A new high in customer orientation is reached

The process of strip cleaning is similar to cleaning of any metal surface. Oil, grease, metal particles, dirt and soil all need to be removed. Each of the available cleaning processes have a combination of mechanical, electrical and chemical effects on metal surfaces involving temperature and time. Therefore, the most appropriate cleaning agents have to be selected keeping in mind its influence on lining materials and subsequent processes.

Electrolytic Cleaning involving the decomposition of water into hydrogen and oxygen is preferred by Tata Steel. During electrolysis, the development of gas, hydrogen and oxygen in this case, results in a mechanical effect which removes dirt or contaminations from the grooves and deepenings on the strip surface as well.
