Description
Technical field
The utility model relates to a kind of alloy bushing, particularly relate to a kind of can the alloy bushing of quick adjustment glass metal flow.
Background technology
It is single hole that centrifugal cotton produces bushing used, is installed on the bottom in material road, and sedimentator is sent into quantitatively uniformly by the glass metal come in the effect Shi Jiangliao road of bushing, and this is the last critical point of holding glass metal quality.The glass metal that the bushing of production centrifugal cotton flows out will enter sedimentator, and ability fibroblast after throwing away, therefore glass metal is closely related through the temperature of bushing and the working order of discharge and sedimentator, and bushing has very large restraining factors for sedimentator.When the timing of sedimentator aperture rotating speed one, flame combustion chamber is to its action condition one timing, for the glass of same viscosity, the sedimentator amount of throwing away is certain, bushing will be checked on to sending into the glass metal flow of sedimentator, only enter glass liquid measure in sedimentator enough time, could maintain sedimentator inside thickness of liquid film, be input and output material balance, fiber forming process is stablized.When entering, glass metal in sedimentator is too many, to such an extent as to when having little time to throw away, will, by sedimentator spill-over suitable for reading, be that fiber forming process interrupts.Therefore bushing have impact on the stability of fiber-forming process and the quality of the finished product greatly for the control accuracy of glass metal flow, the temperature homogeneity of bushing and stability depend primarily on the temperature of bushing, the temperature of bushing also realizes automatically controlling by electrically heated, therefore the electric heating device of bushing how is designed, make bushing temperature everywhere can realize changing fast, and only in change procedure, the temperature of each different positions of bushing can uniformity, just become and affect nozzle plate temperature stability, the accuracy and the whole glass that control glass metal flow become the glass quality of production of product process and the key point of technology stability.
Chinese patent superalloy bushing that relate to a kind of platinum plating and alloy thereof of application publication number CN 103524033 A and preparation method thereof, be coated with platinum coating and alloy coat thereof at the small opening internal surface of bushing and small opening edge suitable for reading, the shortcoming that bushing makes cost value high can be overcome.But the bushing prepared in this way makes its work-ing life greatly restricted due to the problem that there is larger thermal stresses between its coating and body material, and its control for the temperature of bushing is also difficult to reach very accurate effect, makes the quality of fibroblast and technology stability greatly be deteriorated.
The anti-glass melt adhesion method that the Chinese patent of application publication number CN 102030469 A proposes a kind of bushing hinders on bushing surface and discharge spout internal coat one deck that glass melt and bushing are surperficial, discharge spout internal surface carries out the coating that adheres to, improve the mobility of glass melt in bushing surface and discharge spout, shorten bushing and reach the time working properly, reduce costs.But due to the restriction of coated material, need to carry out the replacing of bushing coating in time of not waiting at 2 ~ 9 days, operating procedure is complicated, and particularly large to product requirement, be difficult to application when time requirement is tight especially, therefore practicality is not strong.
The bushing device bushing folder that current glass is produced is connected with base arrangement, and the size of bushing folder is also unreasonable, so just cause controlling in the process of nozzle plate temperature change in energising, although the temperature of short period of time tank-top plate reaches desired value, but the temperature at bushing sidewall and the place of leting slip a remark really cannot be raised timely, device cannot response regulation fast, and therefore Flow-rate adjustment also cannot realize fast, and for whole bushing structure design, base plate directly contacts material road, own temperature is original also higher with temperature of leting slip a remark than bushing sidewall, even if the defect therefore in this structure design and then result also in bushing sidewall and the temperature of leting slip a remark reaches required working temperature, the temperature at the base plate place of bushing device is compared to bushing sidewall and let slip a remark also higher, which results in each several part non-uniform temperature of whole device of leting slip a remark, follow-up glass metal flow control will be made like this to be difficult to accurate realization, not only bring great difficulty to actually operating, also the raising of the quality of product is made to be difficult to realize, both uneconomical, also counteracts that product popularization in the market.
Utility model content
The purpose of this utility model is intended to overcome the deficiencies in the prior art, a kind of method by alloy bushing quick adjustment glass metal flow is provided, by rational structure design, the bushing of chain receiving electrode folder is directly linked to the sidewall of small opening, make bushing in heat-processed, first bushing side wall temperatures raises, because base plate directly contacts with material road, therefore the heat that now base plate absorbs material road by self-position advantage makes the temperature of oneself respond fast, and not only can make to let slip a remark by the design of the control of bushing material and structural parameter, bushing sidewall and baseplate temp can keep harmonious, the work-ing life that bushing can keep longer can also be made, the maintenance of the corresponding bushing obtained in conjunction with our long-term practice and theoretical investigation and flow rate adjusting method, glass metal flow just can be made quick, regulate accurately.
The technical scheme adopted for realizing the purpose of this utility model is: a kind of alloy bushing, it is characterized in that described bushing is single hole bushing, two bushing folders of bushing are positioned on sidewall, wherein two bushings folder to be centrosymmetric relation about small opening medullary ray, the highest point sea line of bushing folder and small opening inlet water horizontal line place are at a distance of 50mm ~ 120mm, and small opening is the combination that important actor body and right cylinder are let slip a remark.
In described small opening structure, the bottom diameter of important actor body is 60mm ~ 120mm, and upper base diameter is 8mm ~ 15mm, and cylindrical diameter is identical with the upper base diameter of important actor body, the height of small opening is 80mm ~ 150mm, and the height that right cylinder is let slip a remark is 15mm ~ 30mm.
Described small opening wall thickness is 3mm ~ 12mm.
Described bushing folder length is 200mm ~ 300mm, and be highly 50mm ~ 110mm, thickness is 5mm ~ 20mm, wherein the horizontal structure that presss from both sides of bushing and vertical stratification transition in the arc-shaped.
Described bushing is platinum rhodium material, and wherein rhodium-containing amount is 7% ~ 10%.
The beneficial effect that the utility model has is: 1. bushing bulk temperature is very even in heat-processed, makes glass metal stability of flow, and fiber-forming process is stablized; 2. flexible adjustment, fast, rational structure design makes bushing can the change of response current fast, regulates rapidly, and the precision that can realize producing, product performance are ensured greatly and promote.
