The apparatus utilizes twin casting drums and a cast-on site removed from a sump formed between the two drums. The apparatus forms a completely uniform continuous metal sheet without a molten center when the sheet emerges from between the casting drums. Complete solidification of the metal sheet does not take place on a single casting drum, allowing for sheeting of substantially greater thickness to be uniformly cast.

Arrangement for continuously casting a continuous metal sheet

When continuously casting a thin strip, metal melt is cast onto the drum surface of a first casting drum. A casting gap is formed by a second casting drum spaced apart with its drum surface from the first casting drum by the thickness of the strip. Strand shells form on the drum surfaces of the first and second casting drums. In order to enable the casting of strips having different thicknesses, a sump is formed at a distance from the cast-on site of metal melt on the drum surface of the first casting drum. Between the sump and the cast-on site on the drum surface of the first casting drum, a strand shell of a predetermied thickness is formed. The casting gap is adjusted in a position on the circumference of the first casting drum such that the two strand shells formed on the drum surfaces in terms of their maximum thickness, in total, correspond at least the thickness of the cast strip.
