通过对涟钢90t顶底复吹转炉炉渣试验数据进行分析,结果表明:为了获得最佳的炉渣脱磷效果,炉渣碱度应控制在4.6左右,炉渣中w((FeO))控制在16%左右,炉温则控制在1680℃左右;通过对炉渣实际组成在CaO(MgO)-SiO2-FeO(MnO)伪三元相图中的变化途径与常见的转炉渣成渣路线进行比较发现,涟钢顶底复吹转炉冶炼造渣操作遵循的是ABC途径,即低氧化铁成渣路线,该路线主要适用于含磷、硫较低的生铁炼钢,通过分析讨论该成渣路线的利弊,提出一些优化该厂造渣工艺的建议。 相似文献

The steel slag in the decarburization converter is treated by the little water-spreading (LWS) and the heat-stewed (HS) methods, which is used as the furnace burden of the dephosphorization converter. The slag characteristics by the LWS and the HS methods and its application effects as the furnace burden are researched. The results show the moisture content in the HS slag is higher than that of the LWS slag. There is higher total iron content in the HS and the LWS slags and almost same melting point. The dicalcium silicate content in the LWS slag is higher than that in the HS slag. The tricalcium silicate in the LWS slag is lower than that in the HS slag. There are a lot of calcium ferrite in the LWS and the HS slags, which is beneficial to dephosphorization and slag melting. The LWS and the HS slags are added to dephosphorization converter each charge by 3 or 6 t. The results show that the saving lime is 0. 7-1. 0 t for each charge. The petrographic constitute of final slag for the dephosphorization converter by adding the LWS and the HS slags is dicalcium silicate, RO phase and glass phase. There are a little calcium ferrite phase in the LWS slag, which is helpful to dephosphorization. So there are better dephosphorization effects for the LWS and HS slags. 相似文献
