Electric arc furnace

Electric arc furnace is used for high-melting-point alloys such as iron and steel. This method is mainly used in mini mill where scrap steel obtained from used automobiles and other products is recycled. History: The first electric arc furnace was made in by a Frenchmen Paul Heroult, and the first commercial use of electric arc furnace was started in USA. These furnaces were widely used in WorldWar II to alloy steel and later electric steel making began to expand. Since the cost of establishing an electirc arc furnace was less, so they started flourishing throughout Europe. Types of Electric Arc Furnace: There are various type of electric furnaces that are available which can carry from 1 ton to tons of melting works. The carbon rods that penetrated in the furnace can be two or three in numbers.

The electric arc furnace is mostly accepted by steel making companies, thus a large quantity of graphite electrode are consumed. Why is that? This greatly reduces the energy required to make steel when compared with primary steelmaking from ores. Another benefit is flexibility: while blast furnaces cannot vary their production by much and can remain in operation for years at a time, EAFs can be rapidly started and stopped, allowing the steel mill to vary production according to demand. During the peak of global financial meltdown in , an estimated quantity of only 1 million tonne was produced in USA employing EAF technique. Although steelmaking arc furnaces generally use scrap steel as their primary feedstock, if hot metal from a blast furnace or direct-reduced iron is available economically, these can also be used as furnace feed.

The first, and perhaps the most important decision you will need to make when purchasing a new furnace is deciding what type of fuel source your new furnace will use. For most people, this will mean choosing between gas furnaces and electric furnaces. Today, I would like to help you determine which of these fuel sources is right for you by sharing a bit more information with you concerning electric furnaces.

Today in this article we will be going to see the overview of Electric Arc Furnace, which includes it's definition, types, construction details, working principle, applications, advantages, and disadvantages. So let's dive into the paper right now. It is an extremely hot enclosed region, where heat is produced using electrodes for melting certain materials such as steel scrap without changing the electrochemical properties of the material metal.

The Advantages And Disadvantages of Electric Furnaces

An electric arc furnace EAF is a furnace that heats charged material by means of an electric arc. Industrial arc furnaces range in size from small units of approximately one ton capacity used in foundries for producing cast iron products up to about ton units used for secondary steelmaking.

Не обращая внимания на устремленные на него любопытные взгляды десятков пар глаз, Беккер шагнул в толпу. Он ослабил узел галстука и рухнул на стул у ближайшего свободного столика. Казалось, что с той минуты, когда рано утром ему позвонил Стратмор, прошла целая вечность. Сдвинув в сторону пустые пивные бутылки, Беккер устало опустил голову на руки. Мне нужно передохнуть хотя бы несколько минут, - подумал. В нескольких милях от этого места человек в очках в железной оправе сидел на заднем сиденье фиата, мчавшегося по проселочной дороге. - Клуб Колдун, - повторил он, напомнив таксисту место назначения.

Со своего места Сьюзан могла видеть всю комнату, а также сквозь стекло одностороннего обзора ТРАНСТЕКСТ, возвышавшийся в самом центре шифровалки. Сьюзан посмотрела на часы. Она ждет уже целый час. Очевидно, Анонимная рассылка Америки не слишком торопится пересылать почту Северной Дакоты. Сьюзан тяжело вздохнула.
