AbstractSemisolid metal forming (SSF) is recognized as a new forming technology, which has been paid more and more attention by the researchers all over the world. The semisolid rolling process (rheo-rolling) combines the fabrication of semisolid slurry with continuously rolling as an important neoteric means to achieve near-shape forming. Compared with the traditional rolling process, this technology has the features of short machining process, low energy consumption, low cost equipment and high yield. However, one of the difficulties of using this technology to produce strip is that the solid and liquid phases prone to separation with each other during rheo-rolling deformation, especially when the semisolid slurry has a low solid fraction. The phenomenon causes macrosegregation and reduces the quality of the strip, as a result, limiting its industrial application. Using rectangular groove roller may solve this problem. In this paper, the mathematical model of unit rolling pressure distribution in rectangular groove during rheo-rolling was established. AZ91D magnesium alloy was taken as an example, and the effects of rolling strip thickness, width and roller radius on unit pressure were calculated and studied. The calculation results reveal that the smaller the thickness of rheo-rolled strip is, the narrower the width is, the bigger the peak unit rolling pressure is and the larger the average unit rolling pressure is However, when the strip thickness decreases, the peak unit rolling pressure moves towards the exit while when width decreases, the peak unit rolling pressure moves towards the entrance. The larger the roller radius is, the bigger the peak unit rolling pressure is, the larger the average unit rolling pressure is, and the peak value deviates towards the exit.
