Many of us must know steel. We employ it in your everyday routine. But have you noticed how you can~the way to~tips on how to~the best way to~ways to produce it? And what will it decide to try produce it? This is the steel is made in a big factory and it’s also cooked inside a giant stove called furnace. And also the cooking itself takes numerous ingredients inside.
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 has become increasingly intense, elevating the requirement for a much more efficient melting process. Capacities with the transformers increasingly becoming larger and electric furnaces are growing larger worldwide. Within this manufacturing environment, graphite materials which have durability for larger-power operation are essential much more for that use as Graphite Electrode (GE).
GE are produced from carbon. Carbon is a nonmetal element by having an atomic number 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 that are strictly selected.
Graphite features a higher heat transfer rating, effectiveness against higher temperatures, and possesses more strength against thermal shock than many other materials. Moreover, it excels in machinability in order to meet the requirements for the broader variety of dimensions. Thus, graphite may be the optimum material for scrap-melting electrodes.
GE are typically consumed at high temperatures because of the reaction with oxygen for being CO, CO2. The oxidation of electrodes starts at 500oC and accelerates its speed at 800oC (inside the furnace). Usage of graphite electrodes by sublimation occurs at 3400o. The velocity of sublimation is proportional towards the increase of current density.
Meanwhile, utilization of quality GE leads to contributions to saving energy and environmental conservation. Electric arc furnaces, together with the main objective 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 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 including 123 Kgs (10″ x 60″) to 2060 Kgs (30″ x 110″).
