By means of optical microscope and scanning electron microscope,Ti elements has good effect on grain refinement in the low carbon cast steel, but the content of Ti elements is unfavorable and exorbitant,the Mg-deoxidizing products can't induced intra-granular ferrite,but the sample steel which joins Mg element can reduce the number of Al-oxide,in addition, Mn-Ti,Mn-Ti-Al,Mn-Mg-Ti-Al composite inclusions can be the core of induceing intra-granular ferrite, the nucleation effect of TiN is not obvious, the inclusion which contain high Al element content can not adsorpt MnS,so the effect of nucleation is not ideal, the individual MnS can not have the effect on grain refining. At the same time, it found that MnS plays a vital role on grain refinement,and the inclusions only can adsorpt MnS to format the complex inclusions ,which can be the core of the intra-granular ferrite.

Titanium works well in grain refinement of the low carbon cast steel via characterization of optical microscope and scanning electron microscope, except that the content of titanium is exorbitant and unfavorable. Mg-deoxided products can¡¯t induce intra-granular ferrite, but the sample steel which joins Mg element can reduce the number of Al-oxide. In addition, composite inclusions of Mn-Ti, or Mn-Ti-Al or Mn-Mg-Ti-Al can be the core of inducing intra-granular ferrite. The nucleation effect of TiN is not obvious, the inclusion which contains high content in Al element can not absorb MnS, which results in unfavorable nucleation. MnS alone displays bad effect on grain refining. However, it¡¯s found that MnS plays a vital role on grain refinement, and the inclusions only can absorb MnS to form the complex inclusions, which can be the core of the intra-granular ferrite.
