The lines include powerful floatation ovens serving for contact-free and efficient strip drying on the one hand and to polymerize the coating on the other. The ovens are characterized by a consistent heating and cooling performance. State-of-the-art burner technology and control systems make operation very efficient. As the strip is guided through the heating and cooling section on a progressive air cushion, mechanical strip contact is prevented which keeps the surface free from defects. The ovens are of modular design and supplied to the customer in pre-assembled condition. The entire thermal process is controlled via a model that presets the treatment curve and the reference parameters and thus ensures high process reliability and product quality. The model has a comprehensive database and its own software. It can be integrated inline in the level-2 automation system, but also be connected offline.
