It consist of the plant scale choosing and ensuring main system, the calculation and ensuring of the main equipment, and also including some new technology.The importance of the design is conforming the main system of the plant, including the system molten iron provided, the providing system of laxity, the providing system of ferroalloy, pretreatment of molten iron, the cleaning system ,the treatment system of slag and so on.Compared with other schemes, these methods are quite adaptable to this design and they are advanced technologies in the world. The followings are mainly included in the design: the calculation of the converter, the calculation of oxygenlance, the calculation and selection of fluegas cleaning system, the calculation of the workshop equipment and the arrangement of each span. What’s more, the design has adopted a lot of new technologies such as:slagsplash to protect the stove, molten iron predesulphurizing based on magnesium and so on. These technologies are all reached the advanced level in the world.Keywords: BOF of 60 tons, convert, the calculation of the plant design, system目 錄III目 錄摘 要 .............................................................................................................................IABSTRACT.......................................................................................................................II第 1 章 緒論 ..................................................................................................................1 鋼鐵工業(yè)在國民經(jīng)濟中的地位和作用 ................................................................................1 煉鋼工藝的發(fā)展及現(xiàn)狀 ........................................................................................................1 ................................................................................................................................2第 2 章 產(chǎn)品方案及金屬料平衡估算 ..........................................................................3 產(chǎn)品大綱 .................................................................................................................................3 全廠金屬料平衡估算 ............................................................................................................3 技術可行性 ............................................................................................................................4第 3 章 轉爐車間生產(chǎn)工藝流程 ..................................................................................5 設計原始條件 ........................................................................................................................5 生產(chǎn)工藝流程圖 ....................................................................................................................5 本章小結 ................................................................................................................................7第 4 章 轉爐煉鋼的物料平衡和熱平衡計算 ..............................................................8 物料平衡計算 .........................................................................................................................8 熱平衡計算 ...........................................................................................................................15 本章小結 ...............................................................................................................................20第 5 章 原料供應及鐵水預處理方案 ........................................................................21 原料供應 ...............................................................................................................................21 鐵水預處理方案 ...................................................................................................................24 本章小結 ...............................................................................................................................25第 6 章 轉爐座數(shù)及其年產(chǎn)量核算 ............................................................................26 轉爐容量和座數(shù)的確定 .......................................................................................................26 車間生產(chǎn)能力的確定 ...........................................................................................................26 確定轉爐座數(shù)并核算年產(chǎn)量 ...............................................................................................27第 7 章 轉爐爐型選型設計及相關參數(shù)計算 ............................................................................29 轉爐爐型設計 .......................................................................................................................29 轉爐爐襯設計 .......................................................................................................................32 轉爐爐體金屬構件設計 .................................
