摘要

除电弧炉容量外

原料、辅助能源、冶炼品种、冶炼工艺和生产流程等生产状况均影响电弧炉变压器额定容量的确定。经分析得出以废钢为原料的超高功率电弧炉变压器额定容量P

/kVA与吨钢电耗W、变压器功率利用率C

、总通电时间t

、出钢量G之间的关系式为 :P

=(W·G·60 )/(t

同时给出了二次电压的确定方法。结合高阻抗技术

给出超高功率高阻抗电弧炉电抗容量与变压器技术参数的确定方法以及确定石墨电极二次导体截面积的思路

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 P

and parameters- electric power consumption W

transformer power utilization ratio G

total power.on time and steel tapping tonnage W is P

= (W*G

60)/(t

·cosφ·C

)，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.
