Baoshan Iron and Steel Yupo "Ice" made icebreaker board
Time:
2010/2/1
China plans to build polar research ships, in order to enhance Chinas ability to bring the construction of icebreakers an opportunity. This also means that in order to create high-quality steel for the country to provide strong support for the development of various undertakings of the Baoshan Iron and Steel in turn usher in a new development opportunity.
State Oceanic Administration announced: Chinas first self-built icebreaker fleet plans to be completed this year, established the project began construction in 2011, 2013 and put into use. After the completion of this icebreaker Polar expedition with the present, Chinas use of "Snow Dragon" was formed, together with the ice survey operations and environmental and resource capacity icebreaker fleet. Now well-known "Snow Dragon" number, is introduced from Ukraine in 1993. But "Snow Dragon" was an ice-breaking capacity is limited, comprehensive level of technical equipment with the advanced world there is still a certain gap between the icebreaker, with a self-built icebreaker, is Chinas polar expedition staff dream.
To build your own icebreaker, ship plate is the most critical elements. According to introduction, icebreaker bow case with at least 5 cm thick steel plate is made of steel-intensive components used inside the support of the hull waterline area of the steel reinforcement with anti-collision. The plate must have a strong anti-low temperature toughness, crack resistance and high strength and excellent weldability, in order to ensure that the polar temperature of minus 40 ℃ below to carry out operations and navigation. Over the years, ship manufacturing and ship plate manufactured by the technical limitations, our country has not the capacity to conduct the independent construction of icebreakers.
Experts believe that the ship plate in terms of the overall manufacturing level, Baosteel already has a manufacturing capacity of icebreakers needed to supply steel plates, it is important to grasp the elements in the design and the purity of molten steel. The current technical difficulties are not the steel base material, but rather supporting the welding technology, including related consumables for synchronous development. If you have participated in the construction of our own possibility of icebreakers, Baosteel and welding consumables industry can work together to create advanced materials.
