| 摘 要： | 影响溅渣护炉效果的终渣成分的控制，主要是控制终渣中ＦｅＯ％、ＭｇＯ％和Ｒ。通过试验室小型热态模拟实验，测定了溅渣的侵蚀量，炉渣半球熔点，并分析炉渣的显微结构，探讨了溅渣层的侵蚀机理，提出了溅渣护炉的终渣成分大致分别为ＭｇＯ＝８％－１０％，ＦｅＯ＝１０％－１３％，Ｒ＝３．５左右。

| Abstract: | Controlling the composition of final slags is a key factor to effect slag splashing, es-peially controlling the contents of FeO%'Mgh% and R in final slags. Through some small thermalsimulation experiments in laboratory, corrosion degree of splashing slag layer and hemiasperical melt-ing point have been measured. The microstructure of slag has been analyzed and the corrosion mech-anism of splashing slag layer has been also discussed. Finally, it is put forward that content of MgOin final slop is forut 8%~10%,FeO about 10%~13% and R=3.5. |
