The Edge Wipe: Advanced Aluminum Strip Coolant Removal

The Edge Wipe is a state-of-the-art solution to the ongoing challenge of removing aluminum strip coolant during the rolling process. Industry experts understand that coolant beads on strip edges can cause coil staining, environmental contamination, and higher coolant consumption. The Edge Wipe system effectively mitigates these problems, ensuring optimal dryness of strip edges and improving overall production efficiency.

The Edge Wipe technology integrates seamlessly with conventional mill strip drying equipment to provide superior control over strip edge dryness. This system is essential for preventing the migration of coolant edge beads, which can lead to significant quality issues such as strip staining.

The Edge Wipe efficiently removes coolant beads from the strip edges by employing blow-off jets and suction ducts, ensuring a cleaner and more efficient rolling process. Strip position senors actively track the edges during rolling, guaranteeing the air jets are always optimally positioned. The system's design includes multi-nozzle air sweeper jets that clear the underside of the strip and targeted knock-off jets to remove the coolant at the strip edges. This comprehensive approach ensures that unwanted coolant is directed away from the strip, significantly reducing contamination and improving strip quality.

The Edge Wipe's stainless steel construction and integrated PLC control make it durable and user-friendly. Diagnostics and alarm status displays make monitoring easy. The Edge Wipe system is particularly beneficial for mill operators, maintenance engineers, and quality control specialists within an aluminum plant. It is utilized in aluminum cold mills, where maintaining strip edge dryness is crucial for product quality. Incorporating the Edge Wipe into the rolling process addresses the critical challenge of aluminum strip coolant removal, ensures compliance with environmental regulations, and enhances overall production efficiency.

Benefits of the Edge Wipe System

• Efficient coolant removal: The Edge Wipe system reduces edge bead contamination by up to 80%, ensuring cleaner coils and reduced staining.
• Automatic adjustment: the system automatically adjusts to varying strip widths and positions, optimizing the air jets for maximum edge-bead removal.
• Environmental impact: The Edge Wipe enhances the mill's environmental performance by containing the coolant within the mill sump area.
• Cost savings: significant savings are realized through reduced coolant consumption and decreased downstream rectification work, contributing to a more sustainable operation.
• Modular design: The robust, modular construction allows easy maintenance and integration into existing or new mill installations.
• Improved yield and quality: by enhancing strip edge dryness, the Edge Wipe improves yield, quality, and performance of the production process, reducing coil telescoping and increasing productivity.
