    • The present invention discovers that a rolling direction force occurs even with conventional adjustment by the kiss roll state, pinpoints that the rolling direction force does not affect the roll thrust force, and thereby enables more precise initial roll gap position adjustment of a rolling mill (rolling zero adjustment).That is, this is based on the fact that high precision rolling zero adjustment becomes possible without being affected by any thrust force acting between rolls if performing differential asymmetrical roll gap zero point adjustment of the work side and the drive side so that the difference of the rolling direction forces acting on the roll chocks of the work side and the drive side of the work roll at the work side and the drive side (in practice, within ±5% of the sum of the rolling direction forces at the work side and the drive side).
    • 本发明发现即使通过接触辊状态的常规调整也发生轧制方向力，指出轧制方向力不影响轧辊推力，从而能够实现轧机的更精确的初始轧辊间隙位置调整（轧制 零调整）。 也就是说，这是基于以下事实：如果执行工作侧和驱动侧的差分不对称辊隙零点调整，则不会受到在辊之间作用的任何推力的影响而实现高精度滚动零点调整，使得 作用在工作侧的辊轴承座和工作辊的驱动侧的工作侧和驱动侧的轧制方向力（实际上在工作侧的轧制方向力的总和的±5％以内 驱动侧）。
