Abstract
An improved electric induction furnace for use in the continuous heat treatment of a running length of coated metal strip moving in a substantially straight path through the furnace includes at least one heating coil extending completely around the path of the strip and extending in closely spaced relation to the opposed surfaces of the strip. The furnace is mounted on a track for movement transversely of the strip path, and each coil is provided with movable connector doors for opening and closing the continuous loops whereby when the coil is not energized, the connector doors may be disengaged to open the coil and permit the furnace to be moved along its track between a retracted non-use position and an online heat treating position. The coils are supported for transverse and angular adjustment to accurately align the coils with the strip whereby the opposed surfaces of the strip are substantially equal distant from the heating coils throughout the path through the furnace.
