FIELD: steel strip rolling.
SUBSTANCE: first steel strip and the second steel strip are rolled in one rolling stand of the cold rolling mill. Between the rolling of the first steel strip and the rolling of the second steel strip, there is a pause. The first steel strip is fed to the rolling stand exiting the first decoiler along the first path and is not heated during feeding to the rolling stand. The second steel strip is fed to the rolling stand exiting the first decoiler or from a second decoiler different from the first decoiler along the second path and is heated during the supply to the rolling stand. The second path is longer than the first path.
EFFECT: possibility of rolling brittle and easily breaking steel strips in a batch cold rolling mill without the danger of cracking the strip.
