METHOD FOR MELTING LEAD SCRAP, AND METHOD FOR MANUFACTURING SUBSTRATE FOR LEAD BATTERY AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a method for melting lead scrap while suppressing the formation of dross and also to provide a method for manufacturing a substrate for a lead battery using the melting method.

SOLUTION: In the method for melting lead scrap, a lead scrap receiving container 2 having a recessed longitudinal section and an opening 2a in the bottom is disposed on a lead or lead alloy melting and holding furnace 1, and lead scrap 4 is fed into the container 2 and heated and melted by a reducing flame, and the resulting melt is allowed to flow gently into molten lead 1d in the melting and holding furnace 1. In the method for manufacturing a substrate for a lead battery where the molten lead or lead alloy 1d melted in the melting and holding furnace 1 is cast into a grating substrate using a substrate casting machine 7, the lead scrap 4 generated in the substrate casting machine 7 is fed into the lead scrap receiving container 2 which has a recessed longitudinal section and an opening 2a in the bottom and disposed on the melting and holding furnace 1, where the lead scrap 4 is heated and melted by a reducing flame and the resulting melt is allowed to flow gently into the molten lead or lead alloy 1d in the melting and holding furnace 1 through the opening 2a of the lead scrap receiving container 2.
