| 摘 要： | 通过对用后氧化锆水口砖的显微结构及矿相分析,认为氧化锆水口砖的损毁主要是由于钢水和渣的侵蚀造成氧化锆中的稳定剂脱溶失稳分解产生的,同时由于热应力产生的微裂纹导致钢水的进一步渗透,加快了水口的侵蚀速度.

| Abstract: | Based on analysis to micro structure and mine phase of used zirconia nozzle brick,it is considered that damage of the brick is because of the stabilizer in zirconia getting precipitated,instable and decomposed caused by corrosion of molten steel and slag,and furthermore the corrosion is speeded up by the more permeation of steel through the micro cracks brought by thermal stress. |
