Abstract

A RbCl / BaCl 2 The invention relates to a mixed aerosol and a method for preparing magnesium-based metal semi-solid slurry, belonging to the field of metal material preparation. The RbCl / BaCl 2 Mixed aerosols, including aerosol solutes and aerosol solvents, aerosol solutes account for total RbCl / BaCl 2 The mass percentage of the mixed aerosol is 80-85%; the aerosol solutes are RbCl and BaCl 2 The mixed powder with a mass ratio of 2:3; the aerosol solvent is a single or mixed gas that does not react with the magnesium alloy melt, including but not limited to inert gases and / or protective gases commonly used in magnesium smelting. RbCl / BaCl 2 The mixed aerosol is introduced into the magnesium alloy melt in the semi-solid temperature range and fully contacted to form a magnesium-based metal semi-solid slurry. Compared with the traditional magnesium alloy semi-solid slurry preparation method, the method has the advantages of simple and reliable equipment, stable process and high product quality, and can achieve the effect of energy saving and emission reduction while reducing costs.
