ENVIRONMENTAL AND COMMERCIAL SUSTAINABILITY OF BLAST FURNACE SINTER MANUFACTURING

氧化铁烧结矿是高炉高效运行的关键。该博士将研究化学成分，矿物学和微观结构变化如何影响烧结还原和强度，使用最先进的炉模拟和原位和非原位计量。还将研究工艺条件（例如，气体化学、温度、反应器配置），以确定代表Port塔尔博特高炉的具体试验标准。化石燃料替代品也将作为还原剂/燃料进行研究，以调查对烧结和气体排放的影响。该项目将基于斯旺西大学钢铁和金属研究所和塔塔钢铁港塔尔博特内的新Sintec（极端条件下的模拟和完整性测试）设施。该项目还将与免费的EPSRC（例如SUSTAIN）和博士项目联系起来，这些项目也致力于优化未来的可持续钢铁制造。该项目在商业上也很重要。内部烧结生产提供了最大的配料灵活性，因为烧结矿可以按规格生产。因此，优化烧结矿生产的环境和商业可持续性至关重要

Iron oxide sinter is crucial to efficient blast furnace operation. This PhD will study how chemical composition, mineralogical and microstructural variations affect sinter reduction and strength using state-of-the-art furnace simulation and in and ex situ metrology. Process conditions (e.g. gas chemistry, temperature, reactor configuration) will also be investigated to define specific test criteria representative of the Port Talbot blast furnaces. Fossil fuel alternatives will also be investigated as reductants/fuel to investigate the impact on the sinter and on gas emissions.This project will be based between the new Sintec (Simulation and integrity testing under extreme conditions) facility within the Steels and Metals Institute at Swansea University and Tata Steel Port Talbot. The project will also link with complimentary EPSRC (e.g. SUSTAIN) and doctoral projects also working to optimise future sustainable steel manufacturing. The project is also commercially important. In house sinter production provides the maximum burden flexibility since sinter can be manufactured to specification. It is therefore essential to optimise the environmental and commercial sustainability of sinter manufacturing
