Technical field
The utility model relates to a kind of glass fiber wire drawing equipment, is specifically related to three minutes wire drawing platinum rhodium bushings of glass fibre platinum replacing stove.
Background technology
Glass fibre manufactures through high temperature melting, wire drawing, doff, the technique such as weave cotton cloth take glass sphere as raw material, the characteristics such as it has that intensity is high, chemical stability good, resistance to chemical attack, production cost are low, be commonly used for the strongthener in matrix material, electrically insulating material and heat-insulating material, the national economy every field such as circuit substrate.The filament diameter that glass sphere is pulled out is that several microns are to twenties microns, the 1/20-1/5 that is equivalent to a hairline, every bundle fiber precursor all by hundreds of even thousands of monofilament form, if obtain so meticulous glass fiber single filament, bushing plays very important effect in the glass fiber wire-drawing production process.When manufacturing glass fiber single filament, bushing must be able to bear 1200 ℃ of high temperature, so the material selection of bushing and structure design are two large technical characterictics of overriding concern.Glass fibre forming wire drawing bushing is the alloy material of platinum and rhodium at present, platinum has good erosion resistance, anti-oxidant, resistance to elevated temperatures, rhodium has high-intensity performance, the high-temperature stability of platinum is mixed with the high-strength characteristic of rhodium, be that bushing is under hot environment and the key point of generating mechanism distortion not for a long time, thereby guarantee all the time the glass fiber filaments constant diameter of pulling out.But, platinum and rhodium price are all very expensive, a bushing manufacturing cost is up to hundreds of thousands of, and the design of bushing directly determines quality and the wire drawing efficient of glass fiber wire-drawing, the distance between adjacent discharge spout, the design requirements that is width between centers is very strict, the too small wire drawing of width between centers cooling performance is poor, affects wire drawing quality and wire-drawing effect, and the excessive bushing volume that makes of width between centers becomes large, structure is compact not, has improved the manufacturing cost of bushing.In prior art, when passing through bushing by the glass metal that stays in smelting furnace, in order to strengthen its mobility, be provided with vertical heating electrode in the plug both sides of bushing glass solution is carried out second-heating, because the bushing structure is the monoblock casting part, the usage quantity of vertical heating electrode wall thickness a larger increase platinum rhodium has increased the manufacturing cost of bushing.
The utility model content
The utility model is for above-mentioned shortcoming, provide a kind of glass fibre platinum replacing stove three minutes wire drawing platinum rhodium bushings, its purpose is: the usage quantity of saving platinum rhodium, reduce the manufacturing cost of bushing, improve bushing intensity with the stiffening web bushing, increase the service life, reach that wire drawing investment is little, the purpose of good product quality, the high and low energy consumption of output.
Technical solution of the present utility model:
Three minutes wire drawing platinum rhodium bushings of glass fibre platinum replacing stove, comprise: the plug of cavity structure, be located at plug upper surface outer strongback, be located at the plug lower surface discharge spout, be located at the vertical heating electrode at plug two ends, it is characterized in that: be provided with stiffening web between the plug intracavity sidewall; Described heating electrode level is located at plug two ends, the described plug lower surface three discharge spout zones that evenly distribute.
Described discharge spout zone is provided with 198 discharge spouts.
Width between centers between described discharge spout is 5mm.
Described stiffening web is located at adjacent two region separation places of leting slip a remark, and connects the plug intracavity sidewall.
Described stiffening web height is lower than the plug upper surface.
Described plug wall thickness is at least 0.5mm.
Described stiffening web wall thickness is 1mm.
Described heating electrode is highly to be the thin slice of 1.5mm.
Described thin slice middle part is provided with the U breach.
Three minutes wire drawing platinum rhodium bushings of described glass fibre platinum replacing stove are that platinum content is 90%, and rhodium content is 10% monoblock casting structure.
The beneficial effects of the utility model:
The utility model by on bushing between adjacent discharge spout size repeatedly test, final design goes out most suitable pitch-row between discharge spout, thereby improves the cooling performance of monofilament, cooling temperature distributes more even, has shortened the cooling time of wire drawing, has improved production efficiency; Increase the distance between discharge spout, between the plug inwall, stiffening web has been set, bushing intensity is improved, strengthened the work-ing life of bushing; Heating electrode is arranged to horizontal sheet, has saved the noble metal consumption.

Embodiment
Describe the utility model in detail below in conjunction with drawings and Examples.
As shown in Figures 1 to 4: three minutes wire drawing platinum rhodium bushings of glass fibre platinum replacing stove, comprise: the plug 2 of cavity structure, be located at plug 2 upper surface outers strongback 1, be located at plug 2 lower surfaces discharge spout 3, be located at the heating electrode 4 at plug 2 two ends, it is characterized in that: be provided with stiffening web 5 between plug 2 intracavity sidewalls; Described heating electrode 4 levels are located at plug 2 two ends, the described plug 2 lower surfaces three discharge spout zones that evenly distribute.
The specific works process:
The strongback 1 that will be positioned at bushing plug 2 upper surface outers is positioned the lower surface of smelting furnace, and the bushing position is fixed.glass sphere enters smelting furnace and is heated to 1300 ℃ and carries out heating and melting one time, the glass metal of melting is first through thawing furnace bottom inflow bushing plug 2 inner chambers, because there is thermal losses in smelting furnace, heating electrode 4 needs glass metal is carried out second-heating to 1200 ℃, through three piece discharge spouts regional minute three parts of the glass metal after second-heating through the plug bottom, leak down through discharge spout 3, adjacent two region separation places of leting slip a remark arrange stiffening web 5 between plug 2 inwalls, connect plug 2 intracavity sidewalls, make glass metal evenly be divided into three parts, form three segment glass fiber filaments through discharge spout 3, after form three strands of glass fiber precursors through beaming device, realize drawing in three minutes effect.
The utility model is by repeatedly testing 3 sizes of adjacent discharge spout (width between centers) on bushing, final design goes out 3 most suitable pitch-rows of discharge spout, be increased to 5mm by 4.5mm, thereby improve the cooling performance of monofilament, cooling temperature distributes more even, shorten the cooling time of wire drawing, improved production efficiency; Increased the distance between discharge spout.Adjacent two 3 region separation places of leting slip a remark arrange stiffening web 5 between plug 2 inwalls, connect plug 3 intracavity sidewalls, reduce the thermal distortion that bushing is in the generation in hot operation for a long time, and bushing intensity is improved, and have strengthened the work-ing life of bushing.Be that the vertical structure of 4mm is arranged to highly only be the horizontal sheet of 1.5mm with the heating electrode 4 that is arranged at two ends, plug outer wall left and right by original wall thickness, under the prerequisite that does not affect heats, greatly save the noble metal consumption, thereby saved the manufacturing cost of bushing for company.
