摘 要：In semi-solid forming process, preparing the slurry with rosette or globular microstructure is very important. A new ap- proach named the damper cooling tube method （DCT）, to produce the semi-solid metal slurry, has been introduced. To optimize the technical parameters in designing the apparatus, the finite volume method was adopted to simulate the flow process. The temperature effects on the rheological properties of the slurries were also considered. The effects of the technical parameters on the slurry proper- ties were studied in detail.
