Its function is to form an airflow like a knife after the compressed high-pressure gas passes through the gap of the air knife, and spray it onto the steel strip to scrape off the excess zinc liquid on the surface of the steel strip coming out of the zinc pot and flow it back to the zinc pot.
The design and manufacturing quality of the air knife nozzle lip directly affect the uniformity and flatness of the galvanized layer, as well as the thickness control of the zinc layer.
Characteristics:
• Good wear resistance: The lip needs to be in contact with high-speed airflow and zinc liquid for a long time, so it needs to have good wear resistance to extend the service life.
• Precise size and shape: The size and shape of the lip need to be precisely controlled to ensure the stability and uniformity of the airflow, thereby ensuring the galvanizing quality.
• Good high temperature resistance: The lip needs to work in a high-temperature environment, so it needs to have good high temperature resistance to prevent deformation and damage.
• Easy to maintain and replace: The lip needs to be inspected and maintained regularly, so it needs to be easy to disassemble and replace to improve production efficiency.
In order to meet these requirements, the hot-dip galvanizing air knife nozzle lip usually adopts special materials and manufacturing processes, such as using wear-resistant alloy materials and performing surface treatment. At the same time, in the process of use, it is also necessary to pay attention to the maintenance and care of the lip, regularly check the wear situation of the lip, and replace the severely worn lip in time.
