The graphite electrode is made of petroleum coke and asphalt coke as aggregate, and coal tar is used as a binder. The production characteristics of graphite electrodes is as follows: It is made of raw materials for calcination, crushing and milling, compounding, kneading, molding, roasting, impregnation, graphitization and mechanical processing. High temperature graphite conductive material. It is called artificial graphite electrode (abbreviated as graphite electrode) to distinguish it from natural graphite electrode prepared by using natural graphite as raw material.

The graphite electrode uses as a conductive electrode material for an electric steelmaking furnace. In 2004, China’s graphite electrode output reached 368,300 tons, and graphite electrode exports exceeded 100,000 tons.
Even though the productivity of graphite electrodes is sometimes high, depending on the feedback from the graphite electrode supplier and the graphite electrode price in a certain period of time, we can see that the graphite electrode will be in short supply in a certain period of time. The main reason is to start from the production characteristics of graphite electrodes.
What are the production characteristics of graphite electrodes?
(1) The production cycle is long. The production cycle of rp graphite electrodes is about 45 days, the production cycle of uhp graphite electrodes is more than 70 days, and the production period of graphite electrode nipples requiring multiple impregnation is longer.
(2) High energy consumption. The production of 1t rp graphite electrode requires about 6000kW·h of electricity, thousands of cubic meters of gas or natural gas, and about 100 g of metallurgical coke and metallurgical coke.
(3) There are many production processes. The production process includes raw material calcination, crushing milling, batching, kneading, forming, roasting, dipping, graphitization and mechanical processing. Its production requires many special mechanical equipment and special structure of the kiln, the construction investment is large, and the investment recovery period is longer.
(4) During the production process, a certain amount of dust and harmful gases are generated, and it is necessary to adopt perfect environmental protection measures for ventilation and dust reduction and elimination of harmful gases.
(5) The carbonaceous raw materials required for production, petroleum coke and coal tar pitch are the production and processing by-products of refining enterprises and coal chemical enterprises, and the quality and stability of raw materials are difficult to be fully guaranteed. In particular, hp/uhp graphite electrode production needle coke, modified electrode asphalt and low quinoline insoluble content special impregnant asphalt, urgently need the attention and active cooperation of China’s petroleum and coal chemical processing enterprises.
