The effect of Ca-Si and FeS adding order in Ca-treatment process and Ca/S ratio for steel on morphology and quality of sulphide in 0.048%~0.065% S medium-carbon steel(0.46~0.57C
0.83~0.94Mn
0.21~0.24Cr
0.03~0.04Mo)has been studied by a carbon tube fumnace in laboratory.the results showed that the length and quantity of sulphide in steel by treatment first adding FeS then adding Ca-Si were obviously lower than that first adding Ca-Si then adding FeS;and with increasing Ca/S ratio in steel
the quantity of spherical multi-phase inclusions increased while the quantity of strip-shapc MnS decreased
of which the size increased. The available Ca/S ratio for steel by compound treatment using Ca-Si is ~0.03.
