Abstract
The invention provides a kind of compound nozzle producing amorphous thin ribbon, it comprises two parts composition, the sheet spray seam that boron nitride nozzle body and exotic material are processed into, it is characterized in that, described sheet spray seam is that the spray laterally with the up/down perforation consistent with amorphous thin ribbon width to be processed is stitched, and described sheet spray seam inserts nozzle body and form compound nozzle together with described nozzle body.The sheet spray seam that the present invention processes by adding zirconia above boron nitride nozzle body, improves nozzle strength hardness, high temperature creep resistance is good, deformation resistance is good, thus can obtain thinner amorphous thin ribbon, improve production efficiency and product quality.
Description
Technical field
The present invention relates to a kind of metal sheet band manufacturing technology, especially a kind of amorphous alloy ribbon of producing is out of shape little nozzle.
Background technology
Amorphous alloy material has excellent combination property, as high-performance, high strength, wear-resisting, anti-corrosion, high resistivity, high magnetic conduction, low-loss etc.Because of the performance of its excellence, developed rapidly in recent years, the output filtering reactor particularly in high-frequency high-power Switching Power Supply, the main transformer in uninterrupted power source are obtained a wide range of applications.
Current amorphous thin ribbon mainly adopts single-roller rapid quenching with quenching to produce, and molten steel is cast on the chill roll of High Rotation Speed by nozzle, obtains the amorphous alloy ribbon of required width and thickness.The width of amorphous thin ribbon depends on the spray seam width of nozzle, and strip thickness depends primarily on spray seam width.Molten steel, by the uniform and stable chill roll flowed to below nozzle of nozzle, is the necessary condition ensureing that continuous spraying band normally carries out, and therefore the stuctures and properties quality of nozzle directly affects the length of continuous spraying band time.
What use in prior art is all unitary nozzle structure, with boron nitride as nozzle main material.Become the nozzle of required size and shape by the Milling Process of boron nitride blank, spray seam can determine its size according to process requirements.Due to boron nitride, to have good machinability, intensity and hardness suitable and good with molten steel wetability, substantially in current actual production uses this material to make nozzle.But this structure and material is chosen and also be there is a lot of shortcoming: boron nitride nozzle due to high temperature and effect of stress, thermal creep can occur and make spray stitch distortion, cracking, making in the middle of the amorphous thin ribbon of ejection thickening gradually in spray band process; Price is high, reuses difficulty, and cost is high; Impurity in molten steel is easily separated out at spray seam place, plug nozzle.In order to obtain thinner amorphous thin ribbon, will use narrower nozzle seam, and mouth seam is narrower, nozzle more easily blocks.
Summary of the invention
In view of this, for solving the problem, the invention provides a kind of compound nozzle producing amorphous thin ribbon, it has high temperature resistant, and deformation is little, is easy to cleaning and the feature such as reusable.
In order to achieve the above object, the invention provides a kind of compound nozzle producing amorphous thin ribbon, it comprises two parts composition, the sheet spray seam that boron nitride nozzle body and exotic material are processed into, described sheet spray seam is that the spray laterally with the up/down perforation consistent with amorphous thin ribbon width to be processed is stitched, and described sheet spray seam inserts nozzle body and form compound nozzle together with described nozzle body.
Further, described boron nitride nozzle body inner transverse is emptied, and emptying adjacent margins is convex arc streamlined, and in described nozzle body, both sides convex structure is identical.
Further, dovetail groove is had below described nozzle body for inserting described sheet spray seam.
Further, length is consistent with nozzle body length.
Further, described sheet spray seam is processed by zirconia.
The sheet spray seam that embodiment provided by the invention processes by adding zirconia above boron nitride nozzle body, improve nozzle strength hardness, high temperature creep resistance is good, deformation resistance is good, thus thinner amorphous thin ribbon can be obtained, improve production efficiency and product quality.

Fig. 2 is the structural representation of sheet spray seam in the present invention's specific embodiment, and wherein upper left side is elevation cross-sectional view, and upper right side is side cutaway view, and below is top view.
Detailed description of the invention
The present invention is directed to that the nozzle material boron nitride intensity used in prior art is low, the life-span is short, easily the problem such as blocking, design a kind of intensity for amorphous thin ribbon production high, be out of shape little, that creep-resistant property is good novel combined nozzle.In a specific embodiment, the present invention adopts fabricated structure, is nozzle body and sheet spray seam two parts by designs of nozzles.Bulk material adopts boron nitride to be raw material, easily processes, and intensity, hardness are suitable; Sheet spray seam adopts zirconia material processing and fabricating to form, and intensity hardness is high, high temperature creep resistance good, deformation resistance is good.In a specific embodiment, as shown in Figure 1, block-like nozzle body 101 material intermediate lateral emptied, emptying adjacent margins is convex arc streamlined, and in nozzle body, both sides convex structure is identical.Dovetail groove is had below nozzle body.Sheet is sprayed seam 102 and be processed into trapezium structure separately, top and bottom stand out is 2mm in a specific embodiment, length is consistent with nozzle body length, after guarantee sheet sprays seam insertion body, length is consistent, described sheet is sprayed in the dovetail groove stitching and insert described nozzle body and is combined to form combining nozzle.
Described sheet spray seam trapezium structure laterally processes the spray seam got through top and bottom, and the length of spray seam is determined by the width of produced band, and spray stitches width in a specific embodiment within the scope of 0.3-0.9mm.Need by regulating nozzle body material and sheet spray thermal coefficient of expansion stitch material in concrete process, make its mate to prevent from spraying in band process occur thermal expansion stressed cause spraying stitch strain cracking.
The sheet spray seam processed is inserted in nozzle body, carries out follow-up spray band process.In spray band process, because molten steel is comparatively strong to the thermal shock effect of spray seam, under high temperature and certain pressure, spray seam place easily deforms, thus makes the amorphous thin ribbon that finally obtains in uneven thickness.And zirconia material anti-molten steel impact by force, not yielding.After once spraying the end of tape, nozzle is taken off and leaves standstill cooling, after cooling by with after sheet spray seam take out from body, then reinsert new sheet nozzle with to be used.
Advantage of the present invention mainly comprises: adopt fabricated structure, reusable, reduces costs; With boron nitride as nozzle matrix material, hardness strength is suitable for, and machinability is good; With zirconia as spray seam main material, intensity is high, wearability good, nozzle variant is little, improve production efficiency and product quality.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement etc., all should be included within protection scope of the present invention.
