- Electric arc furnace's development historyFrench Heroult (P.L.T.Héroult) used the high temperature of the electric arc of the electrode to develop an alternative energy source for coal and invented the electric arc furnace for industrial direct smelting from 1888 to 1892. At first, the electric arc furnace was only used for the production of calcium carbide and ferroalloys. It was not until 1906 that it was developed for steelmaking, which enabled the economical and large-scale recycling of steel scrap.ZBTECH News October 21, 2020
- How an electric arc furnace work?Electric Arc Furnace Arc furnace provides a simple and effective way of melting various grades of scrap and then going ahead to refine the metal to desired specification. It is also useful in making all kinds of steels including tool steels and alloy steels. This provides a method of utilising lZBTECH News October 06, 2020
- Electric arc furnace's 4 classification methodsThere are many ways to classify electric arc furnaces.According to the melting form of the electrode, it is divided into(1) Non-consumable electrode type electric arc furnace, which uses tungsten or graphite as the electrode, and the electrode itself is not consumed or consumed very little during thZBTECH News October 23, 2020

- 7 advantages of electric arc furnaceElectric arc furnaces use electric energy as their main energy source. Electric energy is arc drawn through the discharge of graphite electrodes and the charge to produce high temperatures above 2000 ~ 6000 ℃, and the scrap steel raw materials are melted by means of arc radiation, temperature convecZBTECH News October 26, 2020
- Main features of electric arc furnaceAlthough EAF steelmaking has many advantages, however, due to the problems of scrap and electricity cost in China, EAF steelmaking can not compete with converter steelmaking in ordinary steel and long-term products. EAF steelmaking only occupies a leading position in the production of special steelZBTECH News October 28, 2020
- Optimization of EAF technologyWe have optimized the EAF technology to achieve the best balance among raw materials, scrap preheating, energy saving and environmental protection, process control, automation control, smelting cycle and production capacity.Electric energy is input into EAF through graphite electrode, and the arc beZBTECH News October 30, 2020
- Main functions of ladle refining furnace1. The function of increasing the temperature of molten steel and heat preservation. The molten steel obtains new heat energy through arc heating, which not only enables the addition of alloy and composition adjustment during ladle refining, but also the addition of slag material, which is convenienZBTECH News November 02, 2020
- Features of electric arc furnaceElectric arc furnaces use electric energy as their main energy source. Electric energy draws arcs through the discharge of graphite electrodes and the charge to generate a high temperature of 2000 ~ 6000 ℃ or more.
