Description
Technical field
The utility model includes the casting technology field of non-ferrous metal materials industry, particularly relates to a kind of aluminium alloy narrow boards strip cast crystallizing wheel.
Background technology
Need to realize continuous casting process in the production operation of aluminium alloy narrow boards band, wherein usually use fine copper crystallizing wheel to assist and carry out crystalline forming, namely utilize the excellent heat conductivility of the crystallizing wheel of fine copper to reduce aluminum alloy melt temperature fast, reach the order ground of crystalline forming.No matter be the shape of product, crystallizing wheel generally all makes aluminium liquid fast cooling under water-cooled effect of wherein casting to similar shape, reaches the order ground of effective crystalline forming.Require during this that strengthening cooling effect is narrow boards band aluminum alloy materials continuous casting process technical conditions, simultaneously also very most important, its one side order ground of strengthening cooling effect is in order to crystal grain thinning, increases the intensity of strip; Also being to simplify subsequent technique (rolling pass) on the other hand, reducing product cost.
But the method for direct water-spraying control is all taked in many crystallizing wheel designs in the prior art, in outside, the effect of wrapped steel strip surface water-spraying control is fine, but adopt direct water spray can produce water projection situation to the crystallization wheel case of copper material, also likely enter in the aluminium liquid of casting and form bubble, have influence on the quality of crystalline product.
Find through research, open relevant technical patent and information show all there is technological deficiency:
Such as: disclosed patent content display: the crystallization wheel case that CN2374291Y proposes is that the mode utilizing aluminium liquid crystal plane to set up radiating groove behind strengthens water-cooled effect.But such crystallization wheel case only adapts to the cast shape of thicker shape, improper for thinner narrow aluminum alloy strip, and the input of equipment can be increased.
And for example: the crystallizing wheel device that CN101658903A proposes have employed the method for inside and outside directly water-spraying control, although strong cooling effect can be realized, and the measure of the cooling section elongated can increase the intensity of foundry goods, but but cannot avoid the situation that The water splash in all directions, often steam now but have impact on the interior tissue of slab.
In sum, the heteroid crystallizing wheel that continuous casting machine uses, also exists following technological deficiency: the water-spraying control 1, adopting open type, easily causes steam to enter in foundry goods and forms bubble or high hydrogeneous tissue, have impact to product quality; 2, inside and outside inhomogeneous cooling, causes crystalline structure uneven, also can affect product quality; The change of the crystallizing wheel material 3, selected, does not take into account the requirement of cooling fast, causes foundry goods coarse grain, lose the technical problems such as intensity.
In sum, how to overcome the technological deficiency of crystallizing wheel in prior art and remain those skilled in the art's technical problem urgently to be resolved hurrily.
