PROBLEM TO BE SOLVED: To increase the producing quantity of grid bodies for lead accumulator by a continuous casting and to simultaneously produce the grid bodies different in composition. SOLUTION: Two nozzles 2, 3 are provided in one roll 1, the molten metal having the same composition is supplied to each nozzle 2, 3, and the grid bodies 4, 5 are simultaneously taken out to improve the producing speed. Further, the grid bodies 4, 5 different in alloy composition can simultaneously be produced by supplying the molten metals consisting of lead alloys different in composition. |
