碩士 === 國立高雄第一科技大學 === 機械與自動化工程研究所 === 104 === Because renewable energy development is bound to protect the development trend of the global environment with the increasing scarcity of energy in the world, people are more and more showing solicitude for energy-saving and environmentally.In this study,we discuss about the effects of coil design on high frequency induction heating process for Aluminum foams. We use SS400 low carbon steel as mold,then we move workpiece with ball bearing slide and the coil is fixed.The workpiece is heated by coil which device on the induction heater.We change the coil to test about the effects of coil design on induction heating process for Aluminum foams. We use coil diameter, coil turns, the inner diameter of the coil and output current as control parameters. Through investigate the effect of control parameters on aluminum foam, the foam in order to improve the uniformity of the holes, porosity and pore size of the foamed aluminum, in terms of mechanical properties, compressive strength than as an index to explore aluminum foam compression feature comparison strength Objective of this study is the use of high frequency induction heating coil mechanism aluminum foam can be manufactured integrally molded foam of the long aluminum pipe, no need for secondary processing to the welding process, and has no need to have the advantages of the mold, while reducing the heat source of the mold the impact of the foam manufacturing process to improve the current shortcomings of the comprehensive results of this study are as follows: 1 brass outer diameter of the induction coil turns, preheat current heated argument with the current growth rate of the workpiece relative axial feed rate to be higher induction coil with an inner diameter of the growth parameters, workpiece relative to the axial velocity must slow down the feed rate; 2 in the foamed aluminum ratio uniformity and compressive strength of the relationship between holes, and coefficient of variation of the ratio of compressive strength graph can be learned substantially negative response relationship..
