【発明の詳細な説明】 〈産業上の利用分野〉 本発明は、ステンレス熱延鋼帯及びステンレス冷延鋼帯
の連続疵取り研削ラインおよび研削方法に関するもので
ある。The present invention relates to a continuous flaw removal grinding line and a grinding method for a hot rolled stainless steel strip and a cold rolled stainless steel strip.
〈従来の技術〉 従来のステンレス熱延鋼帯、ステンレス冷延鋼帯の疵取
り研削設備を第２図により説明する。<Prior Art> A conventional flaw removal grinding equipment for hot rolled stainless steel strips and cold rolled stainless steel strips will be described with reference to FIG.

きず取り参照）。In FIG. 2, 12 is a payoff reel, 10 is a stainless steel strip, 11 is a slip sheet, 13 is a belt grinder, 14 is a tension reel, 15 is a paper winder / paper payoff reel, and 16 is a paper payoff reel / paper winder. Yes (see, for example, Iron and Steel Institute of Japan, 3rd edition Iron and Steel Handbook (VI), P455, Fig. 11.28, "Example of arrangement of multi-stage mechanical polishing equipment"; Nikkan Kogyo Shimbun, Stainless Steel Handbook, P624, coil flaw removal) .

ステンレス鋼帯10に間紙11が挿入される。The stainless steel strip 10 is loaded on the pay-off reel 12, the leading end thereof is guided, and wound on the tension reel 14.
The stainless steel strip 10 is applied with a prescribed tension between the payoff reel 12 and the tension reel 14, and the belt grinding device 13
By this, the surface is ground and flaws are removed. At that time, on the pay-off reel 12 side, the interleaving paper 11 inserted in the previous process for preventing flaws is a paper winder and paper pay-off reel.
On the tension reel 14 side at the same time it is wound up by 15,
The interleaving paper 11 is inserted into the stainless steel strip 10 by the paper payoff reel / paper winder 16.

変更し、疵取り作業を完了する。The number of heads of the belt grinding device 13 is related to the depth of flaws of the stainless steel strip 10, but is generally 3 to 5 heads.
As the number of heads increases, the amount of grinding per pass also increases.
Pass grinding is also possible, but increasing the number of heads increases the tension required for grinding and increases equipment costs. Therefore, as described above, it is general to use 3 to 5 heads, and when the flaw cannot be removed, the return grinding is performed. The turn-back grinding means that the pay-off reel 12 is a tension reel and the tension reel 14 is a pay-off reel, and reverse grinding is performed to perform leftward grinding. Therefore, the paper winder / paper payoff reel 15 is used as a paper payoff reel, and the paper payoff reel / paper winder 16 is used as a paper winder. Then, turn-back grinding is performed, and when the flaw becomes shallower, the grinding is changed to right-going grinding, and the flaw removal work is completed.
〈発明が解決しようとする課題〉 上述のように、従来のステンレス鋼帯の疵取り研削設備
は、次のような問題がある。<Problems to be Solved by the Invention> As described above, the conventional flaw removal grinding equipment for a stainless steel strip has the following problems.
１パスで疵取り研削を完了するには、ベルト研削装

ベルト研削装置を多ヘッド設置すると、研削に必要
な張力が増加し、設備費が多大となる。If a belt grinding device is installed in multiple heads, the tension required for grinding increases, and the equipment cost increases.
ベルト研削装置を多ヘッド設置しない場合は、折り
返し研削を行うため能率が悪くなり、結果的に設備基数
を増やす必要がある。If the belt grinding machine is not installed in multiple heads, the efficiency of the grinding is reduced because the grinding is performed in a folded manner, and as a result, it is necessary to increase the number of facilities.
更に、この設備は鋼帯を連続的に処理できないた
め、研削装置にステンレス鋼帯を通板するのに時間を要
するため能率が悪いという欠点がある。Further, since this equipment cannot continuously process the steel strip, it takes time to pass the stainless steel strip through the grinding device, resulting in inefficiency.
また、研削面に油が付着しているため、研削面の検
査がやり難いという欠点もある。Further, since oil adheres to the ground surface, it is difficult to inspect the ground surface.
