1. one kind is carried out the local method of controlling to hot-fluid in the process of continuous casting thin cast strip, and this method comprises the steps:

  • The casting roll of a pair of reverse rotation laterally is installed,, is cast out by this roll gap metal tape to form the roll gap between the periphery casting surface of casting roll;

    Form the casting molten bath of motlten metal, described molten bath is supported on the surface of described casting roll, and is positioned at the roll gap top, thereby forms the casting zone;

    Rotating brush is installed in the periphery, and with before motlten metal in casting is regional contacts, described brush contacts with the casting surface of each casting roll at casting surface;

    Casting surface by each casting roll contacts with rotating brush, removes the oxide on the casting surface of each casting roll;

    The casting surface that enters between the place to described rotating brush and casting zone is carried gas, to form gas blanket on the removed position of oxide on the casting surface of each casting roll;

    AndCasting roll is rotated on the contrary, make the casting surface of each casting roll move, thereby produce from the downward casting band of roll gap to roll gap.
