According to the development trend of electric furnace steelmaking and the trend of general contracting of refractory materials, we should pay attention to refractories for electric furnaces as general contracting of refractory materials.The life of electric smelting furnace is not only closely rela
READ MOREAlthough 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 steel
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.
READ MOREElectric arc furnace uses the high temperature generated by the electrode arc to smelt ores and metals. When the gas discharge forms an arc, the energy is very concentrated, and the arc zone temperature is above 3000 ℃. For smelting metals, electric arc furnaces are more flexible than other steelmak
