Description

A kind of crystallizer
Technical field
The utility model relates to semicontinuous ingot casting technology field, particularly relates to the semicontinuous ingot casting technology of vertical direct water-cooling field, a kind of crystallizer using while being specially ingot casting.
Background technology
Ingot casting is exactly by the aluminum melt through being up to the standards (determining according to alloy kind) 690 DEG C~720 DEG C time, by metaideophone instrument, be poured in the crystallizer (mould) with water cooling facility, make melt fill under gravity type, cooling, be frozen into the technical process with mold cavity shape aluminium ingot base, be that melt metal passes through crystallizer continuously, realize the ingot blank production technology of solidification and crystallization moulding.In engineering, this ingot ways is called for short to DC method, i.e. direct water-cooling ingot casting method.Because being subject to the restriction of casting unit bulk, the inferior strand length of each casting all can not exceed the scope that equipment allows, and therefore this method can only be semi-continuous.
When semicontinuous ingot casting, metal bath is imported outer wall equably with in water-cooled crystallizer, rapid solidification and crystallization under the acting in conjunction of crystallizer wall and crystallizer base, and form a firmer solidified shell.When in device to be crystallized, the horizontal liquid level of metal bath reach a certain height, the haulage gear of pig moulding machine just drive base together with being set in the solidified shell on base with certain speed continuously, move down equably.The part that is frozen into strand that is separated from crystallizer is subject to directly cooling from the secondary cooling water of crystallizer lower edge immediately, and the crystallizing layer of ingot blank also advances to central area and solidification and crystallization completely thereupon continuously.Reach after given size until strand length, stop ingot casting, unload strand, pig moulding machine base is got back to home position, completes a casting time.
Though the semicontinuous ingot casting method of vertical or horizontal for realizing continuously, solidification and crystallization process by using stably, in unit interval melt bring into total amount of heat in crystallizer must with keep balance by cooling channels such as crystallizer, cooling waters to space dispersed heat, otherwise normal technical process will be destroyed.The process characteristic of semicontinuous ingot casting is: the reasonable disposition in ingot casting process between running gate system and crystallization, reduce splashing and disturbance of metal liquid, and prevent sneaking into of the harmful substance such as oxide-film and slag inclusion; Can be continuously, stably melt metal is injected to crystallizer, therefore can adopt lower pouring temperature to carry out ingot casting, this is conducive to eliminate pore and the rarefaction defect of ingot casting; Taking water as cooling medium, the solidification and crystallization of ingot casting is to complete in extremely strong crossing under cool condition, and the densification of ingot casting crystalline structure, again because crystallization remains order of crystallization, has obvious directionality, and this is conducive to remove shrinkage cavity and crack defect; The length of ingot casting is longer, can rationally cut off according to job shop technological requirement, and this can reduce the loss of crop, back-end crop.Substantially be all the semicontinuous single ingot casting of vertical direct water-cooling at present, the shortcoming of single ingot casting is as follows:
1, second-rate: because the contraction of condensation shell in crystallizer forms air gap, to produce serious Pian Xi Neoplasms on the surface of ingot casting, even occur surperficial drawing crack, bleedout phenomenon, because the instability of level control produces cold shut and dreg defect.
2, operating efficiency is lower: because of at every turn can only 6 meters of long ingot castings of ingot casting, with magnesium alloy casting rod calculate, one ton of product of ingot casting needs 22 hours altogether.
3, production cost is higher: the founding time of 22 hours, and need to make melt always in heating and keeping warm mode, casting unit is always in start running status.Manpower, electric power, material resources are all among a large amount of consumption.
4, be difficult to realize the production operation of automation: because operating, there is no enough working spaces in extremely narrow crystallizer die cavity, so automatic controlling liquid level apparatus can not be installed, can only rely on experienced workman and carry out operation.
Current domestic Ye You enterprise carries out the mode of production of semicontinuous many ingot castings, produces 2 even simultaneously, controls separately wherein 1 by 2 people simultaneously; If produce 4 simultaneously, control separately wherein 1 by 4 people simultaneously and carry out the sea of faces and operate, if increase again radical, but because not having the position that many people stand to realize.In addition,, due to for example, because of melt (magnesium and magnesium alloy) oxidizing fire very easily in air, all do not realize at present the semicontinuous industrial production system of simultaneously casting more than 4 magnesium alloy ingot of vertical direct water-cooling both at home and abroad.
Semicontinuous mold is called again crystallizer (condensate tank(trap)), every kind of crystallizer difference all forms complete ingot casting die cavity by the dummy ingot bracket matching with it because of its diameter and specification, the structure of crystallizer has not only determined the shape and size of ingot casting, also has influence on interior tissue, surface quality and the crackle situation of ingot casting.
