ABSTRACT:
Concepts for producing thermal conditions, in strip material, conducive to directional recrystallization are disclosed. An inductively heated susceptor contains a slot and the susceptor shape develops a thermal condition where the edges of the strip are cooler than the center of the slot. The furnace includes a fluid cooled cold zone as well as the hot zone and can produce a steep longitudinal thermal gradient in the strip.
