    摘要: A method of forming an Al—Zn—Si—Mg alloy coating on a strip that includes dipping strip into a bath of molten Al—Zn—Si—Mg alloy and forming a coating of the alloy on the strip, with the Al—Zn—Si—Mg alloy containing in % by weight: Al: 2 to 19%, Si: 0.1 to 2%, Mg: 1 to 10%, and Zn: 80 to 97%, and with the bath having a molten metal layer and a top dross layer on the metal layer, and the method including providing Ca in the composition of the bath to minimise the top dross layer in the molten bath.
