The present invention relates to a method for manufacturing austenitic stainless steel sheet by cold rolling a slab having a thickness close to that of a product cast by a casting process.

グし冷間圧延して最終焼鈍を行うものであった。The conventional method of manufacturing stainless steel FM thin plates using the continuous casting method is to vibrate the mold in the casting direction and roll it to a thickness of 100 mm.
After casting the slab into slabs with a roughness of 100 lbs. The strip was then processed into a hot strip with a thickness of several mm, and then annealed if necessary, followed by descaling, cold rolling, and final annealing.

料としてのメリットがなくなる。When producing a stainless steel thin plate by continuous casting such as the above-mentioned twin roll method or twin belt method, there is an advantage that the conventional process from casting to the product can be significantly omitted and shortened. Generally speaking, one of the problems with stainless steel is that it is highly susceptible to localized corrosion such as pitting corrosion and crevice corrosion in aqueous solutions containing chlorides. For this reason, stainless steel with increased Cr, Mo, or N content has been developed as a new corrosion-resistant material. Of these elements, C
If r or Mo is increased, the cost will increase and there will be no merit as a general-purpose material.

ナイトステンレス薄板の製造方法によって解決される。According to the present invention, the above-mentioned problem can be solved by casting an 18-8 series austenitic stainless steel sheet into a strip-shaped slab using a continuous casting machine in which the mold wall surface moves in synchronization with the slab, cold rolling it, and annealing it. The present invention is solved by a method for manufacturing an 18-8 austenitic stainless steel sheet, which includes a step of cooling the thin strip-shaped slab in the area from directly below the mold to winding using nitrogen gas. .

窒素濃化層が表面に残存する。According to the present invention, when continuously casting thin strip slabs of 188 series austenitic stainless steel using the twin roll method etc., the slab from directly below the mold such as rolls to winding is cooled using nitrogen gas. Therefore, nitrogen gas penetrates into the surface layer of the slab, forming a nitrogen-concentrated layer. Since the generation of oxide scale in the obtained slab is suppressed by nitrogen gas, the amount of scale removed is small, and a nitrogen-concentrated layer remains on the surface even after descaling.

ない。18-8 where a nitrogen-concentrated layer was formed on the surface in this way.
When a thin strip of austenitic stainless steel is cold-rolled, annealed and optionally pickled to form a thin plate, the total reduction from the slab to the thin plate is significantly lower than in the conventional method, so it is possible to A nitrogen-concentrated layer also remains on the surface of the product. Therefore, the nitrogen enriched layer on the surface of the product improves corrosion resistance such as pitting corrosion resistance and crevice corrosion resistance. Furthermore, since the inner layer of the thin sheet product is not enriched with nitrogen, its original workability is not impaired.
