Abstract:
The present invention relates to a production method for a hot rolled strip in a hot rolling line. An object of the present invention is to ensure stable running of a hot rolled strip on a hot runout table, and to prevent excessive displacement of the hot rolled strip above a pass line, and, for example, a head folding defect and a tail folding defect resulting from the displacement. In the method of the present invention, a fluid jet is squirted above a hot rolled strip conveyed by a hot runout table so as to pass over the hot rolled strip running without touching a surface of the hot rolled strip running on a pass line (a strip-conveying surface of the hot runout table). A strip portion displaced upward from the pass line beyond a predetermined level collides with the fluid jet, and the displacement of the strip portion is thereby corrected. Since the fluid jet passes over the normally running hot rolled strip without touching therewith, the strip portion is properly prevented from being displaced by squirting the fluid jet.
