Metal fiber wire and its producing process

Abstract

The present invention belongs to the field of metal processing technology, and is especially one kind of metal fiber wire and its production process. The metal fiber wire is made with the material comprising C 0.03-0.08 wt%, Mn 0.20-0.46 wt%, Si 0.40-0.63 wt%, Ce or La 0.02-0.10 wt%, Al 4.8-5.9 wt%, Cr 15-26 wt%, Cu 0.05-2 wt%, S 0.03-0.04 wt%, P 0.04-0.05 wt% and Fe 66-81 wt%. The making process includes the steps of: feeding material, electroplating, tubing, straightening, drawing, annealing, maintaining temperature, winding, acid pickling, washing, stoving, etc. The metal fiber wire has single fiber diameter up to 6 micron, strength higher than 16 N / sq cm, elongation of 1.40 %, and high comprehensive performance.

Description

technical field [0001] The invention belongs to the field of metal processing, in particular to a metal fiber and its manufacturing process. Background technique [0002] In the production and processing of stainless steel wire, sometimes the stainless steel wire needs to be processed very thin, and its comprehensive performance is required to be still strong and not easy to break. But existing stainless steel wire does not have such condition. A kind of invention patent called "stainless steel fiber drawn in bundles", application number: 02814697.2, discloses that its composition contains iron and the following components (expressed in wt.%): C<=0.05%, Mn≤ 5%, Si≤2%, 8%≤Ni≤12%, 15%≤Cr≤20%, Mo≤3%, Cu≤4%, N≤0.05%, S≤0.03%, and P≤0.05%. Although this kind of stainless steel fiber can be drawn very finely, after being drawn to a certain extent, the comprehensive performance of the fiber filament is not high, and it is brittle and easily broken. The existing production pro...

Problems solved by technology

Although this kind of stainless steel fiber can be drawn very thin, after being drawn to a certain extent, the overall performance of the fiber filament is not high, and it is brittle and easy to break.

The existing production process of stainless steel fiber is: tube loading, electroplating, drawing, annealing, cleaning, the stainless steel fiber processed by this process, the electroplating voltage is above 10-12V, the line speed is high, and the wire is easy to break when pulled. The pass processing rate is small, the number of annealing is large, and the chemical elements of raw materials change greatly, so the comprehensive performance is not high
