The R&D team of FDTS Carbon Materials Technology Corporation independently innovated the scientific research achievement "Carbon Fiber Dispersion Technology and Application in Graphite Electrode Paste", which broke the foreign technology monopoly and effectively improved the independent innovation capability of key preparation technology for graphite electrode joints in China. Recently, this research achievement won the special award for outstanding technological innovation.
The strength of the graphite electrode joint is an important indicator that affects the product qualification rate. The carbon fiber reinforced technology has been successfully applied to the production of graphite electrode joints abroad. German SGL Company applied for carbon fiber reinforced graphite electrode joint patents in Europe and China in 2004 and 2009 respectively. At present, this key technology is still under strict confidentiality at home and abroad.
In order to quickly solve the technical problem of uniformly dispersing chopped carbon fibers in graphite electrode paste, the FDTS technical research team has found another way to apply the dispersion technology of carbon fiber in graphite electrode paste to the production of graphite joints. And to achieve industrialization, compared with the current domestic traditional production process graphite electrode joints, the microstructure is significantly different. The φ331mm high-power joint prepared by carbon fiber + changing powder method has a flexural strength of 26MPa, which is better than the previous joints in terms of homogeneity and good index stability. It effectively improves the internal quality and competitiveness of the product and improves our country. The independent innovation ability of the key preparation technology of graphite electrode joints.
