Abstract: The effect of vacuum,refining slag,argon stirring process and [Al]s on oxygen content in steel has been analyzed and studied in production of Mn-Cr,Cr-Mo and Cr-Ni-Mo series new type gear steels for car by 30 t EBT are furnace-40 t LFV refining process to get that it is available to obtain lower oxygen content in steel by the operation with vacuum less than 1.33 kPa,100~150L/min Ar stirring,refining slag basicity 2.5~3.0 and controlling [Al]s between 0.02% and 0.04%.The production results showed that the oxygen content in Mn-Cr,Cr-Mo and Cr-Ni-Mo series gear steels was between 12×10-6 and 20×10-6 up to standard requirement for oxygen content in new type gear steels for car.
