Tenova to Supply Electrolytic Lines in China

02/05/2010 - Yi Chang Three Gorges Quan Tong Colored and Galvanized Plate Co. Ltd. has awarded contracts to Tenova for the supply of two high-speed Electrolytic Tinning Lines equipped with insoluble anodes technology and two high-speed Electrolytic Chromium Coating Lines.

Yi Chang Three Gorges Quan Tong Colored and Galvanized Plate Co. Ltd., China, has awarded to Tenova, Italy, contracts for the supply of two high-speed Electrolytic Tinning Lines equipped with insoluble anodes technology and two high-speed Electrolytic Chromium Coating Lines.
 
All four lines will process thin strip material for the packaging market. The process section will run as fast as 450 m/min with the entry and exit sections running at 600 m/min. The lines are designed for a strip 1250 mm wide and 0.14 to 0.55 mm thick.
 
The target annual production is 250,000 tonnes.
 
Each line includes two uncoilers, laser welding machine, side trimmer, vertical entry accumulator, cleaning and pickling sections, tension leveler, plating section vertical exit accumulator, inspection and flying shear with two recoilers.
 
The Chromium Coating Lines will employ what Tenova calls a state-of-the-art, two-step plating technology. The company says that this process allows for more precise and independent control of both the metallic chrome layer as well as the chrome oxide layer of the coating.
 
Based on a proprietary patent, the insoluble anodes technology is at the heart of the plating process of Tenova tinning lines. The technology is said to result in very low tin loss in the sludge (less than 4%) and other advantages such as cost savings, easier operating procedures, and higher operational safety.
 
Specially designed edge-masks from Tenova will be employed for improving the tinplate quality on the edges while allowing fast and easy inspection and access to the cell.
 
The first coils are expected to leave the production lines in mid-2011.
 
Tenova designs and supplies advanced technologies, products, and services for the metal and mining industries. The company operates through a network of 33 companies based on five continents.
