The inductor had a copper water-cooled bushing fitted with a water-cooled joint cap, and was lined with a spinel bonded alumina refractory grain.
Yet the temperature in the refractory about the bushing did not exhibit any problems to continued operation.
One alternative in heading off the adverse thermal discontinuity due to the bushing joint insulator is water cooling the insulated joint in the bushing as shown in Fig.
