【発明の詳細な説明】
〔産業上の利用分野〕
本発明は、母材１ｎ度を１００％活かした上で、母材表
面を硬質炭化クロム複合合金Ｍ（ダイクロン処理）によ

の請度を更に高めた紙の厚さ検知用ローラに関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention utilizes 100% of the 1n degree of the base material, hardens and modifies the base material surface with a hard chromium carbide composite alloy M (Dyclone treatment), Then, it relates to a paper thickness detection roller that has been ground and polished to further improve the quality of the final product.
従来の母材に対する表面硬化技術としては１例えば下記
に示すようなものがある。Examples of conventional surface hardening techniques for base materials include the following.
［１１ずぶ焼入れ（母材全体を焼入れする）−殻内には
この焼入れ方式が最も多く利用されているが５本発明で
論じている長尺物では特にひとい歪みや曲がり（０６２
〜１．Ｏｍ會）を生じ、ｌ＆工程での歪み取り、 １１
１１がりの矯正、研削加工等が難しく、後処理が煩雑で
高価となる。[11 Deep hardening (hardening the entire base material) - This hardening method is most often used for the inside of the shell, but 5 It is particularly difficult to cause distortion or bending in the long objects discussed in this invention (062
~1. Om meeting) and distortion removal in l & process, 11
11 It is difficult to correct the edges, grind, etc., and post-processing is complicated and expensive.
（２）高周波焼入れ 高周波の熱により部分焼入れが可能であるが。(2) Induction hardening Partial hardening is possible using high-frequency heat.
高温度のため上記（１）と同様に母材に対して歪みや曲
がりが生じ易く、錆等の発／Ｐ、もありＶ＃る。Due to the high temperature, the base material is likely to be distorted and bent, as in (1) above, and rust, etc. may occur.
（３）浸炭焼入れ
ある条件の雰囲気・環境中で炭素を母材に浸這させて表

ず、請度出しが劣る。更に、錆の発生（ステンレス材を
除く）を住う。(3) Carburizing and quenching Carbon infiltrates into the base material in a certain atmosphere and environment to harden the surface layer, but the hardened layer is thin and uneven, and the long base material still causes distortion and bending due to high temperatures. In addition, due to this bending, the material is ground unevenly during the grinding process of l&, exposing the base material fabric, making it difficult to ensure hardness and resulting in poor bending. Additionally, rust may occur (except for stainless steel materials).
（４１表面窒化
浸炭焼入れと同様で炭素の代わりに窒素により硬化を行
うが、浸炭焼入れと同様の欠点がある。(Similar to 41 surface nitriding carburizing and quenching, hardening is performed using nitrogen instead of carbon, but it has the same drawbacks as carburizing and quenching.
（５）化学メツキ
母材表面に電解または無電解により母材表面とは異種の
金属膜（または金属層）を形成させるため、母材表面と

り剥離し易く、精度が不確実で、精度出しのための追加
加工等ができない。(5) Chemical plating In order to form a metal film (or metal layer) of a different type from the base material surface on the base material surface by electrolysis or non-electrolysis, it is independent from the base material surface, and is free from mechanical external forces. It is easy to peel off due to the influence of oxidation, the accuracy is uncertain, and additional processing for accuracy cannot be performed.
（６）その他の表面処理
硬質金属をコーティングまたはブレーティング等拡散技

１１度出しの追加加工は困難で。(6) Other surface treatments Attempts have been made to harden the surface of hard metals by diffusion techniques or vapor deposition techniques, such as coating or brating, but the i temperature causes distortion and sagging of the base material, resulting in poor accuracy. 81
Additional processing at 11 degrees is difficult.
後処理方法が高価である。Post-processing methods are expensive.

For products that require surface hardness, precision, and abrasion resistance, the surface hardening methods described above may cause distortion, bending, etc. due to the effects of high temperature atmosphere on the precision of the long base material. In addition, it is difficult or impossible to perform machining in the subsequent process to ensure accuracy.

exists, and the thickness t of the hard chromium carbide composite alloy layer 3
After tl is formed, the thickness t2 is removed by 1 gF grinding and polishing to obtain a thickness (tl - t2) that sufficiently maintains the surface area.
) is approximately 11V12 as hard chromium carbide composite alloy FJ3.
It is left on the roller surface with a hardness of around 0.00. here,
The thickness Ll of the hard chromium carbide composite alloy FJ3 must be greater than or equal to the maximum distortion/bending T of all the convex rollers l of the ft-length roller. Figure 3 shows the hard chromium carbide composite alloy treatment for surface hardening of the long roller. It is a figure which shows the example of a machining process and straightness accuracy before and behind. A ferrous or non-ferrous base material with a certain degree of accuracy with a long roller (Fig. 3) The straightness after the turning process of Ta+ is 0.2 mm, and grinding and IIIF polishing are performed with a grindstone 5 (Fig. 3, BL). 1st grinding/
After the polishing process, the straightness is 0.05mm), a hard chromium carbide composite alloy layer with Il+ lubrication performance and wear resistance is formed on the 9 surface to harden and modify the surface (Figure 3 (hardening of C1). After the modification a), further secondary machining, that is, grinding and polishing using the grindstone 5 (the straightness after the secondary grinding and polishing process in Figure 3 + dl is o, oos). Therefore, in addition to performing surface hardening modification on long rollers having such uneven surfaces, it is possible to maintain a very high final stiffness and also ensure economical efficiency. The same applies not only to the chromium carbide composite alloy layer 3 but also to other electroplating treatments.
