China graphite electrodes factory:Shijiazhuang huanan carbon factory

Introduction

The graphite electrode is mainly made of petroleum coke and needle coke, and the coal asphalt is used as a binder. It is made by calcination, distributing, kneading, forming, roasting, graphitization and machining. It's a conductor which release electric energy in the form of electric arc in the electric arc furnace heats and melts the material. the charge can be divided into a regular power graphite electrode, a high power graphite electrode and an ultra high power graphite electrode according to its quality index. The main raw material for graphite electrode production is petroleum coke. The regular power graphite electrodes can be added with a small amount of pitch coke. The sulfur content of petroleum coke and pitch coke cannot exceed 0.5%. Needle coke is also required for the production of high power or ultra high power graphite electrodes.

Advantage

The advantage of graphite electrode is that it is easy to process, the electricity discharge processing rate is high, and the graphite loss is small.

Production characteristics

The production period is long. The production period of regular power graphite electrodes is about 45 days, the production period of ultra high power graphite electrodes is more than 70 days, and the production period of graphite electrode joints (nipples) requiring multiple impregnation is more longer.

Application

Mainly used in electric arc steelmaking furnaces, refining furnaces, industrial silicon furnaces, yellow phosphorus furnaces, electric resistance furnaces, etc., as conductive usage. The graphite electrode blank is also used to process a variety of shaped graphite products such as enamel, mold, boat and heating element.
