Information You Need To Understand About Graphite Electrode And How Is It Part Of The Steel Making Technique?

All of us got to know steel. It’s used by us in your everyday living. But ever wondered the way to produce it? Along with what does it decide to use produce it? Fundamentally the steel is produced within a big factory which is cooked inside a giant stove called furnace. And also the cooking itself takes numerous ingredients within it.

The Blast Furnace and Electric Arc Furnace methods include the two major methods for producing iron and steel products. Scrap melting may be the major process utilizing Electric Arc Furnaces. Recently, industry competition is now increasingly intense, elevating the necessity for an infinitely more efficient melting process. Capacities from the transformers increasingly becoming larger and electric furnaces are increasing larger worldwide. Within this manufacturing environment, graphite materials who have durability for larger-power operation are expected a lot more for your use as Graphite Electrode (GE).

GE are made from carbon. Carbon is really a nonmetal element by having an atomic variety of 6 and the atomic symbol “C”. Carbon could be the base of organic chemistry, closely related to organic matter and life activity. Manufacturing excellent graphite electrodes requires quality materials which might be strictly selected.

Graphite carries a higher heat transfer rating, potential to deal with higher temperatures, and it has more strength against thermal shock than many other materials. Moreover, it excels in machinability to fulfill the requirements for a broader range of dimensions. Thus, graphite could be the optimum material for scrap-melting electrodes.

GE can be consumed at high temperatures because of the reaction with oxygen being CO, CO2. The oxidation of electrodes starts at 500oC and accelerates its speed at 800oC (within the furnace). Utilization of graphite electrodes by sublimation occurs at 3400o. The pace of sublimation is proportional to the increase of current density.

Meanwhile, using quality GE ends in contributions to saving energy and environmental conservation. Electric arc furnaces, using the main purpose of recycling steel scraps, promote reuse of steel products.

Production organization of graphite electrodes can be divided as 10 stages the following:

Raw material transporting
Kneading
Extruding
Baking
Pitch Impregnation
Re-Baking
Graphitization
Machining
Inspection
Shipment
The common sizes for graphite electrodes originate from diameter 10″ (inch) to 30″(inch) and from amount of 60″(inch) to 110″(inch). The weights are which range from 123 Kgs (10″ x 60″) to 2060 Kgs (30″ x 110″).
