| Abstract Scope |
In this study, a damage investigation was carried out on a blast furnace using hydrogen-rich gas smelting. During the period, a green-white phase with a thickness of 150mm-200mm was found inside the carbon composite brick in the taphole area. The carbon bricks in this area were sampled, and XRD, chemical analysis, and SEM-EDS detection were carried out. The test results show that there are blast furnace slag erosion and harmful element Zn erosion in carbon composite bricks. The erosion of harmful elements caused the expansion and ring cracking of carbon composite bricks, resulting in further slag erosion, which eventually led to the macroscopic slag phase erosion in the taphole area. |
