焦炭高温冶金性能的认识及展望
|
摘要
钢铁企业的可持续发展正受到炼焦资源的制约,炼焦资源的合理使用是目前亟待解决的问题。针对目前焦炭的研究中在焦炭的反应性、有害元素对焦炭的影响以及焦炭冶金性能的检测方法等方面存在的问题进行了分析,并概述了高反应性焦炭和废塑料与煤共熄焦的研究现状,提出现阶段的研究重点为:对焦炭在高炉内的反应机理和焦炭在高炉内的粒度变化进行深入的重新认识,对焦炭质量提出合理的要求;根据不同质量的焦炭制定合理的入炉及布料制度;建立一套合理的焦炭检测制度;根据有害元素对焦炭热强度的破坏机理提出有效的防治措施;积极发展新型的炼焦工艺,扩大炼焦可用资源,缓解优质炼焦煤资源紧张的现状。
The sustainable development of iron and steel enterprises is restricted by the coking resources, and the reasonable use of coking resources is a problem to be solved at present. This paper analyzes these problems that exist in the present research of coke reactivity, the effect of harmful elements on metallurgical properties of coke, testing methods and other aspects. The research status of high reactivity coke and waste plastics and coal co-coking are summarized, and the research emphasis are put forward: the reaction mechanism and the change of particle sizes of coke in blast furnace should be re-oriented. Put forward reasonable requests to the quality of coke. According to the different quality of coke, it should make reasonable distributing system. a set of reasonable coke testing system should be founded. According to the damage mechanism of the harmful elements to the coke thermal strength, the effective control measures should be put forward. Enterprise should develop new type of coking process actively, and expand coking resources, to ease the current tense status of high quality coking coal resources.
