毕业设计(论文) 年产生铁485万吨的高炉炼铁车间设计 摘 要 高炉炼铁是获得生铁的主要手段，是钢铁冶金过程中最重要的环节之一，在国民经济建设中起着举足轻重的作用。高炉是炼铁的主要设备，本着优质、高产、低耗和对环境污染小的方针，设计建造一座年产生铁万吨的高炉炼铁车间，本设计说明书详细的对其进行了高炉设计，其中包括绪论、工艺计算（包括配料计算、物料平衡和热平衡）、高炉炉型设计、高炉各部位炉衬的选择、炉体冷却设备的选择、风口及出铁场的设计、原料系统、送风系统、炉顶设备、煤气处理系统、渣铁处理系统、高炉喷吹系统和炼铁车间的布置等。设计的同时还结合国内外相同炉容高炉的一些先进的生产操作经验和相关的数据，力争使该设计的高炉做到高度机械化、自动化和大型化，以期达到最佳的生产效益。 高炉炼铁设计；喷吹；送风；煤气处理；渣铁处理Blast furnace iron-making is a main means to obtain pig iron, and one of the most important links in the metallurgical course of steel, play a role in holding the balance in national economic construction. The blast furnace is the main equipment of iron-making, in line with the high quality , high yield , low consumption and environmental pollution policy, design and build a blast furnace iron-making workshop producing 4.85million irons every year in advance, this design instruction designs the blast furnace detailedly, including introduction, the craft calculating (Including the batching is calculated, supplies balance and thermal balance), the furnace type of the blast furnace is designed, choice of furnace liner of the blast furnace, the furnace body cools the equipment, the tyueres and design the tap iron field, raw materials system , blow system , furnace roof equipment , coal gas disposal system ,slag iron disposal system ,ejection system, iron-smelting of workshop etc.. Combine domestic and international the same furnace volume some advanced production operation experience and relevant data of blast furnace also while the design, strive blast furnace should designed to make accomplish highly mechanized , automation and maximizing, in the hope of reaching the best productivity effect.
