OREANDA-NEWS. September 13, 2011. A batch of high-strength thin container steel with strength of 800MPa and thickness of 1.2mm has been successfully trial-produced at compact strip production (CSP) plant, an arm of Wisco steel bar plant, and the sample has also reached customer. It shows that Wisco strides a great step towards light weight steel, reported the press-centre of Wisco.

In line with demands for industries transformation and upgrading, some industries including construction, automobile, home appliance, container, engineering and machinery proposed a common goal of saving steel in Twelfth Five-year Program, which means steel should be featured as high-strength, corrosion resistant, light weight, long life and recyclability.

At present, Wisco possesses the capability for batch production of high-strength thin container steel, ready to supply downstream customers with material of higher strength, thinner thickness and energy saving during transportation. Several years ago, CSP realized the trend of light weight for steel, and aimed at it to carry out a serial of technical breakthrough. Based on dozens of years of hot rolling operation experience integrated with processes, technologies as well as products kinds, technicists consulted mass information plus repeated calculating and experimenting, bold in innovation on design paper by equipment supplier SMS.

They attempted to surpass their own existing technologies by means of foreign equipments and technologies. After repeated commissioning, technicists conducted autonomous integration on CSP continuous casting tandem rolling process and equipments operation, enabled product’s limitation dimension exceeding original design via both improving heating efficiency for soaking pit and optimizing function, power and configuration for rolling mill. Compared to products made by Japan Nippon, German ThyssenKrupp and Sweden SAAB, products made by CSP are thinner and lighter with the same strength, reputed as “Wisco exclusively made”.

Reportedly, in stead of thick, heavy and low strength traditional steel, high-strength thin container steel can not only reduce container weight by 20%, but also save transportation cost around 17% for enterprise.
