Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Fig. 1: cross-sectional schematic of the present utility model;
Fig. 2: schematic top plan view of the present utility model.
The specific embodiment
As Fig. 1, shown in Fig. 2, the nearly end form ingot casting of aluminium alloy Semi-continuous casting crystallizer, comprise crystallizer body 2 and heat preservation hot top 1, heat preservation hot top 1 is placed on crystallizer body 2, between heat preservation hot top 1 and crystallizer body 2, be provided with oil gas and distribute ring 4, oil gas distributes on ring 4 along being circumferentially evenly distributed with respectively injecting hole 6 and oil filler point 5, crystallizer body 2 comprises cooling water cavity and the water spraying structure being connected with water cavity, water spraying structure is non-wide formula water crack structure 8, crystallizer body comprises cooling water cavity and the water spraying structure being connected with water cavity, water spraying structure is non-wide formula water crack structure, make to distribute along the circumferential cooling water flow non-equivalent of crystallizer, in 0 L/min * mm ~ 0.95 L/min * mm range, in cooling water cavity, be provided with water knockout drum 7.
By non-wide formula water crack structure 8, making cooling water flow be non-equivalent along ingot casting periphery distributes, according to ingot casting appearance and size, by adjust crystallizer water seam width make cooling water flow line density along ingot casting periphery in 0 L/min * mm ~ 0.95 L/min * mm range.Crystallizer dependence water seam or hole for water spraying mode realize cooling water flow line density and change along ingot casting periphery.
Crystallizer adopts heat preservation hot top and cooling wall to solidify ingot casting, for improving the surface quality of nearly end form ingot casting, controls segregation layer thickness, be designed with oil gas and distribute ring 4, play the effect that improves ingot surface quality, wherein, the width of oil filler point 5 is 0～2.5mm, be highly 0～1.6mm, the spacing of adjacent two oil filler points is 1～5mm, and the width of injecting hole 6 is 0～3.9mm, is highly 0～2.8mm, the spacing of adjacent two injecting holes is 1～6mm, the oilhole that oil filler point is designed to body to get through.In casting process, compressed air and lubricating oil enter oil gas by injecting hole 6 and oil filler point 5 respectively and distribute ring 4, wherein compressed air and melt pressure form dynamic equilibrium, under heat preservation hot top, edge promotes metal bath, make it form meniscus, reduce the static pressure of metal solution to crystallizer liner.Lubricating oil forms skim lubricating oil film at crystallizer inwall after oil outlet, plays continuous lubricating crystallizer inner surface, reduces the effect of frictional force between ingot casting surface and crystallizer.In casting process, nearly end form crystallizer adopts oil gas to distribute ring continuously for after compressed air and lubricating oil, and ingot surface quality significantly improves.Also can in casting process, can select to lead to lubricating oil and compressed air according to ingot surface quality requirement, or continuous oil injecting lubricating only obstructed compressed air, or obstructed lubricating oil and compressed air simultaneously simultaneously.
Heat preservation hot top 1 is arranged in crystallizer body 2 tops, works to keep melt temperature, increases fluidity of molten, improves metal feeding capacity.Crystallizer body 2 is formed through machined by aluminum alloy plate materials or the red copper sheet material of rolling deformation, and in casting process, crystallizer body 2 liners directly contact aluminum melt, and the once cooling of nearly end form ingot casting is provided.For guaranteeing that the cooling water of crystallizer inside is evenly distributed, avoid because of crystallizer chamber body out-of-shape and the asymmetric cooling water flow variation causing of water inlet position, in crystallizer indoor design, have water knockout drum 7, its effect is the object that keeps height of water level, uniform distribution water cavity internal cooling discharge in cavity.
The nearly end form crystallizer internal cavity shape of cause is specification not, so metal bath is inconsistent at the freezing rate of each position of inner chamber, and some position is even subject to shape difference affect and cause freezing rate difference excessive.For guaranteeing carrying out smoothly of casting process, adopt non-wide formula water seam, along ingot casting periphery, rely on water seam width adjusting cooling water flow value, realize cooling water flow and be non-equivalent distribution along ingot casting periphery.According to the variation of cooling water flow, control intensity of cooling and the solidification shrinkage trend of nearly end form ingot casting integral body, and then realize smooth casting.
Adopt crystallizer not only can retrain liquid metal, make it be frozen into needed ingot casting shape, and can guarantee ingot casting smooth surface, uniform quality, meet the dimensional requirement of ingot casting subsequent thermal moulding.
First according to shape of product, consider thermal deformation requirement, the ingot casting appearance and size that design outline is close, designs nearly end form mold shape and thermal insulating material shape after the solidification shrinkage amount of consideration ingot casting.Thermal insulating material is arranged in crystallizer body top, plays and keeps molten metal temperature and above crystallizer, maintain certain metal liquid height, improves the mobility of melt and the effect of stamp.
According to the nearly end form ingot casting geomery of design, by adjusting the circumferential cooling water sphere of action of crystallizer and intensity, adjust the whole intensity of cooling of ingot casting, and then control the solidification shrinkage amount of nearly end form ingot casting diverse location, realize the even contraction distortion of whole nearly end form ingot casting.Because of nearly end form ingot casting change in shape, the intensity of cooling of each position of ingot casting differs greatly, different with flat ingot casting crystallizer from traditional round ingot casting, nearly end form crystallizer cooling water flow must circumferentially be adjusted along crystallizer according to the change of cast ingot position, otherwise will cause some position of ingot casting to produce excess shrinkage, increase the frictional force of ingot casting surface and crystallizer inwall, cause ingot casting cracking or surperficial tear mark, cannot realize smooth moulding.Therefore, this crystallizer adopts non-wide formula water to seam meter and adjusts the intensity of cooling value of ingot casting diverse location, and then adjusts the solidification shrinkage amount of nearly end form ingot casting integral body.
In addition, for improving the surface quality of ingot casting, improve forging process lumber recovery, design oil gas distributes ring.In use according to technological requirement, set the scope of oil and gas content addition.If ingot surface quality is required strictly, can select simultaneously continuously for lubricating oil and compressed air.Crystallizer supplies after lubricating oil gas medium continuously, ingot casting smooth surface, stable, and segregation layer thickness can be controlled at and be less than 0.9mm.
The nearly end form 6 ' ' ' line aluminium alloy ingot blank that adopts the utility model crystallizer to prepare, ingot casting moulding situation is stable, and smooth surface, without drawing the defects such as trace, breach.
It is to be understood that: the above is only preferred embodiment of the present utility model; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
