Abstract:
A method of forming a coating of an Al—Zn—Si—Mg alloy on a steel strip to form an Al—Zn—Mg—Si coated steel strip is disclosed. The method includes the steps of dipping steel strip into a bath of molten Al—Zn—Si—Mg alloy and forming a coating of the alloy on exposed surfaces of the steel strip and cooling the coated strip with cooling water. The cooling step includes controlling the pH of cooling water to be in a range of p H 5-9. Particular embodiments focus on Al—Zn—Si—Mg alloys that contain the following elements in % by weight: Zn: 30 to 60, Si: 0.3 to 3, Mg: 0.3 to 10, and Balance Al and unavoidable impurities.

Claim (Index 1):
A method of forming an Al\u2014Zn\u2014Si\u2014Mg alloy coating on a steel strip to form a coating of an Al\u2014Zn\u2014Mg\u2014Si on a steel strip, with the Al\u2014Zn\u2014Si\u2014Mg alloy including the following ranges in % by weight of the elements Al, Zn, Si, and Mg:\n Zn: 35 to 50% Si: 1.2 to 2.5% Mg: 1.0 to 3.0% Balance Al and unavoidable impurities, the method including the steps of dipping the steel strip into a bath of molten Al\u2014Zn\u2014Si\u2014Mg alloy and forming a coating of the alloy on exposed surfaces of the steel strip, cooling the coated strip with cooling water, conditioning the surface of the coated strip in a rolling section, and passivating the surface of the coated strip to provide resistance to wet storage and early dulling by coating the strip with a passivation solution in a passivation section, with the cooling step including controlling the pH of cooling water to be in a range of pH 5-9 by adding acid to the cooling water and controlling the temperature of cooling water to be in a range of 25-80\u00b0 C., and with the cooling step including a water quench step and (a) a closed loop in which water is circulated through a circuit that supplies water to the coated strip and collects and cools water and returns the cooled water for cooling the coated strip or (b) an open loop in which cooling water is supplied from a cooling tower to the coated strip and collected and recirculated through the cooling tower.
