Description

Technical Field

[0001] The utility model relates to the technical field of hot-dip galvanizing air knife systems, in particular to a device for processing slag sticking on the edge of a hot-dip galvanized strip steel. Background Art

[0002] Hot-dip galvanizing air knife systems are crucial for ensuring the thickness and quality of the coating on the strip surface. The edge baffle is a key component for preventing strip edge defects. Precision adjustment of the edge baffle not only reduces strip edge quality defects but also reduces air knife operating noise. The original design incorporated a ceramic wheel on the edge baffle. This wheel, when in contact mode, maintains a calibrated distance between the strip and the edge baffle, enabling adjustments and process control for strip edge thickness or scratch defects, ultimately preventing production defects. During current production, unsolidified zinc liquid adheres to the ceramic wheel due to contact with the edge of the strip. When the liquid accumulates too much, the edge baffle will run unstably, resulting in uneven coating on the edge of the strip. At the same time, its unstable operation can easily cause slagging on the edge of the air knife, causing slight scratches on the edge of the strip and quality defects of the strip product. When the degree of slagging is severe, the strip will carry away excess zinc slag, causing frequent damage to the working roll surface of the skin-pass mill, which will not only cause product quality defects, but also increase cost consumption and affect the stability of the normal operation of the production line.
