Effect of Low Frequency Electromagnetic Field on Heat Transport of Hot-top Casting 6063 Aluminum Alloy
A low frequency electromagnetic field was applied during the hot-top casting of 6063 aluminum alloy process. Thermocouples (type K) were introduced into the metal to study the temperature profile in the ingot after a steady-state was reached. Two thermocouples were placed into the graphite ring to study the effect of low frequency electromagnetic field on the temperature of graphite ring. The experimental results show that under the effect of the low frequency electromagnetic filed, the heat transport between the melt and the mold is intensified; the length of contact zone with graphite ring decreases, the temperature profile of the ingot is modified during the low frequency electromagnetic casting process.
