen in conjunction with good near fine and close blank, it demonstrates its special advantages as a kind of semisolid near-net forming process technology.Utilize spray forming technology liquid metal can be made shapes such as pipe, rod, plate, dish, ring.
The melting of reaction-injection moulding metal is to carry out under the protection of vacuum environment or inert gas.Melt metal reaches certain degree of superheat (being generally 100～200 ℃), the insulation reasonable time, again melt metal is changed in the insulation crucible that is heated to uniform temperature, the insulation crucible is connected with catheter, so just can realize that the motlten metal liquid with certain degree of superheat enters catheter, under the effect of atomization gas, motlten metal is atomized into tiny molten drop, under the cooling effect of inert gas, motlten metal obtains bigger cooling velocity, and that atomization metal exists is solid-state, liquid state and three kinds of states of pasty state.Under the effect of atomization gas, take molten drop out of range of atomization, on substrate the deposition and solidify.
Do not need multiple working procedure when producing metal stock, can simplify technology greatly and reduce equipment investment through conventional continuous casting or powder metallurgy with the reaction-injection moulding method.In addition, because the setting time of metal is shorter in the whole process of production, so the crystal grain of reaction-injection moulding product is tiny, intensity is high, good toughness, defective are few, the feature of rapid solidification has resisted elements segregation effectively.
The effect of insulation crucible (tundish) is to accept from melting kettle in the reaction-injection moulding process and reach the molten metal bath of predetermined temperature and store and insulation.Therefore tundish need adopt mode of heating heating such as resistance or induction to guarantee molten metal temperature substantially constant before spraying.Tundish outlet at bottom place needs closely to be connected with catheter, and needs the assurance tundish to place in whole injection shape process steadily.
In the reaction-injection moulding prior art, the taper that exists tundish outlet at bottom place connects mouth and is connected not firm with catheter and is very easy to occur metal at connecting portion and ooze out, linking together with crucible point mouth and catheter retainer after the metal cooled and solidified of oozing out makes it not quick detachable, thereby the shape and size that the metal that oozes out from the junction has changed these parts attached to attaching parts have had a strong impact on the repeated use of these part parts, thereby the little tundish that causes of the contact area of tundish bottom point mouth and catheter is placed problems such as shakiness and bearing load are bigger.
Summary of the invention
The purpose of this utility model provides a kind of atomized spray to be shaped just and is incubated crucible device with Liftable type at existing weak point in the above-mentioned prior art.The easy to operate lift reaction-injection moulding tundish device of the utility model by being threaded, this tundish device can solve the connectivity problem and the tundish of catheter and tundish effectively and place unstable problem, and easy apparatus structure can be realized operation easily and address the above problem effectively.
The utility model can be realized by following technique measures:
Liftable type of the present utility model insulation crucible device comprises in the coaxial line mode and is fixedly mounted on the female graphite connecting ring of processing in the graphite tube, is installed in graphite bracing ring in the graphite connecting ring by the mode that is threaded; The hollow posts chamber of described graphite bracing ring is made up of upper and lower two chambeies of terraced structure, wherein is positioned at the external diameter of the cavity internal diameter of step top greater than the insulation crucible tundish that is placed on this cavity; The taper that is arranged in described insulation crucible tundish outlet at bottom place connects the material runner of mouth and combines closely in the mode that suit cooperates with the upper end of the catheter of the deflector that is positioned at its below, and the lower surface that described taper connects mouth combines with deflector by sealing gasket.
The beneficial effects of the utility model are as follows:
Owing to adopted in the utility model with the mode structure combining by being threaded between graphite connecting ring and the graphite bracing ring, also just realized of the adjusting of graphite bracing ring in the vertical direction position, and then the taper that realizes tundish outlet at bottom place connects mouth and is connected with the tight of catheter, play and prevent that metal liquid from connecing mouth by taper and oozing out from the coupling part of catheter, and prevent tundish from course of injection, rocking and the adverse effect that causes, and whole device also has simple in structure, easy to operate, and the preparation cost of device is low.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
The utility model is further described below with reference to (accompanying drawing):
As shown in the figure, Liftable type of the present utility model insulation crucible device comprises in the coaxial line mode and is fixedly mounted on the female graphite connecting ring 2 of processing in the graphite tube 1, is installed in graphite bracing ring 3 in the graphite connecting ring by the mode that is threaded; The hollow posts chamber of described graphite bracing ring 3 is made up of upper and lower two chambeies of terraced structure, wherein is positioned at the external diameter of the cavity internal diameter of step top greater than the insulation crucible tundish 4 that is placed on this cavity; The taper that is arranged in described insulation crucible tundish 4 outlet at bottom places connects the material runner of mouth 8 and combines closely in the mode that suit cooperates with the upper end of the catheter 5 of the deflector 6 that is positioned at its below, and the lower surface that described taper connects mouth 8 combines with deflector by asbestos seal pad 7.
Concrete assembling mode of the present utility model is as follows:
At first in holding furnace, place graphite tube, the graphite connecting ring 2 that will have internal thread is fixed on the graphite tube, again graphite support circle 3 is fixed on the graphite connecting ring 2 by threaded engagement, screw-in by screw thread with screw out the height and position that regulates graphite support circle, again middle back stall is placed on the ring platform of graphite bracing ring inner chamber, guarantee that the tundish axis overlaps with the axis of catheter, the taper of observing tundish outlet at bottom place connects whether closely being connected of mouth and catheter, closely connect if be unrealized, then regulate the upright position of graphite support circle again by threaded engagement, so just can realize easily that tundish outlet at bottom place is connected with the tight of catheter.Asbestos pad is placed in the junction that connects mouth and deflector in taper, can prevent that metal liquid from oozing out by the coupling part that shape connects mouth and catheter.In addition, owing to there is the gap of 1-3 mm between tundish and the graphite bracing ring, the position assurance tundish outlet at bottom place that can finely tune tundish is connected with catheter is coaxial, increases the compactness that cooperates.
