摘要
近年来,高炉对焦炭质量要求越来越高,提高焦炭冷热态强度即焦炭致密性愈发重要。首先研究影响焦炭质量的因素:配合煤的堆密度,论述提高配合煤堆密度的现有方法应用及缺点。介绍煤压实工艺,详细了解煤压实工艺在改善焦炭强度中的作用。通过对比试验验证煤压实对焦炭质量的影响,确定了最佳煤压实工艺并设计实际生产试验方案。通过实际生产试验,介绍了配合煤运转流程、压实机布置方案及试验结果、环境除尘方案及效果。介绍了生产过程中的参数检测和控制,并对生产效果进行了验证。基于此,分析试验技术经济,得出煤压实工艺在提高焦炭质量方面有极大推广价值。煤压实工艺能够提高焦炭致密性,满足高炉生产需要。同时,通过在焦炉中煤压实工艺的践,验证了煤压实工艺对提高焦炭冷热态强度的作用。
In recent years,the blast furnace has higher and higher requirements for coke quality,and it is increasingly important to improve the cold and hot strength of coke,that is,the compactness of coke.In order to study how to improve the quality of coke,first of all,the factors affecting the quality of coke-the bulk density of blended coal were studied,and the application and disadvantages of existing methods to improve the bulk density of blended coal are discussed.The coal compaction technology,and details the role of coal compaction technology in improving coke strength were intruduced.The influence of coal compaction on coke quality is verified through comparative tests,and the best coal compaction process is determined and the actual production test scheme is designed.Through the actual production test.The combined coal transportation process,compactor layout plan and test results,environmental dust removal plan and effect were intruduced.The parameter detection and control in the production process are introduced,and the production effect is verified.Based on this,the test technology and economy are analyzed,and it was concluded that coal compaction technology has great promotion value in improving coke quality.Coal compaction technology can improve the compactness of coke and meet the needs of blast furnace production.At the same time,through the practice of middling coal compaction process in coke oven,the effect of coal compaction process on improving coke cold and hot strength is verified.
