The Manufacturing Process of Graphite Electrodes. The manufacturing process of graphite electrodes is from the preparation of the raw materials (a series of crushing, calcining, milling, sieving, and finally mixed together) to the kneading and pressing, and then baking, Impregnation, graphitizing, machining, and finally the graphite electrode products.
Graphite electrodes are divided into 4 Types: UHP Graphite electrodes, SHP Graphite electrodes, HP Graphite electrodes, RP Graphite electrodes. UHP Graphite Electrode The production process for UHP grade: Needle coke and pitch are mixed and then molded.
According to the USGS, U.S. (synthetic) graphite production in 2006 was 132,000 tonnes valued at $495 million and in 2005 was 146,000 tonnes valued at $391 million, and high-modulus graphite (carbon) fiber production in 2006 was 8,160 tonnes valued at $172 million and in 2005 was 7,020 tonnes valued at $134 million. 2.

Graphite features a polycrystalline structure and is based on the production technology related to ceramic materials. Due to its physical and chemical properties graphite is an excellent electrode material for use in electric arc furnaces.
Production. the Hall-Héroult. The raw material for the extraction of aluminium is aluminium oxide, also called alumina, produced from bauxite. Direct current of a very high intensity is passed through the anodes in the process.
Graphite electrode manufacturing process Home / graphite electrodes news, Technology News / Graphite electrode manufacturing process Graphite electrode is made of petroleum coke, needle coke and coal pitch, through calcining 、 batching 、 kneading 、 forming 、 baking 、 Impregnation, graphitizing and machining.
It was established in 1998, has an annual output of 30,000 tons of φ300-φ700mm graphite electrode and 10,000 tons of special carbon shaped graphite products. Ordinary power, high power, ultra high power graphite electrodes are widely used in electric arc steelmaking furnaces, ladle furnaces, ore electric furnace smelting and electric ...
Graphite (/ ˈ ɡ r æ f aɪ t /), archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure.It occurs naturally in this form and is the most stable form of carbon under standard conditions.Under high pressures and temperatures it converts to diamond.Graphite is used in pencils and lubricants.
Graphite electrodes serve to transfer the electrical energy from the power supply to the steel melt in the EAF bath. They are typically made using premium petroleum needle coke, coal tar pitch, and some additives (Fruehan, 1998).Specification of needle coke for the manufacture of large diameter graphite electrodes is shown in Table 12.12.
The Production Process. The production process for the manufacture of graphite electrodes consists of the following production steps: Mixing, Forming, Baking, Impregnating, Rebaking, Graphitizing, Machining.
Graphite India Limited. Graphite India Limited (GIL) is the pioneer in India for manufacture of Graphite Electrodes as well as Carbon and Graphite Speciality products. GIL's manufacturing facilities are spread across 6 plants in India and it has also got a owned subsidiary at Nuremberg, Germany, by name Graphite COVA .
