Plant for the continuous heat treatment of steel strips or the like

摘要

Two unheated rolls (2, 3) are in an insulated nonmagnetic housing (1) which also accommodates a transformer core (7) with a secondary winding formed by a loop of the steel strip (4) undergoing heat treatment. The primary winding (10) of the transformer is outside the housing (1). The strip heated in the transformer is quenched by the fresh strip (4) fed to the roll (2), and by the roll itself.
