【発明の名称】高温の薄板鋳片を減厚圧延する方法及び装置
Document Type and Number:
Japanese Patent JP2585529
Kind Code:
B2
Abstract:
An apparatus for discaling a hot thin plate (6) between a continuous casting machine (100) and a rolling mill (170). A widthwise rolling mill (150) is disposed between the continuous casting machine (100) and the rolling mill (170) for effecting a thickness-reduction of a thin plate the widthwise rolling mill being adapted to perform a width-reduction rolling of a hot thin plate manufactured by the continuous casting machine thereby applying a widthwise compressive strain to a scale formed on the surface of the hot thin plate. Bending work means (160) are disposed between the widthwise rolling mill (150) and the rolling mill (170), the bending work means (160) being adapted to perform a bending work of the hot thin plate in the longitudinal direction thereof thereby fining the scale formed on the surface of the thin plate and thus exfoliating the scale from the thin plate wherein the widthwise rolling mill (150) has widthwise rolling rolls (151) for effecting the width-reduction rolling of the hot thin plate and pinch rolls (152,153) provided respectively on the front and rear sides of the widthwise rolling rolls (151) along the longitudinal direction of the ingot, wherein the bending work means (160) has upper and lower bending rollers (161,162,163) zigzag disposed above and below the thin plate and a vertically driving means (90,91) for vertically moving one of the bending rollers (162), and wherein a thickness-reduction rolling of the hot thin plate ingot from which the scale has been thus removed is effected by the rolling mill.
