Electric Arc Furnace Melting Procedure

electric arc furnace production process


Electric arc furnaces use electric energy as their main source of energy. The electric energy is drawn through the graphite electrode and the charge of the furnace to generate a high temperature of up to 2000 ~ 6000 ° C, and the scrap steel material is melted by arc radiation, temperature convection and heat conduction. During most time of the melting charge, the high temperature heat source is surrounded by the charge, and the heat loss caused by the high temperature exhaust gas is relatively small, so the thermal efficiency is higher than other steelmaking equipment such as converters. In addition, the electric heating can easily and accurately control the furnace temperature, and the heating operation can be performed under any conditions such as oxidizing atmosphere or reducing atmosphere, normal pressure, or vacuum according to the process requirements.

EAF steelmaking has strong adaptability to the charge. It uses scrap steel as the main raw material, but it can also use solid water such as molten iron (blast furnace or iron furnace), sponge iron (DRI) or hot compact (HBI), and pig iron and liquid iron-containing raw materials.

Hx series arc furnace is open cover and filled from top. It is divided into common power, super power, ultra high power according to the adaption. It is divided into left operation and right operation according to the operation mode. The tapping form includes: tapping from spout and tapping from the eccentric bottom.
