Metallographic analysis of HT150 gray iron castings directly produced by water slag iron smelting

The morphology of HT150 gray iron castings produced by direct ironmaking with water slag iron under scanning electron microscope is shown in the figure. From figure (c), we can see that in the 1000 times microstructure, there are three phases in the gray iron casting: ferrite, pearlite and cementite (the existing form of graphite in gray iron HT150).

a, B and C respectively show the metallographic morphology of HT150 gray iron castings produced by water slag iron under different magnification
Figure (d) shows the microstructure of standard HT150 under metallographic microscope,
Figure (E) shows the microstructure of HT150 produced by water slag iron ironmaking under metallographic microscope

The picture shows the comparison of metallographic microstructure between standard brand HT150 and HT150 produced by water slag iron smelting. Through comparison, we can know that the morphology of gray iron castings (HT150) produced by water slag iron smelting is similar to that of standard gray iron (HT150) materials, and the metallographic structure is completely consistent.
