Design Description
In 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, ultra-high 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 ultra-high 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 →ultra-high 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, multi-function characteristic and has the characteristics of sustainable development.
Key Words:ultra-high power electric arc furnace,AOD refineing furnace, Steelmaking
