摘要 根據設計任務書的要求,完成年產300萬噸合格鑄坯的轉爐車間設計。在設計中,首先對轉爐煉鋼發展現狀和趨勢進行了全面綜述,并系統闡述了目前轉爐煉鋼所采用的新技術、新工藝和新設備。主要對轉爐煉鋼生產的生產規模、產品方案、工藝流程、車間組成和工藝布置進行設計,并對150噸頂底復吹轉爐爐型、原材料的供應系統、供氧系統、轉爐車間煙氣凈化系統、爐外精煉設備以及車間主廠房工藝布置進行了設計計算。此外對轉爐車間的一些主要附屬設施進行了選擇并給出了其技術性能參數。并進行了技術經濟分析。
關鍵詞 產品大綱;頂底復吹轉爐;氧槍;轉爐車間
Abstract This paper is about the process which designed for the steel-making plant with a 3 million tons production per-year.Firstly,we have a overview of the current situation and trends of the converter steel-making,then we systematically expound the new technology,new technics and new equipment which we use.We mainly consider about the range of the production ,the blueprint,the procession and the composition and arrange for the workshop.Also the paper made the calculation about the plant which includes the material and heat balance calculation of the converter, design of the oxygen lance, the height and length of the converter stride and the feed stride, and the furnace type of top bottom combined blowing convert...
