Method of Manufacturing Martensitic Stainless Steel Sheet Using Twin Roll Strip Caster

摘要

A method of manufacturing a martensitic stainless steel sheet by allowing ingot steel to pass through two casting rolls rotating in opposing directions through a twin roll strip caster is provided. The method includes rolling a steel sheet cast between the casting rolls at a temperature of 1000 to 1200° C. and a draft percentage of 25 to 50% with a first roller, and rolling the steel sheet at a temperature of 800 to 1000° C. and a draft percentage of 5 to 15% with a second roller.

1. A method of manufacturing a martensitic stainless steel sheet by allowing ingot steel to pass through two casting rolls rotating in opposing directions through a twin roll strip caster, the method comprising:
performing a first rolling process of rolling a steel sheet cast between the casting rolls, with a first roller, to induce recrystallization to occur; and performing a second rolling process of rolling the steel sheet having been subjected to the first rolling process, with a second roller, to generate carbon precipitation sites.
