[0002] With the market expansion of high value-added products such as cold-rolled high-end home appliance plates and automobile outer plates, and the product development of zinc-aluminum-magnesium, aluminum-silicon-coated and high-strength hot-dip galvanized strip, the quality characteristics of the zinc pot air knife of the hot-dip galvanizing unit under high temperature and complex environment have become one of the key bottleneck factors limiting the unit's operating stability and product quality improvement.

[0003] During the production of automobile outer panels, the turbulent airflow at the edge of the strip causes zinc liquid or foreign matter to splash and adhere to the air knife lip, resulting in air knife streak defects on the strip surface. There is no obvious regularity in the location of the defects, and there are differences between different coatings, which seriously affects the quality of the outer panels and prevents the outer panels from being produced normally.

[0004] The traditional cleaning air knife structure only has a polished L-shaped thin blade welded on the top of a straight rod. The air knife can only perform cleaning operations perpendicular to the blade lip, which has great limitations and cannot clean the streaks in the middle of the strip. Utility Model Content
