Method for producing a metal strip using a two-roller casting device

A process for producing a metal strip using a two-roller casting device wherein the device comprises:

• a melt pool formed by two oppositely rotating casting rollers with respective casting-roller axes arranged parallel to one another and by two side plates which bear against end sides of the casting rollers, and the side plates are formed of a material and a casting gap is formed by lateral surfaces of the casting rollers, the process comprising:
• introducing metal melt into the melt pool;
• conveying an at least partially solidified metal strip from the melt pool through the casting gap;
• during a first time interval, moving the side plates onto the end sides of the casting rollers in a first direction of movement parallel to the casting-roller axes, and
• during a second time interval, moving the side plates 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.
