Steel Smelting Ladle Furnace Use HP 300 Graphite Electrodes
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.
Graphite electrode series products are made of high quality carbon materials.The main products are: RP graphite electrode, smelting furnace shaped carbon block, impregnated graphite electrode, high power graphite electrode, graphite crucible, electrode paste, recarburizer, and non-standard specifications of shaped carbon products.
PRODUCT DESCRIPTION
Name: HP Graphite Electrode
Model: HP 150mm
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 electrode 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.
graphite electrodes Manufacturer:Shijiazhuang huanan carbon factory
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.
graphite electrodes 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.
