Abstract (en)
[origin: FR2764905A1] The invention concerns a method for treating molten lead with calcium or its alloys, which consists in introducing the calcium in the bath constantly and continuously in the form of a core welding wire comprising a filler of calcium or calcium alloy inside a sheath meltable or decomposable at a temperature less than 700 DEG C. The additive efficiency of calcium or alloy elements such as magnesium or aluminium is improved.
