System Solutions for Metals Processing

As mill speeds continue to increase, the power and complexity of conventional blow-off and coating control methods also changes.  ACI Air Knives eliminate the need for high volume compressed air, large blowers and heaters in most applications.

The Air Knives are applied to many of the leading manufacturers of aluminium, steel, and other types of metal production facilities to minimize downtime.

During the manufacturing process of steel strip, for example, scale has to be removed from the product’s surface before it passes through the rolling presses. To achieve this de-scaling, the strip has to pass through an acid ‘pickling’ bath. The acid is normally neutralised by passing the strip through a simple ‘washing’ bath and it is here where an air knife system is employed.
