Roller forces were measured for the straightening zones (a vertical bending zone and an unbending zone) of a continuous casting machine of a vertical bending type, and the obtained data were analyzed. Further, some numerical calculations were carried out and the measured values of the roller forces were analyzed theoretically.
The following facts were elucidated :
(1) Very large roller forces appear when a slab head or a slab tail goes through the unbending zone.
(2) The roller forces are larger at the exit of the unbending zone than those at the entrance.
(3) The correlation between roller forces and slab width is not distinct and contrary to usual anticipation, the roller forces are not proportional to slab width.
(4) The characteristics of the straightening forces in the vertical bending zone are the same as those in the unbending zone.
