摘　　要：针对宝钢COREX-3000建立COREX工艺模型,研究了COREX工艺模型在计算功能、原燃料配比优化及结果分析方面的应用.研究了金属化率、氧化度、荒煤气温度对煤耗、氧耗和煤气量的影响;通过对熔化气化炉热平衡分析,了解热量的收入与支出项;通过对还原煤气气体成分的分析图,判断该气体成分能否满足竖炉的需求,通过调整操作参数更新还原煤气的煤气成分.在荒煤气氧化度为7%、温度为1050℃的条件下,煤耗、氧耗随着金属化率升高显著降低,当金属化率为85%时,氧耗为520m^3/t,煤耗为976kg/t.The COREX process model was established for COREX-3000 of Baosteel,and the application of COREX process model in calculation function,original fuel ratio optimized and results analysis were described.The influences of different metallization,different oxidation and different gas temperatures on coal and oxygen consumption were studied.And the input and output items of heat were also studied based on heat balance.Through reduction gas composition analysis picture,it could be judged whether or not met the nee...
