Drum for continuous casting machine

摘要

A continuous casting machine for battery grids includes a rotary drum on the outer peripheral surface of which the battery grid pattern is formed by a series of grooves. The peripheral surface of the drum mates with a shoe through which molten lead is directed into the grooves as the drum rotates. The outer periphery of the drum is a shell that is connected to rotary side plates by means of roll pins that enable the shell as a whole to expand and contract independently of the side plates. The drum is maintained at a desired temperature to solidify the molten lead directed into the grooves of the battery grid pattern by circulating a heated liquid through the drum.
