Details It Is Important To Understand About Graphite Electrode And The Best Way Is It Involved In The Steel Making Technique?

We all have to know steel. It’s used by us within your everyday activity. But ever thought about how you can produce it? As well as what can it decide to use produce it? This is the steel is made inside a big factory which is cooked in a giant stove called furnace. And also the cooking itself takes numerous ingredients inside it.

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

GE are produced from carbon. Carbon is a nonmetal element with an atomic quantity of 6 and also the atomic symbol “C”. Carbon is the base of organic chemistry, closely linked to organic matter and life activity. Manufacturing excellent graphite electrodes requires quality materials which might be strictly selected.

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

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

Meanwhile, utilization of quality GE brings about contributions to saving energy and environmental conservation. Electric arc furnaces, with all the main aim of recycling steel scraps, market 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 standard sizes for graphite electrodes are from diameter 10″ (inch) to 30″(inch) and from amount of 60″(inch) to 110″(inch). The weights are starting from 123 Kgs (10″ x 60″) to 2060 Kgs (30″ x 110″).
