Abstract
The utility model discloses a small-section broad-strip spray nozzle, which comprises a spray nozzle body, wherein the spray nozzle body comprises liquid inlet cavities and spray nozzle seams which are positioned on the lower parts of a plurality of liquid inlet cavities, are connected with the liquid inlet cavities and are used for spraying liquid; reinforcing ribs are arranged between the two adjacent liquid inlet cavities; and a process hole which is parallel to the spray nozzle seams is formed below the liquid inlet cavities and the spray nozzle seams and penetrates through the lower ends of the reinforcing ribs to form accommodating cavities with the lower ends of the reinforcing ribs. According to the small-section broad-strip spray nozzle, the liquid inlet cavities are divided into a plurality of sections, and the reinforcing ribs are arranged between the two adjacent liquid inlet cavities, so that the spray nozzle can be widened to the required width on the premise of not changing the area of the cross section of the spray nozzle, the stability of the nozzle seams is high, and the stability of broad strips of the nozzle seams can be ensured in the integral production period; and the nozzle seams are continuous and smooth by the process hole formed below the spray nozzle seams.
Description
Technical field
The utility model relates to the nozzle that uses in a kind of amorphous fast quenching belt-rejecting technology, more precisely, relates generally to a kind of made bandwidth greater than the nozzle more than the 100mm.
Background technology
Adopt alloy fast quenching belt-rejecting technology to produce amorphous band; The nozzle quality is the key factor of production product quality, and its condition of work very severe requires still have stable chemical characteristic more than 1200 ℃; Keep not soaking into molten metal; Soak and have certain high temperature intensity, withstand the high speed of molten metal and wash away, and mouth seam dimensionally stable.At present, mostly the nozzle material therefor that uses in the domestic production is boron nitride (BN), and its unit price is very high.The existing market price reaches 4.15 yuan/cm
3Thereby,, design need reduce the consumption of material under guaranteeing the situation of process stabilizing during nozzle as far as possible, and the general structure that adopts of conventional spout is as shown in Figure 1; Comprise nozzle body; The nozzle mouth seam that is used for hydrojet that said body comprises admission chamber and is positioned at the admission chamber bottom and is connected with it, the structural strength at the main depending nozzle of the assurance two ends in mouth seam broadband is after spray bandwidth band increases; Guarantee the stability of mouth seam; The intensity that improves nozzle with regard to the cross-sectional area that increases nozzle solves the dimensional stability problem that mouth stitches, but since the structure of nozzle characteristics, the necessary smooth and continuous of mouth seam; Even if so increase sectional area, the dimensional stability of its mouth seam also is difficult to guarantee.
The utility model content
The utility model is in order to solve the problem that exists in the prior art; A kind of small bore broadband nozzle is provided,, can have made nozzle be widened to required width not changing under the long-pending prerequisite in nozzle throat area; Its mouth seam stability is very good, can guarantee at whole production mouth seam broadband stable in the cycle.
The technical scheme of the utility model is: small bore broadband nozzle; Comprise nozzle body; The nozzle mouth seam that is used for hydrojet that said nozzle body comprises admission chamber and is positioned at the admission chamber bottom and is connected with it, said admission chamber is a plurality of, is provided with reinforcement between adjacent two admission chambers; The fabrication hole that the below is provided with and nozzle mouth seam is parallel of said admission chamber and nozzle mouth seam, said fabrication hole pass reinforcement lower end and and reinforcement lower end formation cavity volume.
Preferably, the cross-sectional area of said fabrication hole is greater than 10 times of reinforcement lower end thickness and nozzle mouth seam width product.
Preferably, the upper end thickness of said reinforcement is 2.5～3.0mm.
Preferably, the number of said admission chamber is 3.
The beneficial effect of the utility model is; Through admission chamber is divided into multistage, be provided with reinforcement between the adjacent admission chamber, just can not change under the long-pending prerequisite in nozzle throat area; Can make nozzle be widened to required width; Make mouth seam stability very good, can guarantee that the fabrication hole that nozzle mouth seam below is provided with can make the mouth seam smooth continuously at whole production mouth seam broadband stable in the cycle.

The specific embodiment
Further specify below in conjunction with the specific embodiment of accompanying drawing the utility model.
With reference to figure 2, Fig. 3, the small bore broadband nozzle of the utility model comprises nozzle body 1, the nozzle mouth seam 3 that is used for hydrojet that said nozzle body 1 comprises admission chamber 2 and is positioned at admission chamber 2 bottoms and is connected with it, and said admission chamber 2 is a plurality of; Preferred quantity is 3.Be provided with reinforcement 5 between adjacent two admission chambers 2; The below of said admission chamber 2 and nozzle mouth seam 3 is provided with the nozzle mouth and stitches 3 parallel fabrication holes 4, said fabrication hole 4 pass reinforcement 5 lower ends and with reinforcement formation cavity volume 7.The sectional area of the utility model nozzle is suitable with the arrowband nozzle; Be a kind of can widely used broadband nozzle arrangements, through admission chamber 2 is divided into multistage, be provided with reinforcement 5 between the adjacent admission chamber 2; Do not changing under the long-pending prerequisite in nozzle throat area; Can make nozzle be widened to required width, its mouth seam stability is very good, can guarantee at whole production mouth seam broadband stable in the cycle.The nozzle that is to say the utility model be through on the nozzle original structure through segmentation and increase reinforcing rib structure, whole jet size stability is improved.After segmentation, fabrication hole 4 is set, fabrication hole 4 forms cavity volume 7 with the reinforcement lower end, cross section flow-disturbing effect can not occur to guarantee mouth seam place, has solved mouth seam smooth problem continuously.
Preferably, reinforcement upper end thickness is 2.5～3.0mm.
Preferably, the diameter of fabrication hole 4 makes its sectional area 10 times greater than reinforcement lower end thickness and mouth seam width product, guarantees that more cross section flow-disturbing effect can not appear in mouth seam place.
The speed held stationary is consistent when guaranteeing that alloy liquid is flowed through slit, and fabrication hole 4 stitches parallel with the nozzle mouth adding man-hour.
The nozzle of the utility model, after fabrication hole is opened in completion with high temperature mud 7 with fabrication hole 4 two ends shutoff, accomplish nozzle and make, as shown in Figure 4.
The utility model is through preferred embodiment having carried out detailed explanation.Yet, through to the studying carefully of preamble, to the variation of each embodiment with to increase for one of ordinary skill in the art be conspicuous.Applicant's intention is all these variations and increases the part in the scope of the utility model claim that all comprised dropping on of the utility model.
Similar numbering refers to similar element in the whole text.For the purpose of clear, has the situation that some line, layer, element, parts or characteristic are amplified in the accompanying drawings.
The term that uses among this paper is merely to be explained concrete embodiment, and it is not to be intended to the utility model is limited.Only if definition is arranged in addition, all terms that use among this paper (comprising technical term and scientific terminology) are all identical with the utility model one of ordinary skill in the art's understanding.Also must be clear and definite be, except that clear and definite definition is arranged in this article, such as in the dictionary usually the term of definition should be interpreted as and in the linguistic context of this specification and correlation technique, can have the consistent meaning, and the idealized or undue formalization that should not explain.Known function or structure are in briefly and clearly consider or repeat no more.
