general-purpose air nozzles for <span style=\"font-weight:bold;font-size: 1rem\">edge wiping to remove water from the edges of steel sheets<\/span> in the surface treatment process after cold rolling.<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">\nHowever, the nozzles were fixed in place to target the edges of steel sheets of a specific width. This became problematic when the width of the supplied sheets changed. For example, when narrower sheets were fed through, the nozzles aimed at the outside edges of the sheet, causing the <span style=\"font-weight:bold;font-size: 1rem\">air to miss the edges and resulting in insufficient water removal<\/span>.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2025\/03\/noz-tf-long-custom-steel-main-PC.jpg\" alt=\"\" width=\"1200\" height=\"655\" class=\"alignleft size-full wp-image-5972\" \/><\/p>\n<p><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2025\/03\/noz-tf-long-custom-steel-image_02.png\" alt=\"\" width=\"1200\" height=\"655\" class=\"alignleft size-full wp-image-5972\" \/><\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">Insufficient water removal caused uneven plating color on the steel surface, while even minor defects left water stains.
