一九七一年我厂开始生产土烧结矿。其特点是:高 SiO_2、高 MgO、低碱度(自然碱度,R_2=CaO/SiO_2≈0.3)、高强度。因碱度低,氧化亚铁高,还原性差,未能充分体现出熟料的优越性。78年四月份开始,我们试生产较高碱度、高 MgO 的烧结矿。经过几个月的生产实践,终于生产出 R_3=(CaO+MgO)/SiO_2=1.6,R=1.05～1.10,MgO≈6.5%的烧结矿,我们称它为高 MgO 自熔性烧结矿,文中简称高 MgO烧结矿。随着高 MgO 烧结矿的应用,高炉各项
In 1981, our factory began to produce soil sinter. Its features are: high SiO 2, high MgO, low alkalinity (natural alkalinity, R_2 = CaO / SiO_2 ≈ 0.3), high strength. Due to low alkalinity, high ferrous oxide, poor reduction, failed to fully reflect the superiority of clinker. Since April 78, we piloted the production of high basicity, high MgO sinter. After several months of production practice, we finally produce sintered ores of R_3 = (CaO + MgO) /SiO_2=1.6,R=1.05~1.10,MgO≈6.5%, which we call high-MgO self-fluxing sinter. Referred to as high-MgO sinter. With the application of high MgO sinter, various blast furnaces
