| | RP Graphite Electrode (5th May 23 at 7:51am UTC) | | RP Graphite Electrode DESCRIPTION:
RP Graphite Electrode
Raw Material:petroleum coke and coal pitch (as binder)
Grade: UHP, HP, RP
Diameter: 75mm-700mm
Length: 1300-2700mm
FEATURE:
Good Electric
Thermal Conductivity
High Density
APPLICATION:
Graphite electrodes are used mainly in ladle furnaces, electric-arc furnace steelmaking, Yellow phosphorus furnace, Industrial silicon furnace or melting copper.
Graphite electrode production characteristics锛?/strong>
The main raw material for the production of graphite electrode is petroleum coke (including needle coke). Asmall amount of asphalt coke can be added to the production of ordinary power graphite electrode. The bonding agent is coal asphalt.
(1) The production process is multiple and the production cycle is long. The production cycle of ordinary power graphite electrode is about 45 days, and the production cycle of ultra-high power graphite electrode is more than 70 days. Joints that require multiple impregnations have longer production cycles.
(2) high energy consumption, 1t ordinary power graphite electrode needs to consume about 6000kW鈥 power, gas or natural gas thousands of cubic meters, metallurgical coke particles and metallurgical coke powder (secondary energy) about 1t.
(3) The production of graphite electrode process, need a lot of special machinery and equipment and special structure of the kiln, construction investment is large, investment payback period is long.
(4) Graphite electrode production process produces a certain amount of dust and harmful gases, so it is necessary to take sound ventilation dust removal and elimination of harmful gas environmental protection measures.
