Problems solved by technology

In the whole production process, copper is a non-consumable product. In the early stage of metal fiber production, copper needs to be purchased, and the dissolved copper needs to be processed after production. This process requires a lot of manpower and material resources, which not only increases production costs, but also May pollute the environment

Embodiment Construction

[0019] A metal fiber production process of the present invention mainly includes the steps of arrangement in a mould, casting, turning, wire drawing and stripping:

[0020] Step 1: Arrange a plurality of stainless steel rods with a diameter of 5.5 mm to 8 mm compactly in the cavity of a circular tubular casting mold made of aluminum silicate plates. The length of the stainless steel rods is the same as the length of the casting mold. The stainless steel bars are arranged in parallel along the extension direction of the casting mold, and 100 stainless steel bars are placed inside the cavity of each casting mold at a time.

[0021] Step 2: Place the casting mold loaded with the stainless steel bars in a high-temperature vacuum environment, and maintain the temperature at 950°C to 1050°C. Cast molten pure iron into the cavity of the mold from the openings at both ends of the tubular casting mold, fill the remaining space inside the cavity of the casting mold with molten pure iron...

Abstract

The invention relates to a metal fiber production technology. The metal fiber production technology has simple processes, can be operated simply and has a low cost. The metal fiber production technology comprises putting multiple stainless steel bars into the cavity of a casting mold, wherein the stainless steel bars are arranged in parallel along a casting mold extension direction, putting the casting mold in a high-temperature vacuum environment, filling the cavity with melt pure iron, taking out the cooled first casting part from the casting mold, orderly carrying out turning, cogging and rolling on the first casting part to obtain a first wire rod, cutting the first wire rod into multiple wire rods with the same length along the cross section of the first wire rod, repeating the above processes on the first wire rod to obtain a second wire rod, orderly carrying out multi-channel drawing and annealing treatment on the second wire rod to obtain a composite filament, carrying out electrolysis in an acid solution based on the composite filament as an anode, washing the metal wires by distilled water and carrying out rinsing to obtain the metal fibers according with standards.

Description

technical field [0001] The invention relates to the field of metal processing, in particular to a metal fiber production process. Background technique [0002] In recent years, the metal fiber industry has become a rapidly developing new industry. With the development of society and the continuous improvement of people's living standards, the production standards for metal fibers are getting higher and higher. Metal fiber sintered felt is a porous deep filter material made of stainless steel fibers sintered at high temperature, with high porosity and high dirt-holding capacity. The minimum wire diameter of the metal fiber can reach the micron level. The existing production process of metal fibers generally includes: tube loading, copper plating, clustering, drawing, annealing, and stripping. The metal fibers produced by this process will cross and squeeze each other during the forming process. , resulting in poor smoothness of the metal fiber surface, and a large differenc...
