Abstract：In order to lower melting cost for low carbon steel， RH process parameters were optimized. Carbon oxygen reaction was fully utilized and carbon particles were added to remove partial free oxygen to substitute aluminum to deoxidize. The content of Al2O3 inclusion was reduced and steel cleanliness improved， reducing tonnage steel cost. Through changing pre-vacuuming style and optimizing the operation process of driving gas， splashing was curbed and equipment effectively protected， reducing maintenance cost.
