Abstract

The invention relates to a method for collecting and evacuating run-off water from the inner arc of the strand guide (8) of a beam blank casting machine, according to which the cast strand (2) is solidified and the required dissipation of heat is achieved, among other things, by sprayed water, whereby run-off water can also collect on the inner arc of the strand (2). The run-off water is collected using a suction head (1). The run-off water that is collected in the suction head is fluidized using fluidizers or momentum inhibitors. The fluidized water is sucked off and the water-air mixture is split into water and air in a separation device. The invention also relates to a device for carrying out said method, comprising at least one suction device that is arranged or can be driven along the strand guide (8), said suction device having an attachable suction head (1) and being equipped with fluidizers. The suction device (4) is driven along the beam blank preliminary section (9) by means of manipulators (7).
