Description
Technical field
The present invention relates to the fields of composite wire material manufacturing process, are related specifically to a kind of life of glass fluxing technique stainless steel wire
Production. art.
Background technique
Due to the fast development of modern information technologies, small size, high sensitivity and quickly are had increasing need in electronic field
The sensor and coil of response, and this be unable to do without high-precision, high performance insulating wrapped metal composite wire, traditional enameled wire by
It is difficult to meet the needs of high performance coil in heat resistance and insulating properties.In recent years, glass fluxing technique gold is prepared by melt spinning method
The problem of belonging to silk, then preferably resolving the thermal stability and small size of composite filament.But glass bag is prepared using melt spinning method
It covers metal fibril and needs electromagnetic field suspended metal molten bath, therefore the quality of metal bath is small (for several grams of quantitative levels), causes to melt
The stability contorting difficulty for melting spinning technique is high, and composite filament and metal core filaments dimensions are difficult to stablize, and is difficult to prepare larger straight
The glass fluxing technique wire of diameter (diameter is the 0.1mm order of magnitude).It is compound using the biggish glass fluxing technique of core filaments diameter fluctuation range
Silk prepares high performance electronic product, then can reduce the sensitivity and precision of its product.
Summary of the invention
Deficiency existing for glass fluxing technique stainless steel wire is prepared for the above melt spinning, the present invention provides a kind of glass fluxing technique
The production technology of stainless steel wire, the principle are as follows: the stainless steel wire after removal grease is immersed glass under the conditions of gas shield and melted
Chi Zhong, glass fluxing technique is behind stainless steel wire surface in melt pool, and the wire-drawing shape from composite die hole, and composite die profile is adopted
Then gone out in composite die with pyramidal structure to establish hydrodynamic lubrication condition between composite die and stainless steel wire
Glass fluxing technique stainless steel wire is made through cooling in mouth.
The technique is suitable for the production of round, flat equal section glass fluxing technique stainless steel wire, and glass fluxing technique stainless steel wire is cut
Face area is less than 2 mm2, the production of the mm composite wire material of 0.005mm≤glass bag coating thickness≤0.2, specific process parameter is,
Glass softening point is 650-900 DEG C, glass melt pool heating temperature, is 680-980 DEG C, and protective gas is nitrogen, argon gas etc., mold
Outlet drawing speed is 0.5-8 m/s, and composite die profiled outline is taper+sizing band forms, and half modular angle of conical section is
5-18 DEG C, the methods of water spray, atomized water spray can be used in mould outlet.
The invention has the following advantages that
1. the coating thickness of glass fluxing technique stainless steel wire can be guaranteed due to the effect of mold；
2. the higher precursor of precision can be used in stainless steel wire, thus can guarantee core filaments and glass fluxing technique thickness dimensionally stable and
The requirement of precision；
3. it can be by replacing the design of composite die section and the dimensions of core filaments, present invention may apply to rectangles, flat
The production of the covered composite yarn silk of the other special cross section shapes of equality；
4. can be by the design of more mold exchange, present invention is equally suited for the productions of a mould multifibres, can greatly promote production effect
Rate；
5. comparing melt spinning method, can be relatively easy to prepare the glass fluxing technique stainless steel wire being relatively large in diameter with section；
6. comparing melt spinning method, the present invention is to glass softening point and the matched requirement of stainless steel fusing point reduces namely glass kind
The range of choice of class is wider, can produce the stainless steel wire of more variety classes glass fluxing techniques.
