Characteristics of the experimental electric furnace steel-making aspects of analysis, the experimental electric furnace steel making is the main advantage of the arc heat, temperatures up to 4000 ° C in the arc active region. The smelting process is generally divided into the melting of the oxide phase and restore of not only cause oxidative atmosphere at high temperature furnace, but also result in a reduction atmosphere, so dephosphorization high desulfurization efficiency. Can be added to the molten iron, pig iron, direct reduced iron, hot briquetted. Longer duration of heat, generally at least twice the time of smelting. 
 Experimental smelting temperature and easy control adjustment, electric arc furnace arc zone temperature up to 3000-6000 ° C, the furnace temperature up to above 2000 ℃, much higher than the general smelting steel temperature, can be used for the smelting of alloy steel of smelting converter can not and stainless steel due to heat generated by the energy needed by the electrodes in short circuit power consumption, the electrical energy consumed by smelting a ton of steel is about 350-600kWh; finished steel in hydrogen, nitrogen content is high. Because in the arc under the action of the furnace air water vapor a large number of dissociation, the generated hydrogen and nitrogen into the molten steel will affect the quality of steel. The arc is a "point" sources of heat, the furnace temperature distribution is uneven, the molten pool is calm, all parts of the molten steel temperature is quite different. The presence of carbonaceous electrodes make liquid steel by carbon difficult to smelting low-carbon steel. 
 Different stages of the experimental electric furnace in the smelting furnace is not only caused by the oxidizing atmosphere, but also result in a reducing atmosphere, the former in favor decarburization and phosphorus removal, the latter has deoxidation, desulphurization, easily oxidized alloy, metal recovery elements and control the composition of the liquid steel. The electric equipment is relatively simple, less investment and set up factories fast, small footprint, and easy to control pollution of scrap iron and steel is one kind of load can save a lot of energy resources, iron and steel scrap steelmaking. In a large steel company in the mining, beneficiation, sintering, coking, iron to steel-making, steel rolling, energy consumption and pollution emissions is mainly concentrated in the steel-making process before. Studies have shown that, compared to the direct steelmaking using scrap and the use of ore iron-smelting and then steelmaking, energy saving 60%, water-saving 40%. 
 Steel is an environmentally friendly resources, direct steelmaking using scrap and the use of ore iron-smelting and then steelmaking compared with emission reduction 86%, 76% of wastewater and waste 97%, cleaner production and waste minimization.
