Recently, Baosteel 1420 tin production line celebrates its 15th anniversary. Today, with first ranking in domestic market share and wide approval by overseas users, Baosteel 1420 tinned products prove to the world that Baosteel is equipped with the world's advanced tin plate manufacturing capacity.
In 1998, Baosteel 1420 tin production line produces steel can tin-plate for the first time and the history that China's metallurgical industry could not produce tinned premium products ends. Baosteel has also become the first domestic steel enterprise which produces high-quality tin plate. In 1999, 1420 tin production line successfully developed K board, which ended China's long-term dependence on high corrosion food can tin plate foreign imports. In 2001, 1420 tin production line succeeded in trial of color TV picture tube ultra-thin steel sheet shadow mask steel strip (BAK), which filled domestic blank and significantly improved the competitive advantage of China's color TV industry chain. From beverage can material, television picture tube shadow mask strip, for 15 years, 1420 tin production line continues to raise tin plate production capacity and tin plate becomes an essential element in people's daily life.
In recent years, to further improve Baosteel tinplate product profitability, meet downstream users' needs in cost control and energy saving and environmental protection, 1420 tin production line speeds up innovation and makes efforts in high added value product expansion in getting thinner and more environmental friendly under the support of tin plate production, sales and research team.
To continue to promote Baosteel tin plate width widening and thinning, 1420 tin production line makes efforts in unit roll system optimization and transition switching and gradually masters high-speed annealing line stable through-the-board technology. To solve the problem of tin plate accuracy control, 1420 tin production line solves a series of process problems through process optimization and equipment modification. In response to the market impact brought by plastic and aluminum can diversified packaging material, 1420 tin production line practices hard skill in cost control and through upper and lower process collaboration, achieves tin plate comprehensive yield rate yearly increase. Currently, steel can tin-plate thinning work has made results. Over the years product thickness reduces by nearly 24% per and per ton steel canning raises by nearly 50%. In 2011, 1420 tin production line enters high-end milk can market. Meanwhile 1420 tin production line actively expands to application market high-end electronic product field. With tinned production, marketing and research integration as the basis, it successfully develops high profit tinned varieties and provides basis for downstream user raw material localization and cost reduction.
During 15 years of development, Baosteel 1420 tin production line always adheres to "thin, green, environmental friendly" development concept, connects market demand and technological innovation, walks out a green, energy saving and emission reduction independent innovation road and provides strong support for Baosteel tin plate product market competitiveness continuous improvement.
