Electricity environment and status of electric arc furnaceElectric arc furnaces used for smelting generally have three characteristic working stages:At the beginning of the melting phase, the solid charge is melted, and the energy demand is greatest.Initial refining and heating stageDuring the refin
READ MOREElectric arc furnace steelmaking is the main method for producing medium-high alloy steel and high-quality steel.In energy and resources, more waste and cheap industrialized areas, electric arc furnaces produce ordinary carbon steel, which has accounted for market share growth.With the development
READ MORE1. Refractory materials for electric arc furnace roofThe roof of the electric arc furnace is generally built with high-alumina bricks with an alumina content of 75%-85%. Compared with silica bricks, high-alumina bricks are characterized by high refractoriness, good thermal shock resistance, and high
READ MOREThere 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 th
READ MOREFrench 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.
