More process reliability in the hot-dip galvanizing process

eWIPE greatly simplifies and automates the process of cleaning the air knife gap. Maintenance costs are noticeably reduced and the risk of accidents to operators is minimized. By means of continuous cleaning during operation there are fewer surface defects. In this way eWIPE promotes a consistently high zinc coating quality. This results in less waste and fewer downgraded coils, which reduces overall costs. The system can be retrofitted to many types of air knives.

The eWIPE Air Knife WIPing Equipment is a pneumatically operated cleaning tool for air knives in galvanizing lines. It allows the removal of firmly bonded zinc deposits inside and outside the nozzle lips.

The system mainly consists of:

• two cleaning devices including a pneumatic cylinder for mounting on a stable substructure upon each air knife
• two connector bars for quick connection of the pneumatic and electrical lines
• one stand with the pneumatic control system
• one small electric control cabinet for the electronic control system
