1. TL(liquidus arrest) should be here, but was not detected by software. TL this high indicates way too little C% in the melt. Too little C% can also be shown by too short a TE plateau(2).


2. TE (eutectic arrest plateau appears between Si Lo & Si Hi, indicating correct Si% in the melt.



某鑄造廠第一次電爐熔解, 配料有誤.  碳過低. 補了好多增碳劑才拉下到 FC300.  共晶轉折處在Si上下限間 表示Si%  O.K.!
