【Abstract】 The design presented in this paper applied microcontroller control technology,used the vacuum-smelt technology and the casting technology using differential pressure.The design effectively eliminated the harmful influence of air in the process, overcame the aluminum-based compound material’s shortcoming of lacking fluidity in liquid form, and guaranteed the satisfactory of casting requirements of complex,thin-wall, and precision. In this paper, we introduced the composition of the smelting-casting stove control system and each part’s functionality.We also described the process of pressure adjustment controlled by the microcontroller.更多还原
