Electric Arc Furnace Cooling System The history of electric arc furnace (EAF) steelmaking is not very old. It is only slightly more than a century when the first furnace was commissioned to melt steel by utilizing electric power. The initial development of the technology took place, since these furnaces made it possible to easily achieve …
Read MoreMagnesia-Carbon Refractories There is some confusion which can arise from the term magnesia (MgO) refractory. The American Society for Testing and Materials (ASTM) defines magnesia as ‘a dead-burned refractory material consisting predominantly of crystalline magnesium oxide’, but that is not the terminology used at every place. The terms magnesite, magnesia and MgO are sometimes used inter-changeably …
Read MoreAutomation Control and Modelling of Electric Arc Furnace The electric arc furnace (EAF) constitutes the main process in scrap / DRI (direct reduced iron) based steelmaking and the second most important steelmaking process route in terms of global steel production. It is the main process for recycling of ferrous scrap. It was invented in 1889 …
Read MoreCarbon Neutral Steelmaking Iron and steel production industry is the single largest sector in terms of total global fossil and industrial emissions, making up around 7 % to 9 % of greenhouse gas (GHG) emissions. At the same time, steel is the primary material component for modern industrial societies. Further consumption of steel is going …
Read MoreConsteel Electric Arc Furnace Process Consteel process is a patented process. It is an innovative energy conservation technology for scrap pre-heating in an electric arc furnace (EAF) developed by ‘Intersteel Technology Inc., Charlotte, North Carolina (since 1994 a part of Techint, Tenova S.p.A.). The first industrial application of the Consteel technology took place in 1989, …
Read MoreFoaming of Slag in Electric Arc Furnace Slag foaming has become an important and critical practice for the modern electric arc furnace (EAF) since a good foaming slag contributes considerable efficiency and other benefits to the process. The quality of the slag foaming is an important factor in the EAF steelmaking process since it ensures …
Read MoreRefractory Lining of the Electric Arc Furnace Refractories are those materials which withstand high temperature without a significant change in chemical or physical properties. Refractory materials are very important to the electric arc furnace (EAF) operation as they allow the containment of the liquid steel in the furnace hearth without damaging the furnace structure. The …
Read MoreMetallurgical Industrial Furnaces An industrial furnace is essentially a thermal enclosure and is employed to process raw materials at high temperatures both in solid state and liquid state. The principle objectives of an industrial furnace are (i) to utilize heat efficiently so that losses are minimum, and (ii) to handle the different phases (solid, liquid …
