【摘要】 对安钢6号高炉降低焦比的技术攻关进行了总结。通过分析影响因素,更新操作理念,采取改善入炉原燃料质量;大矿批、全正装、灵活布料、高风温、高煤比、高氧量;合适的低[S]低[S]冶炼;强化出铁出渣管理等措施,使6号高炉在2007年3月焦比达到358kg/t,比去年同期降低45kg/t。更多还原

【Abstract】 Technology tackling of reducing coke ratio on Anyang Steel’s No.6 BF is summarized.By means of analysing influence factor,the renewal operation idea,a few measures are taken,such as improving the material;adopting large ore batch charging,complete forward direction,agileburden distribution,high blast temperature,high pulverized coal injection rate,high oxygen-enrichment;appropriate low low [S] smelting;strengthening management on tapping and slagging.etc.As a result,coke ratio achieves 358 kg/tin march of 2007,lowers 45kg/t than the same period of last year.更多还原
