Abstract

PURPOSE:To laminate smoothly without flaw, not causing scratch flaw and other defects on the billets, by letting off billets onto biling device to laminate while forming water film between biler unit and billet or between billets. CONSTITUTION:A billet 1 stopped in the let-off position of a conveying table 2 is pushed out by an advance command signal from a pusher unit 3. In cooperation with the advance command signal of the unit 3, an electric water valve 10 linked to an electric circuit is opened by a slight extent by means of a first valve control device 11. That is, by opening this valve 10, water is sprinkled in parabolic form onto a biling device 5 when letting off the billet 1 of the initial loading, and onto the billet 1 when the billet of the previous loading is positioned on the device 5. Several seconds later, the value 10 is fully opened by a second valve control device 12, and the water is violently injected into the lower surface of the moving billet 1 by means of the unit 3. Thus, the billet 1 is allowed to slide smoothly while perfect water film is being formed on the sliding surface, and is pushed onto the device 5, and the valve 10 is closed at the same time to return the unit 3 to the waiting position.
