摘要
重点介绍了干式粒化工艺中的离心粒化工艺和气淬粒化工艺,由于高炉熔渣的粒化破碎是高温瞬态过程,只通过试验的手段难以监测,因此从试验和数值仿真两方面研究了干式粒化工艺的发展和应用现状.通过对两种工艺的总结和比较,认为气淬粒化工艺具有粒化效果好、处理渣量大等优点,从行业发展和工业化应用的角度来看,是未来匹配大型高炉生产过程最具发展前景的干式粒化工艺.
Abstract
Emphasis was placed on the centrifugal granulation process and gas quenching granulation process during the dry granulation process.Due to the high-temperature transient process of granulation and crushing of blast furnace slag,it is difficult to monitor its specific change process solely through ex-perimental means.Therefore,the development and application status of dry granulation process are studied from both experimental and numerical simulation perspectives.Through the summary and com-parison of the two processes,the gas quenching granulation process has the advantages in good granula-tion effect and large slag handling capacity.From the perspective of industry development and industri-al application,the gas quenching granulation process is the most promising dry granulation process in the future to match large blast furnace production processes.
