摘　　要：焦炭是高炉炼铁最重要的原燃料,其性质直接关系到高炉冶炼的效率和成本。焦炭的热性质备受炼焦和高炉炼铁领域关注,各国研究者根据对焦炭溶损反应的试验研究结果,相继提出了新的方法来测试和评价焦炭的热性质,获得简捷而实用的焦炭热性质指标对高炉生产至关重要。总结了当前对焦炭溶损反应行为以及焦炭热性质评价方法的研究进展,归纳了各种焦炭热性质评价方法的特点,提出了关于焦炭反应行为和焦炭性质评价方法的一些新思路和研究方向。Coke is one of the most important raw materials for blast furnace ironmaking. The property of coke is related to the efficiency and cost of blast furnace process directly. The thermal property of coke has become a rising concern in the coking and iron making industry. New methods were proposed to test the thermal properties of coke constantly based on the experimental results. It is important to obtain a simple and practical coke thermal property index for blast furnace production. The work reviews some progresses in reaction behavior of coke in blast furnace and evaluation methods of coke thermal property. The characteristics of coke thermal property evaluation methods were summarized. Some new ideas and research directions about coke reaction behavior and coke property evaluation were also proposed.
