Abstract
The invention relates to a method for operating a strip casting machine (), whereby molten metal () is poured between two rotatable casting rolls (). A gaseous film (G) is formed between the respective surfaces () of the casting rolls and the strip skin (D, D, D) forming on the molten metal, the gas being introduced essentially into the inerting chamber () above the metal bath. During the casting, a controlled quantity of a gas consisting of argon, nitrogen and/or another gas is introduced into the inerting chamber () in such a way that the heat transfer from the strip skin to the casting rolls () can be influenced by the thickness of the gaseous film (G) in such a way that the surfaces (') of the casting rolls can be provided with or without cavities (). A smooth surface can thus also be obtained on the strip cast.
