Air-Knives and Integrated SolutionProducts
Industry-leading results for the selective application of zinc
or aluminium on continuously processed steel strip
DUMA-BANDZINK galvanizing and aluminising systems are characterized by outstanding coating results using a minimum of Zn/Al layers. Moreover, the equipment is robust in service and easy in maintenance and handling.
Our recent development is the integration of DUMA-BANDZINK JetPro Air-Knives and eMASS® strip stabilization of EMG Automation which successfully combines two market leading technologies for increasing the product and process quality in coating lines.
Industry leading results for the application of zinc or aluminum to continuous steel strips - coated with highest accuracy.
DUMA-BANDZINK galvanizing and aluminizing systems create outstanding coating results due to the characteristics of their Air-Knife Systems. The extremely robust design and finish follows the aim to guarantee a high overall stiffness of the system and minimizing vibrations.
A totally uniform pressure distribution over length of the Air-Knife lips and quick pressure regulation via the patented radial controller significantly improve the coating properties - especially in the long run. DUMA-BANDZINK Air-Knives are conceived in a modular design. And many efficiency-adding add-ons are available according to customer requirements. Moreover, DUMA-BANDZINK enables investment-effective solutions where needed and applicable.
Highlight: Integrated Solution
The integrated system of DUMA-BANDZINK Air-Knife + EMG Automation eMASS® Strip Stabilization System offers enhanced control of the wiping and coating process by using a closed loop control system, which is a model based coating weight control-system for optimal fine-tuning of the Air-Knife pressure control and positioning system. Due to its self-learning feature, it continuously optimizes the coating model during production to reach minimum coating weights and highest coating uniformity.
The Integrated Solution combines the best breeds from two world-leading technologies to the following benefits:
- Most accurate zinc coating results
- Very stable strip position and reduction of cross bow >60%
- Air-Knife to strip distance <7 mm
- Reduction in coating-weight deviation by factor 2
