Abstract：Based on the thermodynamic calculating,a model of[C][0]at the converter finishing point is established.According to the calculating model,the average relative error compare with the practical results is 1.24％.By the calculating,the optimum of the aluminium content in GCr15 at the finishing point of the converter is 0.253 6％,and the corresponding of the oxygen content is 1.58 ppm.Also the[Al]and[0]reaction balance model at 1 500 ℃ is established.The calculating results is that there is a large difference between the oxygen content at 1 500 ℃ and 1 600 ℃.To better control the[O]in the GCr15 bearing steel,to reduce the highest temperature during the production process is necessary.In order to obtain a good results of the oxygen content and the grain refining in GCr15 bearing steel,it is better to control the content of the[Al]between 0.012％and 0.018％.
