air knife for steel strip galvanizing line

Qingdao Hexin produces various structural forms of hot-dip galvanizing air knives for strip steel, which are used in continuous strip steel hot-dip galvanizing production lines.

 

On the basis of the original air knife, a large number of improved designs have been made to derive different structural forms of air knives. By applying the laminar flow effect of multi-point and multi cavity air knife jet airflow, our air knife has excellent equipment performance and is matched with units with a linear speed of 90-200 meters/minute. The control range of hot-dip galvanized coating is 30-275 grams/square meter, and the control range of hot-dip aluminum zinc silicon coating is 20-200 grams/square meter.

 

Its advantage is that the amount of zinc on the board surface is uniform and consistent, with a dispersion of less than ± 2% between the left, middle, right, and three points.

 

The company adopts advanced processing methods and strict production management methods, which enables the air knife to strive for excellence in processing accuracy. It has been recognized and praised by multiple steel mills for its use.

 

With the increasing demand for home appliance boards and high-end automotive sheet materials, the requirements for galvanized strip steel for air knife equipment have also greatly increased. The main technical requirement is to achieve automatic control of coating thickness. Our company has conducted research and analysis on multiple devices, and has developed our own products based on their advantages and disadvantages to meet market demand and improve the level of domestic equipment manufacturing industry.
