Facts It Is Advisable To Be Familiar With Graphite Electrode And The Way Is It Linked To The Steel Making Technique?

Many of us have to know steel. It’s used by us inside your everyday life. But have you ever wondered how you can~the way to~tips on how to~the best way to~ways to produce it? Along with what will it decide to try produce it? Simply the steel is produced inside a big factory in fact it is cooked inside a giant stove called furnace. And also the cooking itself takes numerous ingredients in it.

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

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

Graphite includes a higher heat transfer rating, capacity higher temperatures, and it has more strength against thermal shock than many other materials. Moreover, it excels in machinability to meet what’s needed for a broader variety of dimensions. Thus, graphite may be the optimum material for scrap-melting electrodes.

GE are often consumed at high temperatures due to the reaction with oxygen for 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 towards the increase of current density.

Meanwhile, usage of quality GE results in contributions to saving energy and environmental conservation. Electric arc furnaces, with all the main purpose of recycling steel scraps, market reuse of steel products.

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

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 amount of 60″(inch) to 110″(inch). The weights are ranging from 123 Kgs (10″ x 60″) to 2060 Kgs (30″ x 110″).
