In the paper, the key control and smelting process in each procedure of steel making for wheel steel with rare earth are introduced. The stable control for the yield of rare earth in steel and pourability of casting machine is realized with different controls of steel making process. Such procedures as KR desulfurization process, end point of converter, steel tapping, LF and RH refining process and casting in steel making are strictly controlled combining with the characteristics of deoxidation and desulfurization for rare earth elements to increase the yield of rare earth elements in steel. As a result, the yield of rare earth elements is guaranteed to be stably controlled at 38%~40% so that the production control for wheel steel with rare earth in steel making is completed.
