A sheet conveying apparatus has a skew conveying correction roller pair 2 for conveying a sheet, skew conveying detection sensors 3a and 3b for respectively detecting a skew of a sheet and a sheet-end-position detection sensor 4 for detecting the side position of the sheet. The skew conveying correction roller pair 2 is skewed by a skew amount obtained by adding a first skew amount for correcting the skew of a sheet detected by the skew conveying detection sensor 3a and 3b and a second skew amount θ2 for correcting the side position of a sheet detected by the sheet-end-position detection sensor 4. After the sheet is nipped by the skew conveying correction roller pair 2, the skew conveying correction roller pair 2 is skewed by the first skew amount θ1.

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.

To provide a sheet conveying apparatus capable of improving a correction accuracy for conveying a sheet. Accordingly, a “sheet conveying apparatus for conveying a sheet using a sheet conveying unit arranged along a sheet conveying path” according to the present invention includes a skew detecting unit for detecting skew of the sheet conveyed along the sheet conveying path with respect to a sheet conveying direction, a skew correcting unit that moves in a direction for correcting the skew of the skewed sheet with the sheet nipped therein on the basis of a detection signal from the skew detecting unit, and a guide unit for regulating side edges of the sheet and guiding the sheet to the skew correcting unit, in which, when the skew correcting unit moves in the direction for correcting the skew of the sheet, the guide unit is moved in the direction for correcting the skew of the sheet.
