The campaign life of blast furnaces can be greatly limited by the interactions of carbon walls with liquid Fe-Csat. Numerous carbon forms have been investigated but not glassy carbon. In this work, liquid Fe-Csat catalyzed the graphitization of glassy carbon crucibles heated in a high-temperature confocal scanning laser microscope. Graphitization created readily wetted pores into which the hot metal penetrated, similar to the embrittlement layer seen in blast furnace hearth refractory.

熔融Fe-Csat催化石墨化玻璃碳

碳壁与液态 Fe-Csat 的相互作用会极大地限制高炉的使用寿命。已经研究了许多碳形式，但没有研究过玻璃碳。在这项工作中，液态 Fe-Csat 催化了在高温共聚焦扫描激光显微镜中加热的玻璃碳坩埚的石墨化。石墨化产生了容易润湿的孔，热金属渗透到其中，类似于高炉炉底耐火材料中的脆化层。
