Diameter 550mm UHP Graphite Electrode,Graphite Electrode for EAF,GE
Sichuan Guanghan Shida Carbon Co., Lts was established in 2001, formerly the Shanxi Jiexiu Shida Carbon which was founded by Mr Zhang Shigong in 1990.
Shida Carbon’s main products are: Graphite Electrode with Diameter 400-700mm,grade RP,HP,UHP, Isotropic Graphite, 600X800X4400mm Graphite Cathode, high quality Graphite Anode, and Small Medium Grain Size Graphite. Shida is the leading manufacturer of graphite electrode in China and we have full production equipment from raw material to graphitization and maching which graruantee our quality stable. Almost all our production equipment are imported from overseas, such Japan milling system, Japan kneading system, Germany technology car-bottom baking furnace.By adoping environment protection measures and innocations, Shida has waste-heat power generation system, the polution problem of Benzo from baking gas which has puzzled the carbon industry for a long time, has been thoroughly solved by us. Shida carbon has been become a benchmark in energy saving and environmental protection of the whole carbon industry.
Shida Carbon is a Hi-Tech enterprise specialized on research and production of new carbon materials, also act as the vice chairman of China Association of Small and Medium Enterprises, director of China Carbon Industry Association, member of Carbon Material Council of Chinese Society for Metals and member of China Special Steel Enterprises Association.
