我厂自从1951年建厂以来,厂内积存了很多粉矿。为了利用这些资源,1957年开始建立烧结生产设备,经过几年来的生产实践,在生产高碱度烧结矿方面,获得了显著的成效。烧结矿碱度(cao/sio_2)由以往的1.0～1.10提高到1.76,其化学成分见表1,高炉由于大量使用高碱度烧结矿,入炉石灰石由去年10月份的470公斤/吨铁降低到11月份的270公斤/吨铁,12月上旬再降低到198公斤/吨铁(10月份烧结矿使用率为33.3%,11月份44.6%,12月上旬为50%),高炉焦比也有显著降低,与此同时由于烧
Since our plant was established in 1951, a lot of powder ore has been deposited in the factory. In order to utilize these resources, the establishment of sintering production facilities began in 1957 and, after several years of production practice, has yielded remarkable results in the production of high basicity sinter. The basicity of the sinter (cao / sio_2) increased from 1.0 to 1.10 in the past to 1.76. The chemical composition of the sinter is shown in Table 1. In the blast furnace, due to extensive use of high-basicity sinter, limestone input decreased from 470 kg / t iron in October last year The 270 kg / tonne iron in November was further reduced to 198 kg / tonne iron in early December (33.3% in October, 44.6% in November and 50% in early December), and the blast furnace coke ratio was also significant Reduce at the same time as a result of burning
