摘要： 采用了超声场来处理GW103K镁合金熔体,考察了超声功率和超声处理温度对镁合金熔体净化效果的影响.研究结果表明:熔体净化程度与超声施加功率和熔体温度有关,温度太低和功率太大都不利于超声净化.在本实验条件下:680℃时,超声功率200W,处理时间60s净化效果比较明显;710和730℃时,超声功率160W,处理时间60s净化效果比较好.铸锭中夹杂物越多电导率越小,电导率可以表征铸锭的净化程度.

Abstract: Research was conducted on the effects of varying power and treatment temperature on molten GW103K magnesium purification by ultrasound. Low temperature and high power levels both adversely affected ultrasonic purification efficiency. An ultrasonic power of 200 W for 60 sec at a temperature of 680°C provided good purification. Ultrasonic power of 160 W for 60 sec at either 710 or 730°C provided even better purification. Conductivity decreased as ingot inclusions increased and can be used as an indicator of the level of ingot purification.
