摘要：

In the paper, the effects of the holding time and temperature on Sr content of the Mg-Sr master alloys produced by the metallothermic reduction of SrO into magnesium melt were investigated. The results preliminarily indicated that effects of the holding time and temperature on the Sr content of the Mg-Sr master alloys produced by the metallothermic reduction of SrO into magnesium melt were relatively obvious. For a given experimental conditions: magnesium melt of similar to 10 kg and powder flow rate to carrier gas flow rate ratio of 20 g SrO/min / 15 L Ar/min, with the increasing of holding time from 30min to 150 min at 800 degrees C or holding temperature from 700 degrees C to 850 degrees C for 90 min, the Sr content of the Mg-Sr master alloy increased gradually. Obviously, the long holding time or high holding temperature was beneficial to produce Mg-Sr master alloys with high Sr content by the metallothermic reduction of SrO into magnesium melt.
