Device for producing coated steel sheet and method for producing coated steel sheet

摘要

This device for producing a coated steel sheet is provided with: blow-off unit (11) that blows gas against excess coating material (9x) accumulated along the edge of a steel sheet (8) passing along in one direction, thus eliminating the excess coating material; and a coating material recovery unit (12) that recovers the excess coating material (9x) eliminated by the blow-off unit (11). The blow-off unit (11) has a blowing nozzle (11a) and a gas supply unit (11c). The coating material recovery unit (12) has a duct (12a) and a coating material housing vessel (12b). When viewing the duct (12a) in a plan view, the exit (12a2) thereof is disposed overlapping in a manner so as to fall within the opening (12b1) of the coating material housing vessel (12b), and moreover, when viewing the duct (12a) in a lateral view, a gap (12c) is provided between the opening (12b1) of the coating material housing vessel (12b) and the exit (12a2).
