PURPOSE:To attain cost reduction and mass production while improving quality by rapidly raising temperature of a lead alloy molten bath by high frequency induction heating to improve a fusion condition of a plate edge to a strap. CONSTITUTION:Collector edge parts 2 of plates are previously arranged in a receiving part 5 of a lead alloy molten bath 8, to surround the periphery of the receiving part 5 by a coil 7 of a high frequency generator 6, and after pouring the lead alloy molten bath 8, the edge part is heated by flowing a 10 to 50KHz high frequency current in the coil 7, to temporarily generate a high temperature. Hereafter, a mold is cooled by water to solidify a strap. Thus by improving familiarization of the plate collector edge part 2 with the molten bath, a quality of the strap can be improved. A temperature can be mechanically adjusted, to stabilize the quality, and a strap forming time is shortened to improve work efficiency, so that large quantity production and cost reduction can be performed. |
