In casting‐rolling process the velocity is very slow and, therefore, the deformed body is still in the state of liquid‐solid viscous flow. The rheological properties of the deformed body are described by the theory of mature hydromechanics. A velocity field was set by the flow function. The pressure field and velocity field of metal flow were combined, based on Navier‐Stokes equation. The distributional formula of the unit pressure in the deformed zone was obtained, and the calculation formulae for mean unit pressure in the casting‐rolling zone were established. In this paper, the influence of absolute draft, radius of casting‐rolling roll and front tension stress on the mean unit pressure had been discussed. Comparison of theoretical data with experimentally obtained values showed good agreement, thus proving the correctness of the theoretical formulae.
