Abstract
Method, system and apparatus for controllably heating copper alloy dam blocks in revolving edge dam chains in twinbelt continuous casters by induction heating of thermally-sprayed ferromagnetic layers bonded in shallow depressions in such blocks. High thermal conductivity of such blocks advantageously quickly conducts inductive heat from ferromagnetic layers into the blocks. For casting a slab of electrolytic anodes having aligned opposed protruding lugs, such chains include uniformly spaced lug-molding pocket blocks. Periodic induction heating of ferromagnetic layers on dam blocks of one chain or the other keeps pocket blocks aligned as revolving chains travel downstream along opposite sides of moving mold casting regions. Directly induction heating copper alloy dam blocks is very impractical. Therefore, ferromagnetic layers are thermally sprayed into depressions in blocks prior to assembling such chains. Pancake-type induction heaters inductively heat ferromagnetic layers of revolving dam blocks as they return toward a caster's entrance.
