A method of producing aluminum-clad steel has been developed which involves roll-bonding the aluminum sheet to the hot-dip aluminum-coated steel. The steel substrate in the hot-dip aluminum-coated sheet is low carbon rimmed steel with nitrogen addition. Aluminum-clad steel sheets with various cladding thicknesses of 350mm-wide have been produced by a test cladding mill, which consisted of a remodeled four-high reversing mill with 200mm-diameter work rolls, high frequency induction heating equipment, and three pay-off reels. The mechanical properties of the sheets, the microstructures of the interface, the adhesion of the coating layer, and the formability of the aluminum-clad steel have been investigated. A brief discussion is given on the mechanical properties of the product.
