Abstract: Besides capacity of electric arc furnace, the production conditions such as chaining, melting steel grade, steelmaking process and production flow sheet influence the determination of rating capacity of transformer for electric arc furnace, It has been obtained by analysis that for ultra-high power (UHP) electric arc furnace using scrap charging the relation fbnnula between rating capacity of transformer Pn and parameters- electric power consumption W, transformer power utilization ratio G , total power.on time and steel tapping tonnage W is Pn = (W*G,60)/(ton·cosφ·C2),and the setting method of transformer's secondary voltage is given. Combined with high-impedance techniques, the methods to determine the reactance capacity and transformer technical parameters of UHP electric arc furnace and the idea to determine the section of graphite electrode are presented in this paper.
