We all got to know steel. We use it with your everyday activity. But ever thought about how to produce it? And what will it decide to try produce it? Basically the steel is produced inside a big factory which is cooked inside a giant stove called furnace. Along with the cooking itself takes countless ingredients in it.

The Blast Furnace and Electric Arc Furnace methods will be the two major methods for producing iron and steel products. Scrap melting is the major process utilizing Electric Arc Furnaces. Recently, industry competition is becoming increasingly intense, elevating the requirement of a much more efficient melting process. Capacities with the transformers increasingly becoming larger and electric furnaces are increasing larger worldwide. With this manufacturing environment, graphite materials which may have durability for larger-power operation are required a lot more for the use as Graphite Electrode (GE).

GE are produced from carbon. Carbon is often a nonmetal element by having an atomic number of 6 as well as the atomic symbol “C”. Carbon will 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 includes a higher heat transfer rating, effectiveness against higher temperatures, and possesses more strength against thermal shock than other materials. Moreover, it excels in machinability to satisfy the needs for the broader variety of dimensions. Thus, graphite is the optimum material for scrap-melting electrodes.

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

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

Production organization of graphite electrodes might be divided as 10 stages the subsequent:

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