Abstract
A process and apparatus for producing a metal strip using a two-roller casting device formed by two oppositely rotating casting rollers with parallel casting-roller axes and two side plates which bear against end sides of the casting rollers. The metal melt is conveyed out of the casting gap formed by the casting rollers as an at least partially solidified metal strip. To improve the sealing of the melt pool at the start of casting and in the event of parasitic solidifications passing through the casing gap, the side plates during a first time interval are moved onto the end sides of the casting rollers in a first direction of movement parallel to the casting-roller axes, and the side plates during a second time interval, are moved onto a portion of the lateral surfaces of the casting rollers in a second direction of movement parallel to the casting direction in the casting gap.
