| Abstract: | The semisolid squeeze casting is a new processing technology assembling the semisolid processing and the squeeze casting in a body. In this process the semisolid alloy with rheologic property is filled into mold and then solidified into form under pressure. But, its process parameters were only determined by processing test in former times because of lacking the design rules. Based on a large number of experiments and relative theoretic inference, the design formulas of main process parameters, such as the squeezing time, the squeezing force, the diameter and height of the casting gate were conducted in this paper. The results are useful for the design and control of the process and the equipments. |
