摘 要：<正> The oxidation of alloying elements duringthe ESR of stainless steel has been studied.The model previously developed by WEI and Mitchellfor the chemical reactions and mass transferprocesses during ESR was applied to the remeltingof the high Cr steel 1Cr18Ni9（Ti）.The laboratorydata for the unsteady state A.C.ESR were analyzedand dealt with by the model.When the remeltingprocess reached a steady state,an oxidant（Fe2O3powder）or a deoxidant（Ca-Si powder or metallicCa）was added to the slag bath.The resultsshowed that this model is applicable to theremelting of stainless steel rather precisely,and it is expected that the model may offera reliable basis for the control of compositionduring practical ESR of high alloy steel.Also,the oxidation of Cr in the steel mustbe noticed when its content is high;but itis entirely possible to adjust the Cr contentof ingot within a considerable range,usinga special technique by means of the slag-metalreactions during the remelting.
