【摘要】 热压含碳球团是一种利用煤的热塑性来提高强度的新型炼铁原料。在实验室条件下,本文对碱度1.2 和 FC/O 比1.0的未热处理和热处理热压含碳球团,分别检验其低温还原粉化、还原膨胀、还原冷却后强度等高温特性,并与其它炼铁原料进行合理对比。实验室研究结果表明,热压含碳球团的高温冶金性能优于普通球团矿或烧结矿,适用于炼铁生产。更多还原

【Abstract】 The carbon composite iron ore hot briquette (CCB) is a new type of iron-making material,which utilizes thermal plasticity of coal for enhancing its high-temperature strength.Under the experimental condition,the experiments choose both heat-treated and non heat-treated CCB with proper basicity (1.2) and FC/O (1.0).and than, investigate its reduction-dusting property under lower temperature,reduction-swelling property,and low-temperature strength after reduction;at last,compare these to other iron-making materials.The experimental results show that,the high temperature properties of CCB are better than that of common oxidized pellet or sinter,which is able to be utilized as ironmaking burdens.更多还原
