A few days ago, evaluation results of the 15th China Patent Award were announced, and《A type of oriented silicon steel and its production methods and devices》,《A kind of flexible strip processing line suitable for producing various high strength steels》and《Cold-rolled enamelled steels with excellent fish-scaling resistance and extra deep drawing and its manufacturing methods》of Baosteel won the award of outstanding patent prizes.
This year, according to the regulation of《Awarding Methods of China Patent Prizes》, cooperating with different Local Intellectual Property Offices, relevant Departments and Units of State Council, related National Industry Associations and the recommendation from academician of Chinese Academy of Sciences and academician of Chinese Academy of Engineering, experts in the organization of China patent award evaluation committee selected and generated the 15th China patent awards.
The high magnetic induction oriented silicon steel produced by Baosteel self-developed invention patent of 《A type of oriented silicon steel and its production methods and devices》changed the passive situation that Chinese ultra high voltage transformer and efficient transformer had a long-term dependence on imported oriented silicon steels. Through the evaluation of some authorized experts from Three Gorges Office of State Council, China Machinery Industry Federation and National Energy Administration, the quality of physical products reached the advanced international level which had been successfully applied in the Three Gorges underground power station, Gezhouba and Shanghai direct current renovation projects and other major national projects.
Baosteel's pioneering《A kind of flexible strip processing line suitable for producing various high strength steels》had the characteristics of multifunction and various varieties, which can get a variety of high strength steel products through hot dipping, ordinary cold-rolling and electroplating with minimum investments. This invention patent filled the blanks at both home and abroad, made the situation of long-term dependence on imported advanced high strength steels to an end, played an significant role in promoting lightweight automobiles, reducing emissions, improving safety performance and stimulating the upgrade of Chinese iron and steel products, and generated good social and economic benefits.
The invention patent,《Cold-rolled enamelled steels with excellent fish-scaling resistance and extra deep drawing and its manufacturing methods》, took a full consideration of the matching relation between formability of steel sheet and fish-scaling resistance as well as the creative nitrogen control technology during the composition design process, and firstly developed enamelled steels with relatively lower costs and better comprehensive performance. The products filled the domestic blanks, which had been widely applied in several industries like light industry, home appliances, architectural decoration and environmental protection, and had been sold to Europe, America, Africa, Oceania and Southeast Asia.
