    • A rolling reaction/rolling position controller (1) determines the position of a reference rolling roll at which the thickness of a solidification portion of an unsolidified slab attain a target thickness Tref, calculates the difference DELTA T between the thickness Tin of the unsolidified slab on the entry side of the rolling roll train PRT and the target thickness Trf, gives a target rolling position at which DELTA T is obtained to a rolling controller (2) of a reference rolling roll, and gives target rolling positions 1/3 DELTA T and 2/3 DELTA T to the rolling controllers (2, 2) for rolling rolls two rolls upstream of the reference rolling roll. Further, the rolling reaction/rolling position controller (1) calculates a target pressure (Pi + alpha ) from a predetermined alpha value of the steel kind and Pi = (Po x S)/A and gives it to each of the rolling controllers (2, 2) for the rolling rolls on the downstream side of the reference rolling roll.
    • 轧制反应/轧制位置控制器(1)确定未固化板坯的凝固部分的厚度达到目标厚度Tref的参考轧制辊的位置,计算未固化板坯厚度Tin之间的差ΔTATA, 轧辊列车PRT的入口侧和目标厚度Trf将获得DELTA T的目标轧制位置给予参考轧辊的轧制控制器(2),并且给出目标轧制位置1/3 DELTA T和 2/3 DELTA T连接到轧辊的轧制控制器(2,2),轧辊在参考轧辊上游两辊。 此外,轧制反应/轧制位置控制器(1)从钢种的预定α值和Pi =(Po x S)/ A计算目标压力(Pi +α),并将其赋予每个轧制控制器 2)对于轧制辊在参考轧辊的下游侧。
