Abstract: A mathematical model of electrical data calculation of coreless induction furnace is proposed and a useful method of measuring stray loss and electrical resistivity at high temperature of crucible is given. The determined data prove that the equifinal reactance error of furnace calculated by this method is less than 5％.
