Abstract: PURPOSE:To prevent Al-concentration on the surface of a molten zinc plating layer to enhance the spot weldability of a molten zinc plated steel strip, by heating the molten zinc plated steel strip to a specific temp. after quenching the same by injecting water. CONSTITUTION:A steel strip is passed through a molten Zn-bath containing 0.07-0.17% of Al to adhere molten zinc to the surface thereof and the amount to be adhered of molten Zn is adjusted by injecting inert gas from a gas wiping nozzle 3. Succeedingly, the plated steel strip is cooled by spraying water or an aqueous solution containing various metal chlorides from a spray nozzle 41 thereto to solidify the plated layer while the Al-concentration in molten Zn adhered to the surface of the steel strip is prevented. In the next step, the treated steel strip is introduced into a heating furnace 5 having an atmosphere containing 1% or more of oxygen and water is sprinkled to the surface thereof or steam is blown into the furnace while held to 200-400 deg.C for 30sec or more to form thin Zn-oxide film on the surface of the Zn-plating layer and the resulting plated steel strip is wound up while cooled by a conditioning cooling furnace 6.
