ABSTRACT:
An apparatus for effecting a thickness-reduction rolling of a hot thin plate ingot provided with a continuous casting machine and a rolling mill has a widthwise rolling mill disposed between the continuous casting machine and the rolling mill for performing a width-reduction rolling of a thin plate ingot, and a bending device disposed between the widthwise rolling mill and the rolling mill for performing a bending work on the ingot in the longitudinal direction. The widthwise rolling mill applies a widthwise compressive strain to scale formed on the surface of the hot thin plate ingot and the bending device applies strain in the longitudinal direction thereof to thereby form intersecting cracks for fining the scale formed on the surface of the thin plate ingot. The scale is thereafter easily exfoliated by a relatively low pressure water descaling device without excessively lowering the temperature of the ingot.
