China plans to build polar scientific research ship, to enhance the ability of China's construction of icebreakers provide a turning point.

This also means that the build quality steel for the country to provide strong support for the development of Baosteel will usher in new opportunities for development. State Oceanic Administration announced: China's first self-built icebreaker fleet plans to complete the project this year, begin construction in 2011,
2013. Upon completion, this icebreaker Polar expedition with the current use of the "Snow Dragon" operations with the formation of ice and environmental and resource survey of the icebreaker fleet capacity. Now well-known "Snow Dragon", is introduced from Ukraine in 1993. But the "Snow Dragon" ice-breaking capacity is limited, integrated with the world advanced technology and equipment is still a certain gap between the icebreaker, with a self-built icebreaker, is the dream of polar expedition staff. To create your own icebreaker, ship plate is one of the most critical elements. It is reported that icebreaker bow case with at least 5 cm thick steel plates, steel members which support use of intensive, part of the waterline the hull with anti-collision steel reinforcement. These plates must have a strong resistance to low temperature toughness, crack resistance and high strength and excellent weldability, in order to ensure the polar temperatures below minus 40 ℃ to carry out operations and navigation. Over the years, by the shipbuilding and ship plate manufacturing technology limitations, China has no independent capacity to conduct the construction of icebreakers. Experts believe that the overall level of manufacturing to Ship, the Baosteel already has a plate supply capacity required for manufacturing ice-breakers, it is important to grasp the elements of design and purity of the molten steel. The technical difficulties are not present steel base metal, but rather supporting the welding technology, including related consumables for synchronous development. If you have participated in the possibility of self-construction of icebreakers, Baosteel and welding industry can work together to create advanced materials.
