【発明の詳細な説明】 （産業上の利用分野） 本発明は、ステンレス鋼製のキヤステイングベルト材の
製造方法に関する。Description: TECHNICAL FIELD The present invention relates to a method for manufacturing a stainless steel cast belt material.
（従来技術とその問題点） ステンレス鋼製のキヤステイングベルトは、そのベルト

な事、ベルト材の表面がきわめて平滑でピンホールや非
金属介在物の存在が認められない事などである。(Prior Art and Problems Thereof) Stainless steel cast belts are used for industrial production of various films including photographic films as a base for casting resin films on the belt surface. The functions required for this casting belt material are that it has good corrosion resistance, that it has sufficient strength as a belt material and that its surface hardness is sufficiently large, that its flatness is extremely good, that the surface of the belt material is extremely smooth and has pinholes. And the existence of non-metallic inclusions is not recognized.

したがって、キヤステイングベルト材の製造では、ある
程度良好な鋼帯を製造し、その中から特に形状や平坦度
の良好なものを選択しているのが、実状である。The most difficult point in manufacturing the stainless steel cast belt is to simultaneously satisfy high strength or high hardness and extremely good belt flatness.
Generally speaking, in order to increase the strength of stainless steel, a method of work hardening austenitic stainless steel by cold rolling is used, but in the state of cold rolling, stable and excellent flatness is obtained. Is difficult to obtain, and subsequent straightening is also difficult due to the high strength of the steel strip.
Therefore, in the production of the casting belt material, a steel strip having a certain degree of goodness is produced, and a steel strip having a particularly good shape and flatness is selected from the actual situation.
一方、近年キヤステイングベルト材の表面品質に対する

溶解法も用いられている。これは不可避的に素材費用の
著しい高騰をもたらす。On the other hand, in recent years, the required level for the surface quality of the casting belt material has become extremely strict. Is becoming insufficient. Therefore, in recent years, special melting methods, especially high frequency vacuum melting, vacuum arc melting, and electroslag melting have been used in the production of raw materials, and in order to achieve completeness, these two or three combination melting methods are also used. It is used. This inevitably results in a significant rise in material costs.

希望することに応えられないという問題がある。Therefore, if the casting belt material is manufactured by cold rolling using the materials produced by the special melting method or the composite melting method combining them, and the good one is selected from them, the casting belt material is However, there is a problem that the manufacturing cost of the product increases dramatically, and it is not possible to meet the demand of the user for an inexpensive and high quality belt.

したものである。(Means for Solving the Problems) The inventors of the present invention can clad an ultrahigh-purity stainless steel in a normal stainless steel as a base material, and use the ultrahigh-purity stainless steel strip side of the clad material as a functional surface. The present invention has been completed by finding that a belt material having a sufficient function can be obtained by significantly reducing the amount of expensive special melting material used.

る。In the present invention, as a method of clad the ultra-high purity stainless steel and the base material stainless steel, the usual slab assembly hot rolling method is the most suitable, but the two coils are diffusion-bonded by a winding method, etc. A method of subjecting to cold rolling can also be used. In either case, it is preferable to use the same type of material for the base material and the high-purity functional material on the surface for shape control during hot rolling and cold rolling, but with different functions such as strength and corrosion resistance. It is also possible to share the base material and the surface material. A functional material clad ratio of 5% is sufficient,
It is preferable to have about 10% with a margin such as a polishing allowance.
