influencing coke strength, while the property of coke is essential to maintaining gas and liquid permeability in a blast furnace. Therefore, an in-depth understanding of the pore structure evolution during the graphitization process can reveal the coke size degradation behavior during its descent in a blast furnace. Coke graphitization was simulated at different heating temperatures from 1100 to 1600......
迁钢2号高炉高风温研究陈冠军1,竺维春1,胡雄光1,蔡景春2,倪苹3,杨天钧4(1.北京市首钢技术研究院2.首钢迁钢公司,河北迁安 0644043.首钢国际工程技术公司,北京 1000414.北京科技大学,北京 100083)摘 要:从迁钢2号高炉系统投产运行现状,分析了风温限制环节,从热风炉,热风管道和高炉接受高风温等全面考察了其实现高风温的可行性.通过迁钢2号高炉开展高风温试验,总结分析了实现高风温的具体措施,阐明高风温不仅与热风炉操作紧密关联,而且原燃料,高炉操作等因素直接影响高炉使用高风温.研究结果表明......
