ABSTRACT:
A support plate is used, together with the shell of a vessel for the holding and/or refining of aluminum, in combination with a refractory sheet and a metal heating element container positioned in a graphite block to protect said heating element and to thus extend the life of said heating element. Oxidation of the graphite block is precluded, as is the attack upon the heating element by chlorides passing through the pores of said graphite block.
