| 總結: | This study addresses effects of die temperature on flow line and cold shut in aluminum die casting operation. The factors incorporated in the experiment were water flow rate and lubricant spray time on the die face. The experiment utilized the fixed effects model and analysis of variance. The study showed that main factors which control flow line and cold shut were water flow rate, lubricant spray time and interaction between them with level of significance of 0.05. Factors that controlled the die temperature were water flow rate through die, lubricant spray time and interaction between them with level of significant of 0.10. The water flow rate through die helped maintain the die temperature and it was found that the lubricant spray time on die face could rapidly change the die temperature. The optimum condition found by experiment occurred at the water flow rate between 6.7-7.2 liter/minute, 2 seconds of lubricant spray time and 131-140 ํC of the die face temperature. The conditions yield work pieces having hardness of 104 BHN and fine eutectics structure. |
