| 摘 要： | 由于对天然块矿的冶金性能认识不够全面和深入,影响了现代高炉使用块矿技术的发展.通过分析和实验,考察了世界主要产地的块矿的各种冶金性能.结果表明:天然块矿除自身软熔特性较差外,其他冶金性能均能满足现代高炉冶炼的要求;在高炉高温区块矿会与烧结矿发生交互反应,能够明显改善块矿自身的软熔特性,且可利用这一交互反应性优化块矿搭配模式.

| Abstract: | The fact that the metallurgical properties of natural lump ores were not insufficiently comprehensive and thorough grasped is obstructing the technology development of using lump ores in a modern blast furnace. Through analyzing and inspecting each metallurgical property of natural lump ores from main habitats in the world by experiment, the article indicates that the lump ores' metallurgical properties can meet a modern blast-furnace except the softening and melting properties. And the interaction between the sinter and the lump ores was found in the high temperature zone of the blast furnace, which can obviously improve the softening and melting properties of the lump ores. The blast burden structure also can be optimized by the interaction. |
