In order to increase the output of sinter and improve its quality with achieving the target of energy-saving and consumption-reducing, the new method of optimizing the ore proportioning for sintering was innovatively proposed and as a result the process by application of intelligent ore-proportioning was achieved instead of the traditional process in Ansteel. And also the improper production processes for pelletizing during sintering was corrected so that the massive technical transformation on the processes for pelletizing during sintering by one cylindrical granulator instead of sixteen disc granulators was fulfilled, which can provide the valuable basic data for China to choose the granulating equipment for sintering in the future. In addition the new method to optimize the particle-size composition of fuels to be sintered was innovatively proposed by the single-type lattice method based on statistical mathematics. For the first time it was proposed not to use the magnesia flux during sintering to achieve the operation of BF with low content of magnesium oxide in slag. Finally the suitable technological parameter for sintering process and the basicity of sinter as well as the proper content of ferrous oxide were determined. Based on above research results the new sintering process with super thick-bed of materials was developed and thus the key scientific research which should be carried out in the field of iron-making materials in Ansteel was put forward.%围绕提高烧结矿产量、质量，节能降耗，创新性地提出烧结配矿优化新方法，实现了鞍钢由传统配矿到智能配矿的转变；纠正了不合理的烧结制粒工序，实现烧结制粒工序由1台圆筒制粒机替代16台圆盘制粒机的大型技术改造，为今后我国烧结制粒设备的选择提供了宝贵的基础数据；创新性地提出用统计数学的“单型格子法”优化烧结燃料粒度组成的新方法；首次提出烧结不配加氧化镁熔剂，高炉实现低氧化镁炉渣操作；确定了合理烧结工艺参数及烧结矿碱度、合理氧化亚铁含量等；开发了超厚料层烧结工艺新技术，提出了鞍钢在炼铁原料技术方面应开展的重点科研工作。
