Abstract
The invention relates to a novel process for producing micron-grade stainless steel fibers, comprising the following steps of: utilizing a vertical covering welding method: drawing a covered mild-carbon steel strip into steel covered stainless steel fine wires, and separating wires; and utilizing the vertical covering welding method: bending one side of a copper strip into a cylindrical shape and covering hundreds of the stainless steel fine wires into the copper strip by the other side; bundling and drawing; carrying out heat treatment; and carrying out acid bath separation. The method disclosed by the invention is high in production efficiency, the whole production process is energy-saving and environment-friendly, and the performance of the produced stainless steel fibers is reliable.
Description
Technical field
The present invention relates to a kind of boundling drawing and produce the new technology of stainless steel fibre.
Background technology
Develop rapidly along with material science; Stainless steel fibre is with its special performances; Not only be widely used in all kinds of high density filter screens, silk screen field; And be applied in the accurate industry such as all kinds of weaving face fabrics, semiconductor, electronics, optics, stainless steel fibre has been applied to the extreme field of high-tech simultaneously, and this quality requirements to stainless steel fibre is increasingly high; Granular, softnessization more.But the stretcher of existing stainless steel fibre and market demands have very big gap, and its subject matter is filament in drawing process, are prone to fracture of wire, have influenced the quality of product; Aspect production technology, the subject matter of drawing stainless steel fibre is at present: poling is difficult, and production efficiency is low, and first step all is that steel wire is penetrated in copper pipe or the steel pipe in the now common boundling drawing production method, and pipe can not be oversize; Removal is wrapped in matrix material and the encapsulating material on the stainless steel fibre, and it is prone to produce industrial waste gas, contaminated environment.
Summary of the invention
For overcoming above-mentioned defective, the present invention improves a kind of new technology of producing the micron order stainless steel fibre, this method production efficiency height and whole process of production energy-conserving and environment-protective, the stainless steel fibre dependable performance of production.
In order to achieve the above object, the present invention realizes through technical scheme once:
A kind of new technology of producing the micron order stainless steel fibre comprises the steps:
(a) with vertical clad welded method: coat mild-carbon steel strip and be drawn into the ladle stainless steel filament;
(b) separated time: the filament that is divided into some certain-lengths;
(c) with vertical clad welded method: bend to cylindrical shape with copper strips and with the one of which limit, Yi Bian will become hundred stainless steel filament to be coated in the copper strips;
(d) boundling drawing;
(e) heat treatment;
(f) acid bath separates: in sealed shell of tank, utilize nitric acid to remove to be coated on the peripheral copper strips of hundred stainless steel filament, and be converted into nitric acid through the nitrogen dioxide that the hydrogen peroxide of in jar, sending atomizing forth produces nitric acid and copper reaction and return and continue utilization in the tank body.
The present invention compared with prior art; Have obvious improvement and substantive distinguishing features: the present invention has changed original production technology; Abandoned the poling step of original inefficiency, improved efficient and do not received the long restriction of poling, can produce long as requested apart from fiber; Acid bath isolation technics of the present invention has overcome the reaction of nitric acid and copper and has produced the nitrogen dioxide problem of environment pollution caused, and can reduce the consumption of raw material nitric acid, has saved producing cost greatly, and has reached the purpose that reduces discharging consumption reduction.
Figure of description
Fig. 1 is a structural representation of the present invention.
The specific embodiment
In order to deepen to understanding of the present invention, will combine accompanying drawing and embodiment to describe in further detail below to originally doing, this embodiment only is used to explain the present invention, protection scope of the present invention is not constituted to limit.
Embodiment 1: the present invention relates to a kind of new technology of producing the micron order stainless steel fibre with the boundling drawing, comprise the steps:
(a) with vertical clad welded method: coat mild-carbon steel strip and be drawn into the ladle stainless steel filament;
(b) separated time: the filament that is divided into some certain-lengths;
(c) with vertical clad welded method: bend to cylindrical shape with copper strips and with the one of which limit, Yi Bian will become hundred stainless steel filament to be coated in the copper strips;
(d) boundling drawing;
(e) heat treatment;
(f) acid bath separates, and in sealed shell of tank, utilizes nitric acid to remove to be coated on the peripheral copper strips of hundred stainless steel filament, and is converted into nitric acid through the nitrogen dioxide that the hydrogen peroxide of in jar, sending atomizing forth produces nitric acid and copper reaction and returns and continue utilization in the tank body.
As shown in Figure 1: it comprises stainless steel tank body 1, drive nozzle 3 and H for the special equipment in the acid bath separating step
2O
2Container 2, the upper end of tank body 1 are equipped with pressure detecting table 6 and temperature detection table 7, and drive nozzle 3 is built in the top of tank body 1, H
2O
2 Container 2 is placed on tank body 1 on one side, and a conduit 4 that has noncorrosive pump 5 is with drive nozzle 3 and H in the tank body 1
2O
2Container 2 conductings connect, and noncorrosive pump is used to extract H
2O
2Solution in the container.Pass through noncorrosive pump in the use with H
2O
2Solution is squeezed in the stainless steel tank body, since the existence of drive nozzle, H
2O
2Solution to around send forth, fully react with the nitrogen dioxide gas that produce to produce: H2O2+2H2O=2HNO3, continue to utilize in getting back to behind the reacted nitric acid jar.
