Abstract
A process for preparing long fibres of stainless steel is a bunched drawing one, which features that after heat treatment to soften, cold treatment is performed, during which the 20-90% of cold processed quantity is completed at the temp lower than 0 deg. C. By changing temp condition and controlling processed quantity, the conversion of austenite to martensite is promoted, so improving the tension strength of stainless steel fibres.
Description
The long stapled preparation method of a kind of stainless steel relates to a kind of employing boundling hubbing and prepares the long stapled method of stainless steel.
The flexibility of existingization of stainless steel fibre pricker, synthetic fibers and goods thereof, the good electric conductivity, corrosion resistance, the heat-resisting quantity that have metal itself to have again, thereby have purposes widely.At present, stainless steel fibre is mainly used in the production of the conductive fabric (as screening clothing, heat-resisting fabric) in the textile industry, and conduction conductive plastics preparation and sound-absorbing material, electromagnetic shielding material, anti-static material, the false proof coupon of bank etc. in the plastic cement industry.The stainless steel fibre felt of making of stainless steel fibre is the state-of-the-art high efficiency filter material of the eighties, be widely used in that high-viscosity melt in petrochemical industry, chemical fibre chemical industry, the textile industry filters and aerospace industry in the oil filter.
At present, the production method of stainless steel fibre has three kinds: hubbing, cutting method and take out molten method.Cutting method and take out molten method and be mainly used in the preparation stainless steel short fiber, and mostly adopt the boundling hubbing for widely used stainless steel long fibre.This method is with in the integrated a branch of and round jacket of packing into of tens even wires up to ten thousand rod, compresses tube reducing again.Inter-adhesive in order to prevent between the work metal line, need before the boundling at metal wire surface applied separation layer, peel off overcoat when pulling to required core filament diameter and remove separation layer, obtain fibre bundle.
Austenitic stainless steel has better heat-resisting performance, decay resistance and good processing properties, being most widely used of its fiber.Application form mainly contains yarn fabric, porous material (fibrofelt) and fibre reinforced composites.Because this class alloy of austenitic stainless steel can not undergo phase transition when heat treatment, makes them not improve its mechanical performance by heat-treating methods.Can only produce distortion martensite by cold working mode and improve mechanical performance.High-nickel austenite stainless steel particularly, because nickel has strengthened austenitic stability, thereby austenite is difficult to change to Ma Shiti when carrying out cold deformation at ambient temperature.And traditional boundling hubbing normally at room temperature carries out drawing, has influenced the performance of stainless steel fibre.The diameter of Sheng Chaning is 12 microns a 316L stainless steel fibre in this way, and its stretching resistance has only about 10g, so that reduced the yield rate in its use.
The objective of the invention is to overcome the powerful low shortcoming of stainless steel fibre tension that traditional boundling hubbing production exists, a kind of a kind of new long stapled preparation method of stainless steel that can effectively improve stainless steel long fibre mechanical performance is provided.
A kind of preparation method of stainless steel fibre, its process comprises: a. electroplating copper generates separation layer at stainless steel wire surface electrical plating copper; B. boundling with the stainless steel wire after the many plating, in the copper pipe of packing into, is formed steel/copper complex; C. once-combined body processing is carried out a cold working with steel/copper complex and is drawn into once-combined line; D. secondary boundling is once-combinedly traditional thread bindingly gone in the copper pipe many, forms steel/copper secondary complex; E. secondary complex processing is carried out drawing with complex, is processed into the secondary recombination line; F. work hardening heat treatment is eliminated in heat treatment; G. separation layer and copper overcoat are removed in pickling; It is characterized in that: after eliminating work hardening heat treatment, when carrying out final cold working, it is to carry out under the temperature temperature is 0 ℃～-100 ℃ condition that 20%～90% final cold working amount is arranged.
Because at a certain temperature, be out of shape formula body difficult to understand martensite transfor mation will take place, martensite is many more, and the tension brute force is high more.Method of the present invention is exactly by to the temperature of drawing process part process and to the control of working modulus, makes deformed austenite to martensite transfor mation, to improve the tension brute force of stainless steel fibre.This method has overcome traditional boundling hubbing drawing at room temperature effectively, and the shortcoming of the stainless steel fibre mechanicalness difference of production has improved the yield rate of stainless steel fibre shop felt, is a kind of preparation method of desirable stainless steel fibre.
Below in conjunction with example method of the present invention is described further.
A kind of preparation method of stainless steel fibre, its process is: a. electroplating copper generates separation layer at stainless steel wire surface electrical plating copper; B. boundling with the stainless steel wire after the many plating, in the copper pipe of packing into, is formed steel/copper complex, requires the mutual keeping parallelism of wire rod, and is regularly arranged; C. the complex time processing pulls to steel/copper complex cold working certain size, is processed into once-combined line.In this process, can produce work hardening, plasticity is reduced, recover plasticity, so that further processing so will prepare suitable annealing process.D. the secondary boundling reinstalls many once-combined lines in the copper pipe, forms the secondary complex; E. secondary complex processing pulls to certain size with complex, is processed into secondary steel/copper composite wire; F. heat treatment, g all eliminates work hardening heat treatment in first and second complex process; After eliminating work hardening heat treatment, carry out in final cold working, to effectively control processing temperature and processing ratio at a certain temperature, 20%～90% of its processing capacity will carry out under temperature is 0 ℃～-100 ℃ condition, h. copper overcoat and separation layer are removed in pickling, obtain stainless fiber beam.
Final cold working temperature is to carry out under 0～-100 ℃ of condition, is that final working modulus is controlled at 20%～90% because austenite is transformed into martensitic process and can carries out smoothly at low temperatures, be for the hardening constituent that guarantees sufficient amount be martensitic formation.The means of acquisition low temperature of the present invention can be by adopting modes such as refrigerating chamber, freezing liquid, frozen water mixed liquor and liquid nitrogen.Adopt the method for liquid nitrogen frozen, though can reach very low temperature, but process will inevitably produce a large amount of low temperature losses, so the possible actual minimum of process is greatly about about-100 ℃, cross the effect that low temperature may produce, but consider that from the cost of practical operation adopting temperature conditions of the present invention still is both economical practicality.
