Abstract
The utility model discloses a non-blind area cooling water system of an aluminum rod continuous casting machine. The non-blind area cooling water system comprises an inner cooling water jacket installed on the inner side of a crystallization wheel of the aluminum rod continuous casting machine and an outer cooling water jacket installed on the outer side of the crystallization wheel. Multiple inner water spraying openings of a rectangular shape are uniformly formed in the shell body wall, facing the crystallization wheel, of the inner cooling water jacket, the width of each inner water spraying opening is 3-5mm, and the gap between every two adjacent inner water spraying openings is 30-50mm. The inner water spraying openings of the rectangular shape are adopted in the inner cooling water jacket, so not only is arrangement space of the water spraying openings saved, but also the arrangement of spraying angles is facilitated; parallel spraying or crossed spraying can be adopted, the amount of water supply on the two sides of an inner cavity of the crystallization wheel and chamfering positions of the crystallization wheel at the two ends of a steel belt are increased, the defect that a cooling blind area is formed due to the fact that a threaded rod is installed and the space position is occupied is overcome, the spayed water flow is high in pressure and speed, scattering does not exist, water flow beams are concentrated and powerful and can penetrate through the steam film on the surface of the crystallization wheel, and cooling effects are improved.
Description
Technical field
The utility model relates to a kind of cooling device of aluminium bar conticaster, relates in particular to a kind of non-blind area cooling water system of aluminium bar conticaster.
Background technology
Learn from casting theory: liquid metal is the cooled and solidified process, the speed of crystallization rate directly affects tissue and the moulding of ingot casting, crystallization rate is faster, ingot structure is just finer and close, but when crystallization rate is too fast, to cause thermograde to increase, thermal stress increases, and making ingot casting produce tendentiousness loose, crackle increases.Therefore, do not produce at ingot casting under the prerequisite of loose, crack defect, should improve intensity of cooling as far as possible, adopt casting speed faster, in order to obtain higher crystallization rate, ingot quality and higher production efficiency preferably.This is the theoretical foundation of cooling water system design and the principle that should follow.
After being full of high temperature aluminum liquid in the crystallizing wheel casting groove of aluminium bar conticaster, be in the moment that the crystallizing wheel outer surface of the condition of high temperature contacts with cooling water, will can vaporize immediately, on the surface of crystallizing wheel, form one deck steam blanket, this layer steam blanket hinders contacting of crystallizing wheel and cooling water, affects heat exchange effect.So when cooling water requires enough water yields are arranged, certain pressure of supply water and desirable water spray pattern also must be arranged.
In the cooling water system of traditional aluminium bar conticaster, interior cooling water spray piece is 8 arc water jackets (actual only with 6), each water jacket outside all is equipped with the interior water spout of a plurality of flat duckbill, the water spray of a plurality of interior water spouts seam area summation exceeds interior water spout branch caliber usable floor area at least 30%, the water velocity of ejection is slow, the cooling water of some section is only to flow out after the technique adjustment, spray undercapacity, be subject to again the iris action of crystallizing wheel surface steam blanket, cooling effect is very poor in addition; In addition, outer cooling jacket installed inside has a plurality of outer water spouts, and the current of inside and outside water spout ejection concentrate on crystallizing wheel centre and the steel band outside, form and spray blind area.Above-mentioned flat duckbill water spout is also very easily stopped up by foreign material, forms the water supply be not easy to perceive and educates district, even has a strong impact on ingot quality and crystallizing wheel service life.
The utility model content
The purpose of this utility model provides a kind of non-blind area cooling water system that sprays powerful aluminium bar conticaster with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The non-blind area cooling water system of aluminium bar conticaster described in the utility model comprises the interior cooling jacket of the crystallizing wheel inboard that is installed on described aluminium bar conticaster and is installed on the outer cooling jacket in the described crystallizing wheel outside, described interior cooling jacket is towards the interior water jet that evenly is provided with a plurality of rectangular shapes on the housing wall of described crystallizing wheel, the width of described interior water jet is 3-5mm, and the spacing between adjacent described interior water jet is 30-50mm.
As preferably, the width of described interior water jet is 4mm, and the spacing between adjacent described interior water jet is 40mm.
Further, described outer cooling jacket is towards the outer water jet that evenly is provided with a plurality of rectangular shapes on the housing wall of described crystallizing wheel, and the width of described outer water jet is 5-7mm, and the spacing between adjacent described outer water jet is 80-100mm.
As preferably, the width of described outer water jet is 6mm, and the spacing between adjacent described outer water jet is 90mm.
The beneficial effects of the utility model are:
Inside and outside cooling jacket of the present utility model all adopts the interior water jet of rectangular shape, not only saved water jet space has been set, and be convenient to arrange spray angle, can adopt parallel injection or crosswise jet, strengthened the output at crystallizing wheel inner chamber both sides and crystallizing wheel chamfering place, steel band two ends, overcome because the screw rod position that takes up space is installed and formed the defect of cooling blind area, and large, the speed of water flow pressure of ejection soon, not scattering, current a fluid stream concentrate, strong and powerful, can rush the steam blanket on crystallizing wheel surface, improve cooling effect.
