摘要

用气泡内最大压力法测定了十二种铸造镁合金熔渣的表面张力

考察了LiCl、MgF

、KF、Al

、MgO、ZrO和ZnO对某些熔渣表面张力的影响。结果表明;十二种熔渣的表面张力值相差不大;合金元素的氧化使表面张力值降低

而LiCl、MgF

、KF使表面张力值增大。

Abstract

The surface tensions of 12 typical casting magnesium alloys slags has been measured

and the influence of LiCl

MgF2

K.F

MgO

A12O3

ZrOz and ZnO oa the surface tensions of some of the slags has been investigated by the maximum bubble method. It is indicated that there is not much difference among the surface tensions of the 12 slags

and the oxides of alloy elements can reduce the surface tensions of the slags

and LiCl

MgF2

K.F can increase
