OREANDA-NEWS. April 12, 2013. TISCO’s heavily coated M310-50A silicon steel was used in the 4 power units of the first phase of Hongyanhe Nuclear Power Project in Liaoning. Among the 4 power units, No.1 power unit has combined to the grid.
 
In order to solve the restraints for the new silicon steel materials required by the million kilowatts class nuclear power generator in China and promote their localization, TISCO developed the technological process for C6 heavily coated silicon steel, solved the technical problems such as the “bright spot” on the surface, the coating-easily-come-off, the uneven coating thickness and low adhesiveness and have mastered the key process technologies and control points for production of heavily coated silicon steel. The mass production and delivery of the heavily coated silicon steel for high-rating power generator is realized.
 
The heavily coated silicon steel is used in nuclear power projects. TISCO is the first and the only producer in China to produce this product for the nuclear power industry. Till now, the silicon steel required by the power units of the nuclear power projects under construction in China—Ningde nuclear power project, Fuqing nuclear power project and Taishan nuclear power project—are supplied by TISCO.
