500mm Hp Carbon Graphite Electrodes 20 Inch For Electric Arc Furnace Ladle Furnace
500mm HP Carbon GE , 20 Inch HP Graphite Electrode for Electric Arc Furnace/Ladle Furnace
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 and so on. Shida Carbon 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.
