Abstract: The invention is directed to a device for casting strands of metal, in particular steel, with a material supply vessel, the liquid metal being delivered to the carrying side of a circulating conveyor belt by means of the pouring nozzle of the material supply vessel. The conveyor belt comprises a thin, heat-resistant belt which circulates between a first deflection roller and a second deflection roller and which is shaped after the first deflection roller and in the region of the outlet nozzle to form a trough for receiving the liquid metal and resumes the shape of a flat belt in proximity to the second deflection roller. In order to reduce stresses on the belt, it is proposed that at least one of the deflection rollers is cambered in a convex manner.
