【正文】 Design DescriptionIn this paper, we have designed a electric arc furnace workshop which can produce 600,000 tons of qualified stainless steel a the ascertained of the products outline, eaf material balance, thermal equilibrium calculation, ultrahigh power electric arc furnace’s type design ,the workshop process design and workshop layout, we finaly identified a 600,000 tons of qualified stainless steel smelting plant with which a 600,000 tons of ultrahigh power electric arc furnace, a chastening AOD furnace and a caster is as the main production according to the domestic and foreign steelmaking technology trends, the development direction of the steel product,we finally selected the short flow process，scrap steel →ultrahigh power electric arc furnace→AOD furnace refineing→continuous casting, which is advanced and has a bigger development Design scheme based new technology and high efficienc as the principle, fully embodies the advanced, flexible, multifunction characteristic and has the characteristics of sustainable development.Key Words：ultrahigh power electric arc furnace，AOD refineing furnace, Steelmaking目錄設(shè)計(jì)總說明
