摘要
在国家倡导“碳达峰”和“碳中和”背景下,钢铁工业亟待研发和应用绿色低碳前沿技术,当前氢冶金技术是钢铁工业发展的重要方向,受到国内外广泛关注。氢冶金是一种新型的冶金技术,利用氢气作为还原剂,可以实现高效、环保和节能的冶金过程。近年来,微波技术作为一种新型加热手段,被广泛应用到冶金领域,具有加速还原反应、提高冶金效率、清洁环保等显著特点。基于氢冶金技术和微波技术优势,从“碳-电-氢”的三元关系角度审视炼铁能源结构,提出一种将微波和氢气相结合的新型还原方法——“微波-氢气协同还原”。该方法具有更高的反应速率和更低的温度要求,可以实现对反应过程的精确控制和优化,有望成为氢冶金领域的重要技术之一。在“双碳”战略目标下,结合国内钢铁碳排放现状,首先综述了国内外氢冶金技术的研究进展,主要包括高炉富氢还原、富氢气基还原、富氢熔融还原和等离子体氢还原;分析了微波技术在冶金熔炼领域的应用现状和作用机理;其次着重介绍了微波-氢气协同还原新方法的研究进展以及发展过程中存在的一些问题,为氢冶金技术的发展提供新思路;最后探讨了微波-氢气协同还原新方法未来在氢冶金领域中应用的潜在价值,为推动还原新方法的发展提出远景展望。
Under the background of"carbon peaking"and"carbon neutrality"advocated by the state,the steel industry urgently needs to develop and apply green and low-carbon frontier technology,and the current hydrogen metallurgy technology is an important direction for the development of the steel industry,which has received extensive attention at home and abroad.Hydrogen metallurgy is a new type of metallurgical technology,using hydrogen as a reducing agent,which can achieve an efficient,environmentally friendly and energy-saving metallurgical process.In recent years,microwave technology,as a new heating method,has been widely used in the field of metallurgy,with significant characteristics such as accelerating the reduction reaction,improving metallurgical efficiency,and cleaning and environmental protection.Based on the advantages of hydrogen metallurgy technology and microwave technology to examine the energy structure of ironmaking from the perspective of the ternary relationship of"carbon-electricity-hydrogen",and proposes a new reduction method combining microwave and hydrogen-"microwave-hydrogen co-reduction",which has higher reaction rate and lower temperature requirements,can achieve precise control and optimization of the reaction process,and is expected to become one of the important technologies in the field of hydrogen metallurgy.Under the strategic goal of"dual carbon",combined with the current situation of domestic steel carbon emissions,the research progress of hydrogen metallurgy technology at home and abroad is first reviewed,mainly including blast furnace hydrogen-rich reduction,hydrogen-rich base reduction,hydrogen-rich fusion reduction and plasma hydrogen reduction.The application status and mechanism of microwave technology in the field of metallurgical melting were analyzed.Secondly,the research progress of new microwave-hydrogen co-reduction methods and some problems in the development process are introduced,which provides new ideas for the development of hydrogen metallurgy technology.Finally,the potential value of the new microwave-hydrogen co-reduction method in the field of hydrogen metallurgy in the future is discussed,and the long-term prospect is put forward for promoting the development of the new reduction method.
