Methods for casting an austenitic stainless steel thin strip casting through a continuous caster, e.g., a twin-drum type caster, in which the mold walls move synchronous with the casting to obtain a casting, wherein defects, e.g., salt-and-pepper unevenly glossy defects, on a steel sheet formed after cold rolling or cold forming are prevented. In particular, casting an austenitic stainless steel thin strip casting by regulating a pressing force P of mold wall faces against the casting in the range from more than 1.0 to less than 2.5 t/m, and preferably from more than 1.1 to not more than 1.6 t/m. The continuous caster used may be a twin-drum type continuous caster, with a drum radius R(m) and a pressing force P(t/m) of mold wall faces satisfying the relation 0.5≦(√{square root over (R)})×P≦2.0, and preferably 0.8≦(√{square root over (R)})×P≦1.2.
A method for producing an austenitic stainless steel thin strip casting through a continuous caster wherein mold walls move synchronously with the casting, comprising applying a pressing force P of the at least one mold wall face against the casting wherein the pressing force is more than about 1.1 and less than about 1.6 t/m.
A method for producing an austenitic stainless steel thin strip casting through a continuous caster wherein mold walls move synchronously with the casting wherein the continuous caster is a twin-drum type continuous caster, and wherein the drum radius R (m) and the pressing force P (t/m) of at least one mold wall face satisfies the relation 0.8≦(√{square root over (R)})×P≦2.0.
A method for producing an austenitic stainless steel thin strip casting through a continuous caster wherein mold walls move synchronously with the casting, comprising applying a pressing force P of the at least one mold wall face against the casting is more than about 1.1 and less than about 1.6 t/m, and the drum radius R (m) and the pressing force P (t/m) of at least one mold wall face satisfies the relation 0.8≦(√{square root over (R)})×P≦2.0.
