| Abstract: | Through the pouring process of the mock-up ingot mold under the condition of 800℃ heating,2 hours holding and air cooling,the cold and heat fatigue microstructure of two kinds of materials ingot mold with 10 to 40 times heating and cold heating circulation has been measured as well as the variation of the ferrite contents and the thickness of decarburized layer,so that the optimized composition of the medium Mn and low Si ingot mold,the ratio of Mn/Si and the related microstructures have determined as well. |

| Keywords: | ferrite medium Mn and low Si steel ingot mold pearlite |
