Not many people are aware that there are in fact two different methods to create iron. This includes an electric-arc furnace method or a blast-furnace method. The electric-arc furnace technique recycles iron scrap in the way of melting the metal in the electric-arc furnace. The graphite electrodes in the furnace is what helps the furnace to reach high enough temperatures in order to melt iron. Graphite offers a high-thermal conductivity. It is also highly resistant to impact and heat.
Graphite is also known for its low-electrical resistance. This means it is able to conduct larger electrical currents that are required in order to melt the iron. Over the last few years the graphite electrodes are more efficient than ever, meaning they conduct more power and higher currents. The size of these electrodes have also increased immensely compared to previous years.
https://graphiteelectrodesforsale.com/graphite-electrode-sales/ are utilized in EAF (electric is furnace) and LF (ladle furnace) for the production of steel, smelting processes, silicon-metal production and ferroalloy. The tips of these electrodes have the potential to reach temperature of up to 3000oC, which can be compared to about ½ of what the sun produces. Additionally, graphite offers outstanding mechanical strength, machinability, thermal-shock resistance and thermal expansion. It is the extremely high temperatures which assist in reducing the masses of steel.
– EAF (Electric Arc Furnace)
– LF (Ladle Furnace) and others
In the year 2016, the Electric Arc Furnace was the biggest application-segment in association to value along with volume due to the rise in the adoption of the Electric Are Furnace route in regard to steel manufacturing. This particular segment is predicted to grow at CAGR of 5.2% over forecasted periods.
The graphite electrodes are mainly used in the Electric Arc Furnace for the purpose of steel manufacturing, but it is also use for refinement processes. The increased uses of materials in the electric arc furnaces to processes that involve melting steel scrap and metals will start to increase demands for materials over a projected period.
Graphite offer a few useful properties which is what has made is sought after in the form of electrodes in a number of different applications, such as Electric Arc Steel production. This is because graphite in extremely stable, plentiful and cheap for an extensive range of varying operating conditions, hard/durable, scalable and a great heat conductor and electrical conductor. An immense amount of heat will be generated in the EAS production.
Growth within the steel-orientated sectors which include aerospace and defence, infrastructure, automotive and a number of different construction sectors among others has resulted in a rise in production as well as consumption of different steels. Today, most of the manufacturers have chosen EAF (electric arc furnaces) when it comes to manufacturing steel, which necessitates the graphite-electrodes as its primary component. Because it has become one of the prerequisites in the steel manufacturing processes along with different smelting processes through the Electric Arc Furnace route, demands for the graphite electrodes is in fact directly linked to demands for Electric Arc Furnaces.
