ABSTRACT:
A method and an apparatus for the continuous manufacture of a metal strip (1) with near net shape. The metal melt (6) is fed from a melt distributor (5) through a casting nozzle (15) onto a rotating, cooled conveyor belt (2) and solidified. In the operating condition, the melt level is controlled in the melt distributor (5) as a function of the desired strip thickness d of the metal strip (1). In the melt distributor (5) there is initially adjusted a fill level (A), which corresponds at a maximum with the conveyor belt plane (E). Such a fill level (B) then is adjusted such that the melt (6) completely displaces the air from the area (11, 14) in front of the casting nozzle (15) and from the casting nozzle (15). In the operating condition, the fill level (C) is controlled some millimeters above the level (D) of the liquid metal on the conveyor belt (E) so that the melt (6) flows out of the casting nozzle (15) according to the pipette principle.
