FDTS Carbon's carbon research team independently innovated the scientific research result "Dispersion technology and application of carbon fiber in graphite electrode paste", breaking the foreign technology monopoly and effectively improving the independent innovation ability of the key manufacturing technology of graphite electrode joints in China. Recently, this scientific research achievement won the 12th Gansu Provincial Staff Excellent Technology Innovation Achievement Special Award.
The strength of the graphite electrode joint is an important index that affects the qualification rate of the product. Carbon fiber reinforced technology has been successfully applied to the production of graphite electrode joints abroad. The German company SGL has 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 strictly confidential at home and abroad.
In order to quickly solve the technical problem of uniformly dispersing chopped carbon fibers in graphite electrode pastes, FDTS Carbon Technology Co., Ltd. opened a new path and applied the dispersion technology of carbon fibers in graphite electrode pastes to the production of graphite joints, and developed a new type of ultra-high-power graphite. Electrode joints have been industrialized. Compared with graphite electrode joints, which are traditionally produced in China, the microstructure is significantly different. The φ331mm high-power joint prepared by using carbon fiber + powder method has a flexural strength of 26MPa, which is better than the previous joint than the product, and has better index stability. Independent innovation ability of key preparation technology for graphite electrode joints.
