Abstract

A method and a belt casting device for producing thin billets, in particular composed of steel, has an endless belt to which liquid metal is supplied via a feed device which has a casting channel and is connected to a metallurgical vessel. In this case, the feed device is in the form of a casting channel which has a first casting channel part in the form of a restriction channel part, and which has a second casting channel part whose opening faces the endless belt and whose size corresponds to the cross-sectional area of the finished product. The feed device is connected to a container to which liquid melt can be fed from a metallurgical vessel. Measurement elements are provided, which can be used to detect the level of the liquid melt in the container and/or the thickness of the billet located on the endless belt. Furthermore, the measured values are connected via a measurement and control element to an actuator which is connected to an element for adjusting the outlet rate from the metallurgical vessel.
