摘要

为了提高冲天炉中焦炭的性能，作者发现高炉中使用的焦炭[焦炭反应指数（CRI）低，反应后焦炭强度（CSR）高]比铸造焦炭的强度更高，而且由于到达熔化区的焦炭块更大，因此性能可能更好。冲天炉中焦炭的强度和尺寸极为重要，因为焦炭必须完整地到达熔化区，在熔化区停留足够长的时间以补充焦炭床，为熔化提供热量，并为铁液提供碳。本研究评估了高 CRI 和低 CRI 焦炭冲天炉性能的差异。此外，还努力确定这些焦炭的特性差异。

Low CRI, High CSR Coke Trials

To improve coke performance in the cupola, the authors discovered that coke used in blast furnaces [low coke reactivity index (CRI), high coke strength after reaction (CSR)] exhibits higher strength than foundry coke and may provide better performance due to larger coke pieces reaching the melt zone. Coke strength and sizing are extremely important in a cupola because the coke must reach the melt zone intact, stay in the melt zone long enough to replenish the coke bed, provide heat for melting and carbon pickup to the liquid iron. This research evaluates the cupola performance difference between cokes of high and low CRI. In addition, efforts were made to identify differences in characteristics of these cokes.

期刊介绍： The International Journal of Metalcasting is dedicated to leading the transfer of research and technology for the global metalcasting industry. The quarterly publication keeps the latest developments in metalcasting research and technology in front of the scientific leaders in our global industry throughout the year. All papers published in the the journal are approved after a rigorous peer review process. The editorial peer review board represents three international metalcasting groups: academia (metalcasting professors), science and research (personnel from national labs, research and scientific institutions), and industry (leading technical personnel from metalcasting facilities).
