  • Method for producing a cast strip of molten metal and cast strip
    Patent number: 10179363
    Abstract: A method for producing a cast strip of molten metal, in which the molten metal passes through a casting gap defined by two oppositely rotating casting rollers and is shaped into the cast strip, as well as the cast strip that is produced. By providing the cast strip in the casting gap with a different thickness in a first length section extending in the longitudinal direction of the cast strip than in a second length section bordering thereon, a metal strip is produced that has length sections with different thicknesses.
