  • the width of the strand can reach several percent of the nominal width.
  • the Japanese Patent Application JP S 61232049 discloses a method for adjusting the width of a continuous casting mold. Specifically, the desired width of the mold, the changes in the mold width at the beginning and at the end of a continuous casting process and the casting speed are entered as parameters in a computing unit, which calculates suitable manipulated variables for adjusting the mold width from these input parameters. As a result, a high-speed casting is possible, in which the variations of the mold width are reduced, even if otherwise the mold width fluctuates greatly during continuous casting.
