摘　　要：镁尖晶石浇注料经坩埚法抗渣后 ,残存试样可以分为四个段带 ,即挂渣层、侵蚀层、铁渗透层和硅酸盐相富集层。本实验采用SEM和EDAX研究了各段带的显微结构和基质组成 ,讨论了转炉终渣对浇注料的侵蚀过程和机理。The residual specimens of MgO spinel castables after BOF slag corrosion test at 1600℃ by crucible method may be divided into four zones-slag adhesion, corrosion, ferrite penetration and silicate concentration zones. The changes in the microstructure and matrix composition of every zone have been investigated by using SEM and EDAX.Also the process and mechanism of slag corrosion have been discussed.
