Description
One, technical field:
The present invention relates to aluminium alloy casting device and method, particularly a kind of minimizing semi-continuous casting aluminium alloy flat bloom surface slag inclusion mould assembly and method.
Two, background technology:
The aluminium alloy casting process is one becomes the physical process of solid aluminium ingot by liquid aluminium cooling, crystallization, and semicontinuous casting technique is mainly adopted in the production of aluminum current alloy flat bloom.Its main production process is: aluminium liquid is poured holding furnace into after batching, after taking scum silica frost off after the thinning processing, can cast.Earlier purified treatment is carried out on the chassis before the casting, again the chassis is risen up in the crystallizer with lift, smear one deck lubricating oil toward the crystallizer inwall, in around the cooling water tank around the crystallizer, put into cooling water, drying and preheating distribution plate, floating liquid level control funnel and chute make the floating liquid level control of each mouthful of distribution plate connection funnel insert the center of crystallizer.When beginning casting, close the funnel opening earlier, open holding furnace stove eye, allow aluminium liquid flow into distribution plate through chute, treat that aluminium liquid reach a certain height in distribution plate after, decontrol the funnel opening, aluminium liquid is flow in the crystallizer, aluminium liquid promptly cools off on the chassis.When aluminium liquid decline chassis when the crystallizer intercrystalline reach a certain height, and begin to send cooling water, floating liquid level control funnel control aluminium liquid balancedly flows in the crystallizer, and keeps the aluminium liquid height in the crystallizer constant.Because the center is different with limit portion cooling condition, therefore the form that crystallization is low in the middle of forming, periphery is high, the chassis descends with regular speed, and the aluminium that solidifies withdraws from crystallizer, when aluminium ingot length reach the casting reach preseting length after, block the stove eye, take distribution plate away, treat that aluminium liquid all solidifies, and removes crystallizer, the aluminium ingot that taking-up is cast is finished casting process.
Adopt semicontinuous casting technique to carry out the aluminium alloy flat bloom casting, surperficial slag inclusion phenomenon can appear in ingot casting, surface slag inclusion problem is comparatively serious mass defect, can cause the physical property of foundry goods to reduce, produce the slab ingot crackle, also can bring out pore and little shrinkage cavity, must just can carry out the rolling process of postorder after removing surperficial slag inclusion, otherwise can have a strong impact on end product quality by cutting, milling.The reason that causes the flat bloom surface slag inclusion mainly is that the aluminium fluid wave is moving in casting process, the oxide film breakdown on aluminium liquid surface, and the scum silica frost on surface enters the surface of ingot casting.In the slab ingot casting starting stage, aluminium liquid melt flows into the chassis, does not form stable liquid level oxide-film in crystallizer as yet especially, along with aluminium liquid rolling oxide-film and scum silica frost enter the inner slag inclusion that forms of ingot casting.In order to prevent surperficial slag inclusion, generally take in the production to lay the glass wool cloth filter cloth, manually remove technological means such as the scum silica frost on aluminium liquid surface and oxide-film at the crystallizer upper surface.These technological means have reduced surperficial slag inclusion effectively, but can't effectively control the branch cloth cover and the degree of depth of surperficial slag inclusion, and the slab ingot castability can not get guaranteeing, cause that to mill the face amount in later process big, time-consuming, wastes problem such as huge and give prominence to.
