The principle of electric arc melting of metals and alloys

A method of electric arc melting usually produces various grades of stainless steels. Scrap and various alloying elements (for example, ferrochrome, ferronickel) are loaded into the capacity of the electric arc furnace. As in the case of the basic oxygen process, oxygen is blown into the steel cleaning furnace, and lime and fluorspar are added to mix with impurities and form a slag.

The loaded material is heated by an electric arc (passing current through the carbon electrodes) until the metal melts. After samples were taken to check the chemical composition of the steel, the furnace is tilted so that it is possible to pour out the slag that is on the surface of the molten steel. The furnace is then tilted in the opposite direction, and the molten steel is poured into the ladle.

Using the technology of electric arc melting, it is possible to load even 100% of scrap into the furnace, but in this case it is difficult to accurately determine the chemical composition. Depending on the capacity of the transformer and the size of the tank, the typical time of a single cycle of the duration of electric arc melting is 50… 90 minutes.

Urgency of application

Electric arc melting is used to produce special quality steels and alloys. The most famous of them are stainless corrosion-resistant steels, in which chrome and nickel are added. Similar technology is also melted tool steel, and other alloys of special purpose.

Electric arc furnaces

The main task of most modern electric arc furnaces is to convert the solid raw material into liquid crude steel as soon as possible and then refine it in subsequent secondary steelmaking processes. This occurs during the residence time of the metal in the melt stage, when oxygen and carbon powder are added to the liquid bath. The total theoretical energy required to melt the scrap and to overheat to typical temperatures requires about 350 to 370 kWh / t of steel. In practice, the use of energy depends heavily on the range of products, local costs for materials and energy. The resulting figures are usually specified for a certain type of furnace. Factors such as the composition of raw materials, the rate of input of power and the phase of operation of the furnace (afterburning, preheating scrap, etc.) can significantly affect the balance.

Supplier — AvekGlob Company — offers to purchase various metals and alloys in any quantity and range of sizes obtained by electric arc melting technology.
