Abstract: In continuous casting rolling process, the deformed body is different from the hot rolling strip. The metal in casting rolling zone is first assumed to be viscous fluid and the mathematical model of casting rolling force is established, then the calculating formula for casting rolling torque is derived. In addition, considering the effects of deforming cone and appendant torque of rotary junction＇s sealing ring, the calculating model which accords with casting rolling condition is found out. Theoretical formula is proved by experiment.
Key words: continuous casting rolling; moment model; plate and strip; viscous fluid
