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.
The technology and equipment has stride into the advanced level worldwide: By importing core equipment of key processes from the United States, Germany and Japan, the technology and equipment of Shida Carbon has stood on the same line along with the most advanced carbon companies, more importantly our product quality has reached the advanced level as well.
- The shortest construction time: 10 months to complete the LWG furnace；
- The highest level of energy saving and environmental protection: By our independent integration and innovation, the car-bottom baking furnace was creatively designed and built with a tail gas incineration and waste-heat power generation system, which effectively solved the pollution problems.
- The technology and equipment has stride into the advanced level worldwide: By importing core equipment of key processes from the United States, Germany and Japan, the technology and equipment of Shida Carbon has stood on the same line along with the most advanced carbon companies, more importantly our product quality has reached the advanced level as well.
- The debugging time of isotropic graphite production line has made a shortest record among carbon industry.
