摘要
采用PoDFA法离线测渣仪对某7×××铝合金保温炉出口、在线除气装置出口、过滤装置出口熔体取样进行离线测渣,确定了夹渣物含量及夹渣物种类,并对夹渣物的来源进行了分析。结果表明:该7×××铝合金中典型夹渣物为氧化铝、氧化镁、冶金学尖晶石,夹渣物经在线除气装置处理后有所减少,经过滤装置处理后除渣效果显著。
A certain 7×××-aluminum-alloy slag samples from the outlet of the holding furnace,the online degasser and the filter were measured with the off-line slag analyzer based on the PoDFA method.The slag content and type were determined and the source was analyzed.The results show that the slags typically contain alumina,magnesium oxide,metallurgical spinel and decrease grain refiner.Slags decrease slightly after degassing and greatly after filtering.
