摘　　要：对新钢2 500 m^3高炉炼铁和对应的烧结工序的锌平衡情况进行研究,结果表明:进入高炉的锌量为1.055 kg/t,主要由烧结矿和球团矿带入,其中烧结矿带入的锌量占总量的84%,高炉锌主要由布袋灰排出(占总排出量的89%);烧结工序中,带入的锌量为1.162 kg/t,主要来源于混匀料、内部冷返矿和除尘灰(占总量的97.47%),锌的排出由烧结矿和返矿带出(占总排出量的95.92%)。结合新钢生产实际情况,提出了在烧结、炼铁工序中减少锌带入量、加大锌排出量的建议。The zinc balance of 2 500 m^3 BF ironmaking and corresponding sintering process is studied in Xinyu Steel. Results show that the amount of zinc into the blast furnace of 1. 055 kg/t,is mainly composed of sinter and pellet among then,the sinter carries 84% of the total amount of zinc. Zinc blast furnace is mainly discharged through bag dust（ accounting for 89% of the total discharge）.IN 1. 162 kg/t zinc is carried in sintering process,mainly comes from blending materials,internal cold back to mine and dust（ accounting for 97. 47% of the total）,discharged by the sinter and recovery of zinc ore（ accounting for 95. 92% of the total discharge）. According to the actual production situation in Xinyu Steel,the measures to reduce the amount of zinc and increase the amount of zinc are put forward.
