    摘要： In continuous casting a thin carbon cast strip, the scale formed thereon is made thin and made to have a composition suited to working such as cold rolling and pressing. Moreover, an apparatus for inhibiting scale formation is simplified, and the consumption amount of an inert gas is reduced. The cast strip is thus produced efficiently. A carbon steel containing up to 0.5% of C is cooled and solidified by a pair of cooling drums to give a thin cast strip having a thickness up to 10 mm. The cast strip is introduced into a seal chamber, where the strip is held in an Ar gas atmosphere containing up to 5% of oxygen through a temperature region to at least 1,200.degree. C., and the strip is cooled at a rate of at least 10.degree. C./sec through a temperature region to 750.degree. to 800.degree. C., followed by coiling the strip in a coil form with a coiler at a temperature of at least 500.degree. C. and up to 800.degree. C. Furthermore, the atmosphere is formed with a nitrogen gas or exhaust gas. The scale formation is inhibited, and the composition of the scale is controlled by the use of the atmosphere.

    摘要： A twin drum-type continuous casting process for casting thin cast strip by solidifying molten steel continuously fed between a pair of cooling drums placed parallel to each other, wherein the cooling drums are given an added degree of concave crown such that a solid fraction at the thickness center of the thin cast strip, when the distance from the edges toward the center of the thin cast strip at the closest position of the cooling drums is within 50 mm, is exhibited which is a value greater than the fluid critical solid fraction, or alternatively the cooling rate near the edges of the cooling drums is improved.

    摘要： 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}{square root over (R)})×P≦2.0, and preferably 0.8≦({square root}{square root over (R)})×P≦1.2.
