脉冲磁致液面振荡作用下测量熔体热历史曲线的装置
摘要：
本发明涉及一种脉冲磁致液面振荡作用下测量熔体热历史曲线的装置，属材料加工技术领域。本发明所述装置主要由脉冲电源、蚊香形感应线圈、电热丝、升降杆、陶瓷管和插头组成；电热丝经插头连接220V交流电，蚊香形感应线圈连接脉冲电源，升降杆上放置盛有金属块的铸型；首先电热丝发热使金属块熔化；之后升降杆上升，铸型靠近蚊香形感应线圈，蚊香形感应线圈对金属熔体施加脉冲磁致液面振荡处理；热电偶插入熔体中并固定，测得熔体热历史曲线。相比传统测温方法，本发明省去了浇注过程，能更加稳定、准确地测得熔体热历史曲线，为获得脉冲磁致液面振荡细化金属凝固组织的提供可靠的温度数据。
摘要（英）：

The invention relates to a device for measuring a melt heat history curve under action of pulse magnetic liquid level oscillation, and belongs to the technical field of material machining. The device is mainly composed of a pulse power supply, a mosquito-repellent incense type induction coil, an electric heating wire, a lifting rod, a ceramic tube and a plug, wherein the electric heating wire is connected with a 220V alternating current through the plug, the mosquito-repellent incense type induction coil is connected with the pulse power supply, and a casting mold containing a metal block is placed on the lifting rod. Firstly, the electric heating wire heats to melt the metal block, then, the lifting rod ascends, the casting mold is close to the mosquito-repellent incense type induction coil, the mosquito-repellent incense type induction coil exerts pulse magnetic liquid level oscillation processing on the metal melt, a thermoelectric coupler is inserted into the melt and is fixed, and the melt heat history curve is measured. Compared with a traditional temperature measuring method, the casting process is removed, the melt heat history curve can be more stably and accurately measured, and the reliable temperature data are provided for obtaining a pulse magnetic liquid level oscillation refined metal solidification structure.
