| Abstract: | The CCr15 bearing steel is produced by a 90 t EBT arc furnace-LF(VD)-240 mm×240 mm billet concasting process at Beiman Special Steel. The statistic results showed that with using 4.46 high basicity slag series,deoxidant containing 32.8% Al,VD vacuum treatment for 25 min and controlling [Als]≤0.030%,the oxygen content in GCr15 bearing steel was ≤8×10-6 |
