Castellanza, January 11, 2021 – Tenova, a leading company specialized in innovative solutions for the metals and mining industries, has been contracted for a 200,000 ton/year new high-speed electrolytic tinning line with insoluble anodes by Perusahaan Sadur Timah Malaysia (PERSTIMA) Berhad, premier producer and supplier of high quality tinplate in South East Asia. This cutting-edge technology will be implemented in PERSTIMA’s plant in Batangas (Philippines).
The electrolytic combined tin-plating and tin-free steel line will work at 550 meters/minute at entry/exit and 420 at the process section, for annual production of 200,000 tons. The steel strip will be 550-1000 mm wide and 0.10-0.60 mm thick, and the line will process all the main grades of steel for a product mix which will satisfy the most recent demand of the high-quality market. A minimum tin coating thickness of 1.1 g/m2 is guaranteed.
The line is equipped with a dedicated section (cells and recirculation equipment) for the production of tin free steel process as well. Tenova will provide the state-of-the art automation with an enhanced Web-Based Level 2 and Roll Management Software to automatically schedule roll activities in the processing line.
Finally, a further improvement in the quality of the tin-plate has been achieved through the development of special edge-masks. These devices prevent the “white edge defects” due to tin overcoating at the edges while processing strips with different widths. In addition, Tenova edge-mask design guarantees easy inspection and access to the cell.
Tenova Insoluble Anode Technology with IGBT Rectifiers globally permits a large operating saving in tin and electrical consumption, guaranteeing the top of quality. The electrolytic line is expected to be put into operation by Q4-2021.
