ABSTRACT The production and analysis of highly reactive Fe catalyzed coke through briquetting route were carried out in this work. The utilization of highly reactive coke in steel making is an alternative process to reduce energy consumption and CO2 emissions in a blast furnace. A scale-up approach is carried out by first optimization of parameters in laboratory scale and then implementing those results in the 7 Kg stamp charge coke oven. The experimentation was carried out through the design of experiments by Taguchi method L16 orthogonal array taking five factors with four levels associated with each parameter. Statistical analysis shows that binder percentage has the maximum contribution in the strength of briquette with iron ore percentage having the least effect. Reactivity analysis shows iron ore addition increases the reactivity of coke around 94.9%, indicating a self-reducing property of iron-oxide. CRI and CSR indexes were found to be 52.3% and 3.2%, for 10% addition of iron ore in a blend which shows the increased reactivity of produced coke. Also, this study establishes an important interrelation and validation of results at the laboratory and in the large scale stamp charge oven test.

一种生产高反应性铁矿石催化焦用于高炉操作的放大方法

摘要 本研究通过压块法生产和分析高活性铁催化焦炭。在炼钢中使用高活性焦炭是降低高炉能耗和 CO2 排放的替代工艺。放大方法是通过首先优化实验室规模的参数，然后在 7 Kg 压印焦炉中实施这些结果来进行的。实验是通过田口法L16正交阵列的实验设计进行的，采用五个因素，每个参数有四个水平。统计分析表明，结合剂百分比对型煤强度的贡献最大，铁矿石百分比的影响最小。反应性分析表明，铁矿石的加入使焦炭的反应性提高了 94.9% 左右，表明氧化铁具有自还原性。发现 CRI 和 CSR 指数分别为 52.3% 和 3.2%，对于在混合物中添加 10% 的铁矿石，这表明生产的焦炭的反应性增加。此外，该研究在实验室和大规模印章充电炉测试中建立了重要的相互关系和结果验证。
