Specifics You Have To Be Informed On Graphite Electrode And How Is It Involved In The Steel Making Solution?

Many of us got to know steel. We employ it inside your everyday activity. But have you noticed how you can produce it? As well as what should it take to produce it? Fundamentally the steel is made in the big factory and it is cooked in the giant stove called furnace. As well as the cooking itself takes so many ingredients inside it.

The Blast Furnace and Electric Arc Furnace methods are the two major approaches for producing iron and steel products. Scrap melting is the major process utilizing Electric Arc Furnaces. Recently, industry competition is now increasingly intense, elevating the requirement for an infinitely more efficient melting process. Capacities in the transformers are receiving larger and electric furnaces are increasing larger worldwide. In this manufacturing environment, graphite materials which may have durability for larger-power operation are needed much more for that use as Graphite Electrode (GE).

GE are made from carbon. Carbon is a nonmetal element by having an atomic quantity of 6 and the atomic symbol “C”. Carbon may be the base of organic chemistry, closely in connection with organic matter and life activity. Manufacturing excellent graphite electrodes requires quality materials which are strictly selected.

Graphite features a higher heat transfer rating, potential to deal with higher temperatures, and has more strength against thermal shock than many other materials. Moreover, it excels in machinability in order to meet certain requirements to get a broader array of dimensions. Thus, graphite is the optimum material for scrap-melting electrodes.

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

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

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

Raw material transporting
Kneading
Extruding
Baking
Pitch Impregnation
Re-Baking
Graphitization
Machining
Inspection
Shipment
The typical sizes for graphite electrodes are 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″).
