1、A，1，HIsmelt熔融还原技术smellt reduction technology-his melt reporter:jalijun presenter 3360 Jia Lijun，A，2，内容内容报告，内容报告as one of the commercial ized smellt reduction iron-making technology，His melt has evolved to a mature solution after thirty years of research afterhis melt炼铁工艺技术是利用郑智薰焦煤和铁矿粉喷射生产液态铁，是解决我国煤炭

2、资源贫乏环境问题的先进炼铁技术。his melt uses non-coking col and iron ore fines，which offers a solution to the coking coking cool scarcity and environmental problem in chhhis melt炼铁工序在澳大利亚奎拿纳工厂，从2005年到2008年，有3年的生产实践。他的梅尔特技术上的优势吸引了受世界金融危机影响的全球钢铁行业的目光，他的梅特奎纳斯示范工厂于2008年底停产，没有重生。his melt kwin ana plant in Australia had

3、 run fours years from 2005 to 2008 and it successfully demonstrated the advantage of this technology。it was fo Rced to shut down due to global economic crisis。国内某公司自2004年以来致力于对新的钢铁工艺、技术和设备的研究，2012年决定利用部分HIsmelt quinata工厂设备，进一步优化工艺流程，建设了新的HIsmelt熔融还原钢铁厂。A Chinese company，who has been focususing on th

4、e research of innovative iron-making technology，process and equipment，Decided to buipmentthis plant uses some of the kwin ana equipment，But also makes some modification by optimizing the existing Process，A，4，1.2 his mequipmentiron-bearing material is reduced to liquid iron mai石头和灰色从矿石和煤中分离，形成渣；刚和灰从o

5、re and cool form slag工艺反应引起的气体和热风的二次燃烧产生热。process gas combusst with hot blast to produce energy渣和铁水液体将能量导入熔池以保持反应。metal and slag droplet bring part of the energy back to the bath to sustain the reaction，SRV熔融还原炉产生的反应如下：Reaction in the SRV:A，6，1.3 HIsmelt流程his melt process flow，iron ore，doomite，dryer

6、，pre-reduction kill his melt工艺技术优势Advantages of HIsmelt，低投资成本：与现有炼铁技术相比，Lower capital cost compared with traditional blast furnce due to 3360 his melt使用焦炉和烧结His melt eliminates coke oven、sinter plant and pellet plant his melt流程的很多设备和设施，例如热风炉、喷煤系统、发电等是高炉炼铁流程中常用的设施，因此工厂建设相对简单，但HIsmelt sharks many comm

7、onhis melt technology使用的原料比较灵活，因此无需大型原料混合场就大大减少了his melt工厂的占地面积。his melt is flexible in raw materials selection and no blending facility is needed，a，8，2 his melt工艺技术优势Advantages of HIsmelt，低运营成本his melt uses iron ore fines and cool directly；No coke，sinter or pellet will be needed，a，9，更大的原料灵活性great f

8、lexibility in raw material:his melt技术直接从传统高露烧结厂注入不合格的低品位铁矿石粉。his melt can use low grade iron ore fines which otherwise can not be used by the blast furnce sinter plant，a，10，铁水质量稳定，含量低，基本上不含硅，因此减少了炉渣Stable hot metal quality、low p content、almost no siliconso less slag is need in the steel mill and thu

9、s reducing steel mill cost，him SELT工艺与高炉生产铁水成分比较HIsmelt Hot Metal vs. BF Hot Metal，铁水质量好Superior hot metalAlmost no emission of dioxins，phenols or tars due to the revolutionary process and elimination of coking oven and sintering process。介绍更环保的炼铁技术Less Environmental Impact，A，12，3生产情况Production Exper
