Description
Technical field
The utility model relates to powder metallurgy, liquid metal atomization technique, relates to the jockey of a kind of reaction-injection moulding tundish and catheter specifically.
Background technology
Reaction-injection moulding 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.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, this process is typical rapid solidification, and the crystal grain of the product of producing is tiny, intensity is high, good toughness, defective are few, and the feature of rapid solidification has resisted elements segregation effectively.In the process that metal jet is shaped, metal carries out melting under the protection of vacuum environment or inert gas, changes in the insulation crucible (tundish) after reaching the motlten metal insulation reasonable time of certain degree of superheat.Gases at high pressure atomize to continuous metal liquid stream by atomizer, make it to be broken into fine droplet, and under the chilling action of inert gas, motlten metal obtains bigger cooling velocity.Under the effect of atomization gas, take molten drop out of range of atomization, drop so on substrate cooling deposition, form metal base.
Be connected the important assurance that the atomized spray forming process is carried out between tundish and the catheter.In the reaction-injection moulding process between tundish and the catheter to be connected effect bad, can influence the stability of continuous metal liquid stream, also can cause metal liquid to ooze out, and the metal that oozes out influence normal use of the repetition of equipment or damage equipment from the junction.
Summary of the invention
Summary of the invention
The purpose of utility model provides the jockey of a kind of reaction-injection moulding tundish and catheter just at existing weak point in the above-mentioned prior art, promptly be incubated the tundish of crucible and the jockey of catheter.
The purpose of this utility model can realize by following technique measures:
The jockey of reaction-injection moulding tundish of the present utility model and catheter comprises the graphitized mesophase bag, to connect mouth by the graphite that the mode that is threaded is installed in the graphitized mesophase bag bottom thread through hole with the mode of graphitized mesophase bag coaxial line, and the material runner that described graphite connects mouth is combined closely in the mode that suit cooperates with the upper end of the catheter of the deflector that is arranged in its below, described graphite connect mouth lower end contour structures be with deflector on the mutually leakproof fit cone structure of cone-shaped groove that processes.
The upper surface that graphite described in the utility model connects mouth flushes with the inner bottom surface of graphitized mesophase bag, connects ring countertop that mouth periphery middle part is provided with connects the mouth upper surface apart from graphite height around graphite and equates with the thickness of the drain pan of graphitized mesophase bag; The contour structures that the graphite that is positioned at the Huan Tai bottom connects mouth is made up of two inverted frustums up and down, and wherein the cone angle of upper cone body is 55 ~ 75 °, and the cone angle of lower cone body is 9 ~ 15 °, and the lower surface that graphite connects mouth is the plane; The middle and upper part that described graphite connects the mouth central through hole is inverted cone inner chamber, the upper mouth of this cone inner chamber is 45 ° of chamfering structures, being positioned at inverted cone inner chamber bottom is cylindrical hole, and the length of this hole cylindrical hole is 20-30mm, and the cylindrical hole diameter is smaller or equal to the external diameter of catheter.
The beneficial effects of the utility model are as follows:
The utility model takes the mode that is threaded with tundish with connect mouth and link together, and connecing that inverted cone inner chamber in the mouth can make is that molten metal in the insulation crucible steadily successfully enters catheter; When with connect the situation that tight-lipped leakproof fit pod apertures is stopped up, can deal with problems by the method for changing-over mouth more, and be unlikely to make crucible to be scrapped.In addition, be connected with the close fit of deflector by connecing mouth, increased atomizer and tundish distance between the two, avoided atomizer directly to contact for a long time with tundish, the unlikely temperature that makes atomizer is too high and shorten its service life.In the reaction-injection moulding process, the tight connection between tundish and the catheter, guaranteed the stability of metal liquid stream to prevent that metal liquid from oozing out from the junction, be unlikely to influence that equipment is normal uses or damage equipment; Connecing under the situation that metal that mouth is being solidified stops up, can solve the problem that causes crucible to be scrapped by changing-over mouth more; In addition, that device of the present utility model also has is simple in structure, easy to operate, change easy advantage, has solved insulation crucible and catheter existing weak point when being connected in the prior art effectively.
