Company Profile

Sichuan Guanghan Shida Carbon Co.,Ltd. was established in 2001, formerly the Shanxi With years of tireless research and practice, Shida Carbon has gained five invention patents and more than Jiexiu Shida Carbon which was founded by Mr. Zhang Sigong in 1990. ten utility model patents of graphite electrodes and isostatic graphite production, the technology, equip- ment has reached the highest level internationally. Shida Carbon now is a Hi-Tech enterprise specialized on research and production of new carbon materials, also act as the vice chairman of Association of Small and By adopting environmental protection measures and innovations, such as waste-heat power generation Medium Enterprises, director of China Carbon Industry Association, member of Carbon system, the pollution problem of benzo from baking gas which has puzzled the carbon industry for a long Material Council of Chinese Society for Metals and member of China Special Steel Enter- time, has been thoroughly solved by us. Shida Carbon has become a benchmark in energy saving and prises Association. environmental protection of the whole carbon industry.

Shida Carbon’s main products are: Dia.400-700mm UHP Graphite Electrode, Isotropic Shida Carbon has been standing nearly thirty years, after the global financial crisis, we have made bold Graphite, 600X800X4400mm Graphite Cathode, high quality Graphite Anode, and Small progress against the flow, took the lead in reform and transformation, with the full operation of new Medium Grain Size Graphite. Our products are widely used in the industries of electric production lines and the overall management improving, today Shida has become an international leading arc furnace steel making, submerged arc furnace smelting, solar photovoltaics , EDM, high-tech, environment friendly carbon enterprise. All of these progresses are inseparable from our devel- fine chemicals, high temperature treatment, precision casting，nuclear power, electro- oping concept which Shida always hold. Shida will continue to innovate and exploring forward in the lytic aluminum and etc. furture.

After the global financial crisis in 2009, Shida Carbon started constructing production lines of the three upgrading and transferring products. With the great efforts of Shida people, we have successfully completed the project in only 3 years. In August 2013, both the Dia.600mm UHP graphite electrode and Dia.620X600MM Isotropic graphite has gained the appraisement of sci-tech achievements by Sichuan Science and Technology Department. Our new project has created many new records among carbon industry at China and aboard.

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 effec- tively 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 quali- ty has reached the advanced level as well.

The debugging time of isotropic graphite production line has made a shortest record among carbon industry. 03 /04 SHIDA CARBON SHIDA CARBON SHIDA CARBON

1 2 3 4 Screw lifting plug into socket of one end and place soft protection material under the other end（see pic.1） to avoid damaging nipple;

Blow dust and dirt on the surface and socket of electrode and nipple with compressed air; use brush to clean if compressed air cannot do it well (see pic.2);

Use a proper torque value (see recommended torque value table) to properly lock elec- trode (see pic.3);

In order to avoid crushes during furnace charging, please place bulk materials at the furnace bottom; meanwhile please do not place lime or any other non-conductive materials right under the electrodes, otherwise it will decrease electric conduciveness and cause breakage; Recommended Torque Meter Attention furnace cover’s position in order to avoid scratching or damaging when rising and lowering electrodes; Diameter（mm） Torque Value（N.m）

400 1075 If any connection gap observed after jointing, the causes must be identified and elimi- 450 1375 nated before use; 500 1770 Electrode clamper must be hold at the proper position: outside the safety lines of the 550 2460 higher end; 600 3440 4520 650 Attention impact from collapsing materials during melting, operations of rising and 700 6000 lowering must be taken on time;

Electrode breakage happens during refining period due to thinner electrodes cause nipple dropping and consumption increase, please don’t use electrodes to raise carbon content.

Please don’t mixed use electrodes from different manufacturers due to raw material and technologies are different from each manufacturer, chemical and physical proper- ties are various as well.
