日本低成本和环境友好型炼焦新技术的进展

针对日本新近研发的新一代炼焦技术:SCOPE21、全部使用弱、非黏结煤生产焦炭技术以及高反应性焦炭生产技术进行了阐述。重点介绍了这三种技术的研发背景、特点以及目前的研究状况和工业化应用情况。这三种技术的开发对于提高弱、非黏结煤的用量,降低生产成本都具有十分重大的意义。SCOPE21是日本由于面临焦炉逐渐老化问题而开发出来的新一代炼焦技术,已在新日铁大分厂投入了工业化应用;在全部使用弱、非黏结煤生产焦炭方面,针对通过制备Hyper煤来全部使用弱、非黏结煤生产焦炭的可行性进行了研究,得出了Hyper煤是生产高强度焦炭的有效添加剂这一结论;高反应性焦炭生产技术分为"预添加法"和"后添加法"。已有关于对高反应性焦炭用于高炉的可行性分析研究。

Develoment progress of low-cost and environment-friendly new coking technology in Japan

This paper introduces new coking technologies in Japan,including the new-generation coking techonology SCOPE 21,the coke production technology completely from weakly or non-caking coal and the production technology of highly reactive coke,focusing on the research & development background,technology features and current research status and commercial application of those three techonologies. The development of those technologies is of great importance to the increase of usage of weakly or non-caking coal as ...
