يتكون فرن القوس الكهربي الذي يعمل ب

يتكون فرن القوس الكهربي الذي يعمل بالتيار المستمر من فطب كهربائي يكون فوق سطح المصهور و قطب في القاع، أما الفرن الذي يعمل بتيار متردد فيعمل بثلاثة أقطاب على السطح. وينظم طول القوس الكهربي بواسطة منظم للأقطاب . ويتطلب فرن القوس الكهربي قدرة وكفاءة عالية من الشبكة الكهربائية المغذية له حيث يتغير مرور التيار بشدة أثناء عملية الصهر، ومن الممكن أن تؤثر الأقواس الكهربائية على الشبكة بطريقة عكسية . ويتكون وعاء الفرن من ثلاثة أجزاء ( وعاء القاع ووعاء علوي وغطاء ) ، ويمكن تمييله هيدروليكيا لتفريغ ما فيه من مصهور. يتكون الجزء الخارجي منه من الحديد الصلب وهيكون في العادة مبردا بالماء ومن الداخل مبطنا بمواد تتحمل الحرارة العالية . تقدر أحجام الأفران بما تحويه من المصهور ، فمنها ما تصل سعته إلى 1 طن في المعامل الصغيرة أو قد تصل إلى 300 طن من المصهور للمصانع الحديد والصلب الكبيرة.

Electric arc furnace consists which operates from DC electric Aftb be above the surface of the molten and the pole at the bottom, the oven works stream AC thereby acting three poles on the surface. It regulates the length of the electric arc by regulator of the poles. The electric arc furnace requires the capacity and high efficiency of the feeder him where the passage of the current changes strongly during the melting process of the electric grid, it is possible to affect electric arcs on the grid in reverse.
The pot furnace consists of three parts (pot bottom and upper bowl and lid), can Tmialh hydraulically to unload it from the molten. The outer part of it consists of iron and steel Hikon usually cooled with water and the inside lined with materials bear high heat.
Estimated sizes of furnaces and containing molten, some of which capacity of up to 1 ton in small laboratories or up to 300 tons of molten iron large factories and steel.

The continuous-current electric arc furnace consists of an electrical deptomy that is above the surface of the molten and a pole at the bottom, while the AC-operated furnace is operated by three electrodes on the surface. The length of the arc is regulated by a electrode regulator. The electric arc furnace requires the high capacity and efficiency of its nourishing electrical grid as the current passes change dramatically during the smelting process, and electrical arcs can adversely affect the grid.
The oven bowl consists of three parts (bottom bowl, top bowl and lid), and can be hydraulically tilted to empty its molten. The exterior of it is made of steel and will usually be chilled with water and from the inside lined with materials that withstand high heat.
The sizes of the furnaces are estimated to contain molten, including up to 1 ton capacity in small factories or up to 300 tons of molten for large iron and steel factories.

The electric arc furnace is a continuous current working electrode on the melting surface and the bottom of the electrode, while an alternating current arc furnace working on the surface of the three electrodes. The arc length is regulated by the electrode regulator. The arc furnace needs a high capacity and high efficiency grid feeder. The strong change of current channel in the smelting process may affect the arc in a reversible way network.
The furnace is composed of three parts, more than one container and cover, which can be unloaded and melted hydraulically. Its external part is made of iron and steel structure, which is usually water-cooled and lined with high temperature resistant materials.
The estimated size of the furnace, including its capacity, does not match that of a small module of one ton or a melting furnace of up to 300 tons in a large steel plant.
