「産業上の利用分野」
本発明は、遠赤外線放射体用ステンレス鋼管の製造方法
に関するものである。DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a method of manufacturing a stainless steel tube for a far-infrared radiator.
「従来の技術」
近年、遠赤外線は、暖房機器はもとより、例えば塗装の

等、各種の産業分野において盛んに利用されている。"Prior Art" In recent years, far infrared rays have been widely used in various industrial fields, such as heating equipment, as well as drying and baking of paint, adhesion of plywood, and heating processing of various foodstuffs.

JP-A-55-6433 discloses a stainless steel heat dissipating body in which an oxide film is formed by treatment with any one of the sulfuric oxidation method, the alkaline oxidation method, the acidic oxidation method, or the electrolytic coloring method.

題があった。"Problems to be Solved by the Invention" By the way, the technology disclosed in the above-mentioned published patent application includes a polishing process to make the surface roughness of the stainless steel material 1μ or more, and a polishing process that oxidizes the surface after the polishing process. Stainless steel heat sinks are manufactured through two steps, including the oxide film formation process, which causes a film to be formed, so it is inefficient and harmful to the environment.In particular, mechanical polishing and nylon blasting, etc., generate noise and cause dust. There was a problem that the formation of layers caused significant environmental damage.

ければならず、生産性に著しく劣る問題があった。Further, the surface alan means and the oxide film forming means are:
Although they can be installed consecutively on the same line, it is not possible to send the stainless steel strip that has passed through the surface alan means and the oxide film forming means to the pipe production line continuously; After the stainless steel strip that has passed through the oxide film forming means is first wound into a coil, it must be made into stainless steel tubes in a separate tube-making line, resulting in a problem of significantly lower productivity.
本発明は、かくの如き従来の問題点を解決すべくなした
遠赤外線放射体用ステンレス鋼管の製造方法を開発した
のである。The present invention has developed a method for manufacturing a stainless steel tube for a far-infrared radiator, which solves the above-mentioned conventional problems.

。"Means for Solving the Problems" The gist of the present invention is to continuously supply a stainless steel strip subjected to Dulskin bath treatment to a pipe-making line,
This welded stainless steel pipe is passed through a sizing process with a roll surface roughness of 2 to 30μ to produce a welded stainless steel pipe with an outer surface roughness of 2 to 30μ.The welded stainless steel pipe is then heated to a high temperature. Pass it through an oxidizing atmosphere to generate an oxide film on its outer peripheral surface,
Our purpose is to manufacture stainless steel tubes for far-infrared radiators.

きる。``Function'' As mentioned above, the roughness of the outer peripheral surface of the welded stainless steel pipe itself, which is formed by continuously supplying the stainless steel strip subjected to the Dull Skin bath treatment to the pipe-making line, is on the order of micrometers. By passing a stainless steel pipe through a sizing process with a roll surface roughness of 2 to 30μ, a welded stainless steel pipe with an outer surface roughness of 2 to 30μ can be obtained; By passing the steel pipe through a high-temperature oxidizing atmosphere, an oxide film can be generated on the outer circumferential surface of the stainless steel tube, which can emit far-infrared rays from the outer circumferential surface.The conventional pipe manufacturing line is slightly modified. It can be efficiently manufactured at a certain level.
