摘要： There are provided an electromagnetic wiping device, a plated steel sheet wiping apparatus including the electromagnetic wiping device, and a method for manufacturing a plated steel sheet. A portion of a plating layer of a steel sheet having passed through a plating bath is preliminarily removed at least in an edge region of the steel sheet, and a gas wiping operation is performed. Therefore, overplating is prevented at least in the edge region of the steel sheet. In addition, since the load of gas wiping can be reduced while maintaining the line speed of the steel sheet, the quantity of scattered particles and the formation of dross can be reduced for improving the plating quality of the steel sheet and the productivity of a manufacturing process.

摘要： A gas wiping nozzle includes a primary nozzle portion and at least one secondary nozzle portion provided either or both above and below the primary nozzle portion. The secondary nozzle portion jets a gas in a direction tilted from the direction in which the primary nozzle portion jets the gas and at a lower flow rate. The gas wiping nozzle has a tip whose lower surface forms an angle of 60° or more with the steel strip. The gas jetting port of the secondary nozzle portion is displaced in the direction opposite to the steel strip at least 5 mm apart from the gas jetting port of the primary nozzle portion, and the secondary nozzle portion jets the gas so that the flow rate of the secondary gas jet comes to 10 m/s or more at the confluence with the primary gas jet from the primary nozzle portion.

摘要： A coating control system is provided enabling continuous operations, free of interruption for coating control purposes, while achieving desired coating weight and thickness profile for the various gages, widths and coating specifications encountered on a given continuous strip production line. In each of a pair of elongated pneumatic dies, a pressurized gas jet is controllably shaped and directed by flow-control means internally-mounted of each pneumatic die to impinge against its respective substrate coated surface with its major directional component of force being controlled to be perpendicularly transverse to the travel path of the coated strip across its full width. Adjustment of such internally-mounted means is coordinated with control of gas pressure supply and/or adjustment of die positioning means to maintain desired coating weight and coating profile across the width of the strip. Pneumatic and other crown-control measures of the invention are exercised along the centerline of the strip enabling production of continuous-strip galvanized steel product having improved tracking and handling properties.

摘要： A continuous dip-plating apparatus for a steel strip has a pot containing a metal melt which forms a plating bath, a device for causing the steel strip to run through the plating bath such that the steel strip makes a turn around a sink roll in the plating bath so as to be pulled upwardly above the surface of the plating bath, and a wiping device disposed above the pot and adapted for adjusting the amount of deposition of the metal melt to the steel strip. The apparatus further has a pair of flow regulating plates for suppressing deposition of dross to the steel strip. The flow regulating plates are arranged in parallel with and in the vicinity of the portion of the steel strip running upwardly through the plating bath with the upper ends of the flow regulating plates being disposed substantially at the same level as the plating bath. Preferably, the height of the portion of each flow regulating plate below the level of the surface of the plating bath is not smaller than 50 mm, while the distance between each flow regulating plate and the steel strip is preferably not greater than 80 mm. It is also preferred that the upper end of each flow regulating plate is positioned between a level which is 10 mm below the surface of the plating bath and a level which is 50 mm above the surface of the plating bath.
