As a conventional manufacturing method for metal fibers, a wire drawing method is known in which a metal wire is continuously drawn using a diamond die, and although this is the best method in terms of obtaining metal fibers with good roundness in cross section, The metal fiber produced by this method is expensive because it requires multiple wire drawing steps and requires sophisticated manufacturing technology.

この方法によれば、前記伸線法よりも繊維断面の
真円度は劣るが、より容易にかつ安価に金属繊維
を製造することができる。 In addition, as an inexpensive method for simultaneously producing a large number of metal fibers, a large number of composite rods made of fiber-forming metal on the inside and isolation material on the outside are filled in a tube material in parallel, and then hot-rolled. Japanese Patent Laid-Open No. 51-17163 describes a method in which the wire rod is rolled and then cold-drawn to form a fine wire, which is then immersed in acid to dissolve and remove the separator.
It is known from publications such as No. 1 and USP3394213.
According to this method, although the roundness of the fiber cross section is inferior to that of the wire drawing method, metal fibers can be manufactured more easily and at a lower cost.

In the conventional method of manufacturing a large number of metal fibers at the same time, in the process of manufacturing a composite bar consisting of a metal material and a separator, that is, in the method disclosed in Japanese Patent Application Laid-Open No. 51-17163, round billets of stainless steel are made into ordinary steel pipes. The material inserted into the wire is hot-extruded to form a square billet, which is then hot-rolled and then cold-drawn to produce a composite bar, which requires a large number of steps and reduces yield. However, manufacturing costs are high.

溶接して複合ビレツト２となす工程。(a) Carbon steel 11 on the surface of stainless steel billet 1
A step of overlaying and welding the billet to a thickness of 2 to 8% of the thickness of the billet 1 to form a composite billet 2.
複合ビレツト２は、つぎの工程で熱間線材圧
延されるので断面が正方形の角ビレツトである
ことが望ましく、サイズは一辺の長さが100mm
〜150mmのものが望ましい。 Since the composite billet 2 will be hot-rolled in the next step, it is preferably a square billet with a square cross section, and the size is 100 mm on one side.
~150mm is preferable.

ンレス鋼の成分に応じて選定することが望まし
いが、0.10％以下であれば問題ない。 If the C content in the carbon steel to be overlay welded is too high compared to the C content of the target stainless steel, C will diffuse into the stainless steel during overlay welding or in subsequent processing steps, causing the stainless steel to deteriorate. There is a risk of deterioration of the steel fiber material. Therefore, it is desirable to select the C content in carbon steel according to the components of the stainless steel, but there is no problem if it is 0.10% or less.

ツト１の厚さの２〜８％と限定した。 If the thickness of the overlay weld is less than 2% of the thickness of the stainless steel billet 1, it will become too thin during subsequent processing, and there is a risk that the stainless steel pieces will be crimped together, and if it exceeds 8%, the welding cost will increase. At the same time, the dissolution time in step (f) becomes longer. Therefore, the thickness of the overlay welding was limited to 2 to 8% of the thickness of the stainless steel billet 1.

本発明においては、肉盛溶接に限定した。 As a means of obtaining the composite billet 2, a method of plating the surface of the stainless steel billet 1 with carbon steel 11 or a method of thermally spraying the carbon steel 11 can also be considered, but in the plating method, the thickness of the stainless steel billet 1 is Furthermore, the composite billet 2 obtained by thermal spraying has the problem that the carbon steel peels off during hot rolling in the next step. Therefore,
