Description
Technical field:
The utility model relates to the preparing technical field of cast aluminium alloy, especially cast aluminium alloy experiment a refining unit.
Technical background:
Cast aluminium alloy material is because of having less unit weight, good castability and good mechanical performance and physical and chemical performance, satisfied the requirement of aspects such as lightweight and energy-conserving and environment-protective well, be widely applied at present on aerospace, automobile and other conveying mechanical.But the mechanical property of existing cast aluminium alloy still can not be equal to high-strength cast steel at aspects such as intensity and toughness both at home and abroad at present, be difficult to satisfy current and from now on conveying mechanical such as automobile, aircraft to the growth requirement of aluminum alloy high-strength high-ductility mechanical property, therefore people just study cast aluminium alloy from aspects such as alloying constituent optimization, refining treatment, the rotten processing of refinement and thermal treatments, in the hope of improving its intensity and toughness.Because the cast aluminium alloy melt is the basis of post forming and processing, its cleanliness factor level, especially the content of gas and inclusion in the melt, directly have influence on high-quality and perfect the acquisition of cast aluminium alloy product and giving full play to of cast aluminium alloy proper property, therefore in the research contents the inside of cast aluminium alloy, the refining treatment of alloy melt is occupied important status.
At present, carried out a large amount of research for the refining treatment of cast aluminium alloy both at home and abroad, and successively developed air blowing body flux method and added melt method of refining such as villaumite or chloride treatment method, wherein application comparatively generally adds villaumite or chloride treatment method in the experimental study of cast aluminium alloy.Owing to adopt when adding villaumite or chloride process, mostly be with bell jar villaumite or muriate to be pressed into aluminium liquid to finish refining treatment, and the subject matter that this adding method exists has: 1. because mostly villaumite or muriate are that being pressed into the cast aluminium alloy melt by bell jar carries out refining, and mostly the bell jar that uses now is open type, therefore after villaumite or muriate are pressed into alloy melt by bell jar, villaumite or muriate and aluminium liquid full contact, reaction is very fast, cause refining time bubble short, that produce big, thereby influence refining effect; 2. because villaumite or muriate can produce irritating toxic and harmful after being pressed into alloy melt and the reaction of aluminium liquid by bell jar, and that these gases are not directly discharged is outdoor, thereby the person's that directly influences the in-house operation is healthy.
Summary of the invention:
The utility model adopts bell jar to carry out the refining treatment above shortcomings at adding villaumite or chloride process in the existing cast aluminium alloy experimental study, design and develop out a kind of problem that can solve existing method existence, and simple in structure, easy to operate, safe cast aluminium alloy experiment a refining unit.
The technical scheme that realizes the foregoing invention purpose is as follows:
A kind of cast aluminium alloy experiment a refining unit, it is used with the melting device that is combined into by resistance furnace and crucible, includes combination of splendid attire villaumite or muriatic barrel and transmission rig.Described barrel combination is adopted to be threaded by barrel body and barrel bottom and is constituted, all offer aperture on it, the barrel combination places the aluminium liquid of the crucible that is used with it, the barrel body links to each other with the transmission shaft of transmission rig by broken line/curved union lever, and transmission rig is fixed by supporting structure.
This a refining unit also is provided with the sealing cover combination, be made up of the wear ring of sealing cover and its underpart, the airway on top, have production well on the sealing cover and hold the tapered hole that union lever passes through, sealing cover places on the crucible, wear ring immerses in the aluminium liquid, and production well is connected with and leads to outdoor airway.
In addition, described transmission rig includes handle, two transmission shafts and two transmission conical gear, first transmission shaft is installed on the pillar stiffener by bearing, pillar stiffener is fixed on and together constitutes supporting structure on the back up pad, one end of first transmission shaft connects handle, and the other end is fixed with the first transmission conical gear, the second transmission conical gear and the engagement of the first transmission conical gear, and fix with second transmission shaft, second transmission shaft then with the barrel body on union lever realize being connected by bolt.
The design's principal feature is as follows:
In order to solve the not good problem of original employing bell jar refining effect, on this a refining unit, be provided with the barrel combination, it is made up of union lever, barrel body and barrel bottom, wherein all offer the aperture of certain size on barrel body and the barrel bottom, and the barrel body is connected with transmission shaft by union lever, and union lever is designed to broken line/curve shape.Above-mentioned design, 1. during refining, when villaumite or muriatic barrel body and barrel bottom being housed entering aluminium alloy melt, because aluminium liquid is to enter barrel and villaumite or muriate reaction by the aperture of offering on barrel body and the barrel bottom, make between villaumite or muriate and aluminium liquid contact unlike existing use the bell jar refining abundant, therefore react relatively slow, thereby refining time is prolonged; 2. because the gas of villaumite in barrel body and the barrel bottom or muriate and aluminium liquid reaction generation enters the passage of aluminium liquid is the aperture of offering on barrel body and the barrel bottom, and the size of aperture designs enough for a short time, therefore can make that the size that enters the bubble in the aluminium liquid is less; 3. by utilizing transmission rig can drive barrel body and the rotation of barrel bottom, and the union lever that connects barrel body and transmission shaft is designed to broken line/curve shape, barrel body and barrel bottom are rotated along the smelting pot axis in aluminium liquid, thereby make that the distribution of small bubbles in aluminium liquid of discharging is more even from barrel body and barrel bottom.Effect by these several respects can be seen, carries out refining with former employing bell jar and compares, and this a refining unit has improved add the refining effect that villaumite or muriate carry out refining treatment in the cast aluminium alloy experimental study.
Further, toxic and harmful is not directly discharged healthy the problem outdoor and person that influences the in-house operation in order to solve original employing bell jar and to carry out refining.On this a refining unit, be provided with the sealing cover combination, its underpart is provided with wear ring, top is provided with airway, because wear ring directly immerses in the aluminium liquid, therefore the toxic and harmful that produces in the time of can guaranteeing refining is not discharged into indoor, but by airway with directly discharge is outdoor, thereby the toxic and harmful influence healthy that produces when having avoided refining to the in-house operation person.
By above-mentioned design as seen, the cast aluminium alloy experiment that the utility model provides can solve the existing bell jar that adopts with a refining unit and carry out the problem that refining exists, and have advantages such as simple in structure, easy to operate, safe in utilization, the refining treatment needs of cast aluminium alloy in the time of can satisfying experiment well.
