烧结矿是日本高炉冶炼的主要原料。目前,在其炉料组分中,烧结矿比例占80%以上。1970至1983年期间日本烧结矿产量见表1。近几年来,日本烧结矿产量有所下降。其间,日本的烧结工艺在从保证提高高炉利用系数方面向促进降低高炉冶炼能耗方面转变,主要是改善烧结矿质量(包括还原特性)和降低高炉涟量。烧结矿的质量决定于许多因素,对各项加以分析研究,进行定最评 Sinter is the main raw material for smelting in Japan. At present, in its charge composition, sinter accounted for more than 80%. The production of sinter in Japan from 1970 to 1983 is shown in Table 1. In recent years, the output of sinter in Japan has declined. In the meantime, the sintering process in Japan has shifted from promoting blast furnace utilization to reducing energy consumption in blast furnaces, mainly by improving sinter quality (including reduction characteristics) and reducing blast furnace ripple. The quality of sinter is determined by many factors, the various analysis and research carried out to determine the most
