Abstract
The utility model provides a diversion disc which is connected with a crystallizer in a casting platform to be used for diverting molten liquid for ingot casting to each ingot casting cavity of the crystallizer. The diversion disc comprises a liquid collecting pocket used for containing the molten liquid, and multiple diversion nozzles communicated with the liquid collecting pocket and used for diverting the molten liquid in the liquid collecting pocket to the ingot casting cavities of the crystallizer, wherein the diversion nozzles are arranged on the outer surface of the liquid collecting pocket, the number of the diversion nozzles is identical with that of the ingot casting cavities of the crystallizer, each diversion nozzle comprises a base plate and two lateral plates arranged on the two sides of the base plate, and the liquid collecting pocket is in the shape of a bowl. Due to the arrangement of the liquid collecting pocket and the multiple diversion nozzles which are of specific structures and matched with the multiple ingot casting cavities in the crystallizer, the molten liquid flowing into the crystallizer can be distributed smoothly and evenly, automatic control over ingot casting is realized, and unstable factors caused by manual control are reduced.
Description
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 shunting disk using while being specially many ingot castings.
Background technology
Ingot casting is exactly by the aluminum melt through being up to the standards (determining according to alloy kind) 690 ℃～720 ℃ 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.
During 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.Until strand length, reach after given size, stop ingot casting, unload strand, pig moulding machine base is got back to home position, completes a casting time.
Semicontinuous ingot casting method can be divided into two kinds of vertical or horizontals by the strand method of operation.The semicontinuous ingot casting of vertical direct water-cooling, is succeeded in developing by Frenchman for 1933.So far become the production method that copper, aluminium, magnesium, zinc and alloy ingot blank thereof extensively adopt.
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 by cooling channels such as crystallizer, cooling waters, to space dispersed heat, keep balance, 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, reduced splashing and disturbance of metal liquid, and prevented sneaking into of the harmful substances 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; Take water as cooling medium, and the solidification and crystallization of ingot casting is to complete in extremely strong crossing under cool condition, and ingot casting crystalline structure is fine and close, 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; Better than working condition with pig iron ingot casting method.
At present, the semicontinuous ingot casting of vertical direct water-cooling is single ingot casting, and the shortcoming of the semicontinuous single ingot casting of vertical direct water-cooling 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
the magnesium alloy casting rod of 90mm is calculated, and 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 in the crystallizer die cavity extremely narrow, there is no enough working spaces, 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, by 2 people, controls separately wherein 1 simultaneously; If produce 4 simultaneously, 1 that by 4 people, is controlled wherein is separately carried out sea of faces's operation simultaneously, if increase radical, but because not having the position that many people stand to realize again.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 systems of simultaneously casting 4 above magnesium alloy ingots of vertical direct water-cooling both at home and abroad.
If realize many castings simultaneously, the melt flowing in crystallizer must be shunted.The melt how steadily uniform distribution flows in crystallizer becomes the problem that those skilled in the art pay close attention to.
