精炼法 meaning in English

purifying method
refining process

Abstract : the oxidation refining method is an effective process to refine the 75 % si - fe alloy . the thermal balance of the process is calculated , which provides the theoretical basis for the possibility of the normal casting of the alloy after being refined
