Abstract：

|
The idea of producing metal semi-solid slurry using the device of twin-screw comes from the theory of polymer extruder used in injection industry,but they are not the same thoroughly.The device of twin-screw for metal semi-solid slurry preparation must be more efficient in shearing and mixing.Based on the above,the twin-screw and corresponding kneading blocks were designed,and the axial force occurred when the device in working condition was calculated.Besides,the production ability of metal semi-solid device was estimated and the contradiction between size of thrust bearing and center-to-center distance was solved.
