1、130t氧气顶吹转炉的设计湖南化工职业技术学院毕??业??论??文题目:130t氧气顶吹转炉的设计院系名称:制药与生物工程系专业班级:冶金技术学生姓名:汪成贤学号:201103031116指导老师:曹慧君7>2013年11月20日摘要转炉炼钢是以铁水、废钢、铁合金为主要原料,不借助外加能源,靠铁液本身的物理热和铁液组分间化学反应产生热量而在转炉中完成炼钢过程。转炉按耐火材料分为酸性和碱性,按气体吹入炉内的部位有顶吹、底吹和侧吹;按气体种类为分空气转炉和氧气转炉。碱性氧气顶吹和顶底复吹转炉由于其生产速度快、产量大,单
2、炉产量高、成本低、投资少,为目前使用最普遍的炼钢设备。本次设计针对130T氧气顶吹转炉主体设备进行,阐述了130T氧气顶吹转炉主体设备的发展历史、结构原理、经济技术指标、设计特点和转炉炼钢设备的优缺点,并且查阅了国内、国外部分厂家的先进经验,对包括工艺、设备组成、原理、相关理论等项内容进行了比较,对炼钢工艺、原料成分、物料平衡、热平衡、选择炉型进行的计算,炉型主要尺寸的确定,经过计算画出相应的炉型。本设计主要是为了锻炼我们查找资料、团队合作和相应的计算能力。关键词:氧气顶吹转炉,冶金,氧枪。Title:Top-bl
