ABSTRACT:The design of the main task is to design a batch of 85 million tons of electric furnace steelmaking workshop. Using high power electric arc furnace50t, in turn use after LF smelting furnace and the VD furnace refining, finally get billet caster in use. The main production of Q235 alloy steel tube, and in the design process into scrap steel preheating, eccentric furnace bottom, water-cooled hang the steel slag furnace wall, are relatively popular production technology. This design from basic material balance and thermal equilibrium calculation begin. Mainly includes the following several parts: Steel-making Plant Design，casting equipment selection and calculation, refining outside the furnace equipment selection and process arrangement and steelmaking workshop flue gas purification system, etc. Among them is the design of electric furnace steelmaking workshop with the design emphasis of core.
Keywords: Electric Furnace；steelmaking；design；Continuous casting
