To provide a method for manufacturing a substrate for a lead storage battery which inhibits the formation of dross in a melting/holding furnace for lead, and to provide a manufacturing apparatus therefor.

The method for manufacturing the substrate 12 for the lead storage battery through the steps of casting molten lead or a lead alloy 5 which have been melted in the melting/holding furnace 1 into a grid substrate 12 by using a substrate-casting machine 2 includes the steps of: continuously melting a substrate-cut scrap 3 produced in the substrate-casting machine 2 while reducing the oxide of the surface; and returning the molten lead or the lead alloy to the melting/holding furnace 1. In an apparatus for manufacturing the substrate 12 for the lead storage battery, which has the melting/holding furnace 1 for lead or the lead alloy and a substrate-casting machine 2 as a main part, the apparatus for manufacturing the substrate 12 further has a continuous reductive melting furnace 4 for reducing and melting the oxide on the surface of a substrate-cut scrap 3 produced in the substrate-casting machine 2 and returning the molten lead or the lead alloy to the melting/holding furnace 1. The formation of the dross can be more adequately prevented by using a molten-lead recovery container or a lead scrap delivery machine.
