Development of a new mold oscillation mode for high-speed continuous casting of steel slabs.

High-speed oontinuous casting is a prerequisite for the successful operation of hot direct rolling (HDR). However, as casting speed increases, breakout caused by solidified shell sticking tends to occur. It is therefore necessary to reduce the frictional force betweenthe mold and the solidified shell in order to prevent shell sticking in high-speed casting,
