【正文】 converter was selected. Based on the converter material balance and heat balance calculation， we pleted the main equipment for steelmaking plant selection and design parameters， and the pletion of the main equipment selection， the design of steelmaking process. Furthermore， the technical economy parameters was calculated， the main process plant layout and equipment layout were designed. Prepared a manual， drawing a converter furnace map， areal workshop and section plane blueprint .Translated a English paper into Chinese.Key words: BOF steelmaking workshop；processing designing；converter material balance and heat balance calculation；Secondary refining；casting目錄1 煉鋼車間設(shè) 計(jì)方案
