PROCESS FOR THE CONTINUOUS MANUFACTURE OF POSITIVE BATTERY GRIDS, AND POSITIVE GRID OBTAINED ACCORDING TO SUCH A METHOD

摘要

The invention concerns a method for the continuous manufacture of acid lead positive battery grids, comprising the following steps: a) preparing a lead alloy containing calcium, at a relative concentration ranging between 0.04 wt.% and 0.12 wt.%, of tin at a relative concentration less than 3 wt.%, aluminium, at a relative concentration ranging between 0.001 wt.% and 0.035 wt.%, and barium, at a relative concentration ranging between 0.02 wt.% and 0.1 wt.%; b) carrying out a continuous casting of said lead alloy; c) mechanically treating said continuous alloy casting to form said positive grids.
