Abstract：A technology of smelting nitrogen alloyed austenitic steel used for valve by vacuum induction furnace was investigated. The results of repeatedly smelting experiment show that twice carbon-adding during melting can result in the deoxidation of molten steel with oxygen content of (10-15) × 10-6. Supplying of 60%N2 and 40%Ar into vacuum chamber will suppress the escape of nitrogen and manganese from the molten steel efficiently and easy to control the content of nitrogen and manganese precisely. Being added to the molten steel at the end of reducing period after the finish of alloying, the element manganese with N containing will lead to an appropriate content of manganese in the austenitic steel.
