(2) The industrial process of fused salt electrolysis comprises the following: smelting metal in crucible 2 to get metal flux 3; installing electrolysis bath 5 and adding in being electrolyzed salt; installing electrode 8 and electrode 9; using wire 6 to connect to electrolysis power 7; switching the current on to electrolyze; removing leavings; getting metal flux with electrolysis product. The mass of fused salt medium is 0. 2-15 percent of metal flux.

Description

technical field [0001] The invention relates to a device and method for adding elements in metal smelting, belonging to the technical field of metal smelting. Background technique [0002] The methods of adding elements to the metal melt can be roughly divided into adding simple substances, intermediate alloys, and compounds. [0003] When using elemental and intermediate alloys to add elements, the elemental or intermediate alloys can be directly added to the metal melt, and after the elemental or intermediate alloys are melted and corroded, enter the metal melt to realize the addition of elements. This method is also known as the "counter-admixture method". The main advantage of this method is that it is easy to operate and the measurement is more accurate. However, because the microstructure of the pre-prepared elemental or master alloy is generally hereditary, some bad structures will cause the added elements to fail to give the metal good technical properties. Second,...
