Abstract—

The technology of producing and applying magnesian agglomerate with the Bakal concentrate of burnt siderite ore (CBSO) used in the batch mixture is considered. According to lab tests on a sintering pot plant, an increase in the CBSO content in the sinter burden of the Vysokaya Gora Mining and Processing Works (VG MPW) increases the nodulizing degree and the vertical caking rate. Intensified caking was observed in the industrial experiment, including the replacement with CBSO of an ore mixture part based on the concentrate from the Bogoslovskoe mine group (MG). The influence of magnesian agglomerates on the performance levels of the blast furnaces of Novolipetsk steel is studied. It is established that the replacement of the common agglomerate from the VG MPW with its magnesian counterpart, pellets from the Mikhailovskii MPW included (20 to 30%), has allowed cutting the consumption of coke and crude lime stone, reducing the basicity of the slag, and increasing the manganese content in the cast iron.

在高炉中使用镁烧结铁冶炼炼铁

摘要-

考虑使用批料混合物中使用的烧过的菱铁矿矿石的巴卡勒精矿（CBSO）生产和应用镁质团聚体的技术。根据对烧结锅厂的实验室测试，Vysokaya Gora采矿和加工厂（VG MPW）的烧结料中CBSO含量的增加增加了结瘤度和垂直结块率。在工业实验中观察到结块加剧，包括以Bogoslovskoe矿业集团（MG）的精矿为基础的矿石混合物部分的CBSO替代。研究了镁矿团聚体对新利佩茨克钢高炉性能水平的影响。可以确定的是，将VG MPW的普通附聚物用其镁合金代替，其中包括Mikhailovskii MPW的颗粒（占20％至30％），
