Publication number: 20240158891Abstract: A hot dip method of forming an Al—Zn—Si—Mg alloy coating on a strip is disclosed. The method includes controlling the conditions in the molten bath to minimise the top dross layer in the molten bath. In particular, the method includes controlling top dross formation by including Ca and/or Sr in the coating alloy in the bath.Type: ApplicationFiled: October 18, 2023Publication date: May 16, 2024Applicant: Bluescope Steel LimitedInventors: Michael Angel LOPEZ, Wayne Andrew RENSHAW, Andrew Vincent MICALLEF, Nega SETARGEW, Paul DONALDSON

Publication number: 20240141471Abstract: A method of forming an Al—Zn—Si—Mg alloy coating on a steel strip includes 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. The method also includes controlling conditions in the molten coating bath and downstream of the coating bath so that there is a uniform Al/Zn ratio across the surface of the coating formed on the steel strip. An Al—Zn—Mg—Si coated steel strip includes a uniform Al/Zn ratio on the surface or the outermost 1-2 ?m of the Al—Zn—Si—Mg alloy coating.Type: ApplicationFiled: November 3, 2023Publication date: May 2, 2024Applicants: Bluescope Steel Limited, Nippon Steel Corporation, Nippon Steel Coated Sheet CorporationInventors: Wayne Andrew RENSHAW, Cat TU, Joe WILLIAMS, Jason HODGES, Shiro FUJII, Nobuyuki SHIMODA, Shuichi KONDO, Takashi HIRASAWA

Publication number: 20230304122Abstract: 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 pH 5-9. Particular embodiments focus on Al—Zn—Si—Mg alloys that contain the following elements in % by weight: Zn: 2 to 19, Si: 0.01 to 2, Mg: 1 to 10, and Balance Al and unavoidable impurities.Type: ApplicationFiled: February 24, 2023Publication date: September 28, 2023Inventors: Wayne Andrew Renshaw, Aaron Kiffer Neufeld, Ross McDowall Smith, Geoff Tapsell
