For electric arc furnace
Graphite electrode is mainly used in EAF steelmaking. Electric
furnace steelmaking is the use of graphite electrode into the
current furnace, powerful current arc discharge is generated in the
bottom electrode by gas, produced by arc heat to smelting.
According to the electric capacity, equipped with a graphite
electrode with different diameters, in order to make the electrode
in continuous use between electrodes, electrode thread joint.
Steelmaking with graphite electrode for the total amount of
graphite electrode in 70 ~ 80%.
For ore heat furnace
Graphite electrode submerged arc furnace is mainly used in the
production of iron alloy, pure silicon, phosphorus, copper and
calcium carbide, which is characterized by the lower conductive
electrode buried in the burden, so in addition to the arc between
the plate and the burden of generating heat, the current through
the charge by charge resistance can also produce heat. Silicon
consumed per ton of graphite electrode of about 150kg per ton of
yellow phosphorus, consumes about 40kg graphite electrode.
For resistance furnace
Graphitization furnace, melting glass production of graphite
products with the furnace and the production of silicon carbide
electric stove are resistance furnace, the material is loaded in
the furnace heating resistor, it is heated object. Usually, the
graphite electrode conductive insert furnace head wall bed end, so
the conductive electrode is not continuous consumption.
In addition, a graphite electrode blank is also used for processing
various crucible, Shi Mozhou ware, casting and vacuum electric
furnace heating hot body shaped products. As in the quartz glass
industry, the production of LT electric melting pipe with graphite
electrode blank 10t, the production of LT quartz bricks of
consumable electrode blank 100kg.
