Abstract： |
The invention relates to the making of a fluid compression molding of a sacrificial magnesium anode. It heats the magnesium ingot with argon as the protective gas, foaming magnesium alloy coating the smelt alloy solution till the complete smelting temperature of 632deg.C and keeping 30 minutes, preheating the split copple till 250deg.C-280deg.C, pouring the magnesium alloy solutin into the copple and controlled for cooling, getting 20% semi solid blanks when the temperature drops to 618deg.C, preheating the extrusion mold to 250-300deg.C and opening the split copple, dropping the semi solid blank into the extrusion mold, extruding the semi solid blank till the acquisition of AZ31 sacrificial magnesium positive electrode. It expands the making ways of sacrificial magnesium positive electrode with reduced energy consumption and improved quality. |
