spare parts for electric arc furnaces

electric arc furnaces introduction

An Electric Arc Furnace (EAF) is a furnace that heats charged material by implies of an electric arc. Arc furnaces range in size from tiny units of around one particular ton capacity (used in foundries for creating cast iron goods) up to about 400 ton units used for secondary steelmaking. Arc furnaces used in study laboratories and by dentists may possibly possess a capacity of only a couple of dozen grams. Arc furnaces differ from induction furnaces in that the charge material is straight exposed to an electric arc, and the current inside the furnace terminals passes through the charged material.

Advantages of electric arc furnace for steelmaking

The use of EAFs permits steel to become made from a 100% scrap metal feedstock. This significantly reduces the energy expected to make steel when compared with main steelmaking from ores. An additional advantage is flexibility: while blast furnaces can't vary their production by substantially and are never ever stopped for many years at a time, EAFs can be rapidly began and stopped, allowing the steel mill to vary production in accordance with demand. During the peak of global economic meltdown in 2009, an estimated quantity of only 1 million tonne was made in USA employing EAF technique. Although steelmaking arc furnaces commonly use scrap steel as their key feedstock, if hot metal from a blast furnace or direct-reduced iron is offered economically, these may also be used as furnace feed.

A typical steelmaking arc furnace would be the supply of steel to get a mini-mill, which may possibly make bars or strip product. Mini-mills may be sited somewhat near for the markets for steel products, plus the transport needs are much less than for an integrated mill, which would normally be sited near a harbour for access to shipping. our company can supply spare parts for electric arc furnaces in India.
