Description
Technical field
The utility model relates to a kind of device that is used to cast thin-wall hollow pipe.
Background technology
Current domestic, have only the filled circles ingot casting to realize that hot direct casting makes.The hollow wall pipe adopts ordinary mould casting, height owing to liquid level during casting is manually operated, very unstable, and the liquid level difference of different operators control, oxide-film is also usually destroyed, causing a large amount of oxide inclusions to take in the ingot casting goes, because more than the zone of a crystal height 80mm, form secondary remelt chance, so segregation emersion thing defective is serious, surface segregation knurl height reaches 2-3mm, the darkest 5mm that reaches, particularly big specification Φ 300* (40-50mm) ingot casting, qualified casting has only about 50%; Owing to wall book (30-50mm), liquid stream center is not easy control, so be easy to produce the cast gate crackle in addition.
" horizontal continuous casting of toothed ring tube of synchronizer method and equipment thereof " (93120535), its process is identical with the process of common existing level continuously cast billet for pipe-making, still be by alloy requirement batching → melting → casting dummy ingot, by controlling alloying component, furnace temperature, hydraulic pressure, stopping technological parameters such as degree of drawing, pipe hauling speed and startup method, thereby the alloy solution of controlling well solidifies the position in crystallizer, be used to produce the above special brass light-wall pipe of five elements.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aims to provide a kind of energy refinement ingot casting crystal grain, improves the ingot casting grain size, reduced or eliminated casting segregation emersion thing, basic stratification and the crackle of eliminating ingot casting, pore, inclusion defect are few, the hollow round ingot casting hot-top casting device that production cost is low.
The implementation of the utility model purpose is, hollow round ingot casting hot-top casting device, overcoat has the water inlet pore that links to each other with inlet water tank 19, dress condensate tank(trap) 3 in the overcoat 2, condensate tank(trap) 3 internal upper parts dress condensate tank(trap) hot top 9, bottom dress condensate tank(trap) graphite bushing 5, condensate tank(trap) apopore 20 is arranged at the bottom, fuse 12 tops cover fuse hot top 11, bottom cover fuse graphite cannula 10, form zone of a crystal between fuse graphite cannula 10 and the condensate tank(trap) graphite bushing 5,16 on fuse support is equipped with spacing gland 4 outside the condensate tank(trap) 3 on spacing gland 4, adorn the fixedly hold-doun nut 17 of fuse water inlet pipe 18 on the fuse support 16, fuse water inlet pipe 18 is by fuse support 16, the bottom margin of the hollow and fuse of fuse 12 is communicated with apopore 21, fuse plug wire 8 is arranged at the bottom of the hollow centre of fuse 12, and fuse water inlet pipe 18 has pressing plate 13 with the fuse junction surface, fuse sealing ring 15, dummy ingot 1 bottom is contained on the semicontinuous casting machine, top is stretched in the graphite bushing 5, and overcoat 2 links to each other with inlet water tank 19 by bolt 7.
During the utility model work, the high temperature aluminium alloys liquation is from the opening part inflow graphite bushing 5 of condensate tank(trap) hot top 9 and the passage between the fuse graphite cannula 10, the liquation bottom is held by dummy ingot 1, cooling water from fuse water inlet pipe 18 through the hollow cooling fuse of fuse, by fuse cooling fuse graphite cannula 10, cooling water flows out from fuse apopore 21, cooling water is entered by overcoat 2 by inlet water tank 19, cooling condensation groove 3, by condensate tank(trap) cooling condensation groove graphite bushing 5, cooling water flows out from condensate tank(trap) apopore 20, starts semicontinuous casting machine, dummy ingot 1 is along with the drive of semicontinuous casting machine, at the uniform velocity slowly move downward, the also continuous thereupon opening part from condensate tank(trap) hot top 9 of liquation flows into, through the zone of a crystal that forms between fuse graphite cannula 10 and the condensate tank(trap) graphite bushing 5, slowly crystallization forms the ingot casting pipe.
The utility model is used for reference the technology that the hot direct casting of filled circles ingot casting is made, because the graphite crystallization band is short, the liquid cave of casting process is shallow, has has greatly reduced or eliminated casting segregation emersion thing, and surface segregation emersion thing is eliminated the stratification and the crackle of ingot casting substantially less than 1mm; Because the in-mold molten surface is not stirred, eliminate artificial chance of stirring aluminium liquid, form liquid level stably, surface film oxide protects inner aluminium liquid not reoxidize all the time, reduce oxide inclusion and sneak into ingot casting, crackle and the post-job pollution again of refining of metal of effectively avoiding cast gate to produce; Because once cooling is short with the secondary cooling interval, energy refinement ingot casting crystal grain improves the ingot casting grain size, the also corresponding minimizing of pore, inclusion defect; Because graphite has lubrication, casting process does not need to lubricate, and has saved a large amount of lubricating oil, reduces production costs, and has greatly improved operating environment, reduces environmental pollution.
Adopt the utility model to improve the surface quality and the internal soundness of aluminium-alloy pipe bus, lumber recovery more than 20%, reduces process loss than raising with former conventional cast, has improved economic benefit; The grain size of ingot casting can reach 1 grade, has improved plastic deformation, helps processing.
But with various hollow tubes such as the utility model cast tube buses.
