At present, it is the fourth smart factory of SHBG Silicon Steel Technology Corporation, the world's most advanced production base of oriented silicon steel products. Here, we can fully feel the surging power of smart manufacturing of "future steel mills".
The Fourth Smart Factory mainly produces ultra-thin top grade oriented silicon steel. At present, it has achieved the global debut of a variety of high-grade oriented silicon steel.
In 2018, the "development and application of ultra-low loss oriented silicon steel for ultra-high voltage and high energy efficiency power transmission and transformation equipment" developed by the company won the second prize of the "China National Science and Technology Progress Award".
High grade oriented silicon steel products have been used in China's large UHV DC projects such as Changji Guquan ± 1100kV and Baihetan Jiangsu ± 800kV, which strongly support the construction of national key projects and completely replace imported oriented silicon steel.
In 2022 alone, SHBG will release six "global first products" representing the world's highest technology level: non oriented silicon steel for electric vehicles
At present, it has formed six series of 29 brands, including ordinary (AV), high efficiency (AHV), high magnetic induction (APV), high efficiency and high intensity (AHV-M), high intensity stress relief annealing (AHVR) and high intensity (AHS), covering 0.15 mm~0.35 mm and other specifications in an all-round way, and the actual material quantity of the products has reached the international advanced level.
Through independent research and development, the company has solved the worldwide problem of mutual restriction of high-frequency iron loss, magnetic induction and mechanical strength of non oriented silicon steel for electric vehicles, and built a complete manufacturing process system of non oriented silicon steel for new energy vehicles.
The very low S control, very low Ti control, harmful inclusion control, high Si and high Al content continuous casting control of steelmaking have been broken;
The key rolling technologies, such as rolling capacity limitation of strip width to thickness ratio and control of small hot rolling crown, are overcome;
The normalization and high efficiency of silicon steel process, cold rolling and anti breaking, rapid heating and annealing, texture optimization control, high precision coating and other industrial technical problems.
The green environmental protection coatings have been developed and three sub categories of green environmental protection coatings have been formed.
The application technology system of high-performance silicon steel for driving motor of new energy vehicles has been established in China. The user's technical support platform, product performance database, electromagnetic software simulation platform, core sample production and testing platform, and the material selection solution for driving motor silicon steel sheets have been established.
As the only national "silicon steel engineering technology research center" in China, SHBG undertakes the national mission of researching and developing high-grade silicon steel materials.
As a steel enterprise responsible for national science and technology research and development projects in the field of non oriented silicon steel for electric vehicles, the company has undertaken and participated in three national "863" projects and two national key projects, including "research and development of large-scale industrialization technology for high performance price ratio permanent magnet drive motors and their control systems for vehicles", "development and application of high efficiency, low loss and special purpose silicon steel". The national project in charge was rated as an excellent project by the Ministry of Science and Technology of the People's Republic of China, and the achievements of the project "Innovation and Application Technology Development of High end Silicon Steel Products for New Energy Vehicles" were rated as an international leading level
At present, it has 59 authorized invention patents, and is responsible for formulating one national industrial plan and one group standard; The global market share is as high as 25%, and the Chinese market share is more than 45%.
Among the new products released in 2021
The lowest loss of 0.18mm grade 060 oriented silicon steel products in the world.
Heat resistant scored oriented silicon steel is an ideal material for new type of energy-saving transformer with coiled iron core. The company invented a new type of heat resistant scored technology, which was successfully industrialized and launched globally in December 2020, ending the history of China's lack of manufacturing technology for heat resistant scored oriented silicon steel, which severely restricted the development of high-efficient three-dimensional coiled iron core transformers, marking that SHBG oriented silicon steel covers all the commercial products of oriented silicon steel in the world today.
The heat-resistant scored products of oriented silicon steel have achieved the overall leadership in the production technology of oriented silicon steel. It is estimated that the SHBG thin gauge ultra-low loss oriented silicon steel is used to manufacture a new class I energy efficiency transformer to replace the current transformers in China
Thin gauge high grade low temperature oriented silicon steel…
