Using the same material and rolling schedule, two types of experiments were carried out. One is the twohigh rolling mill without backup rolls, where only the thrust force F AWS can be measured. The other is a fourhigh rolling mill, where the resultant total force F A of F AWS and F AWB can be obtained. The results are shown in Fig. 4.
However, the turntable type is complicated in its mechanism and requires an increased space, so that it cannot be practically employed in a continuous rolling mill in which the distance between each roll stand unit is small. Further, in a fourhigh rolling mill, even when the turntabletype is used for changing working rolls, Chook and the ...
