✦ Synopsis

In current practice,

there is a steady tendency for the increase of production of sealed lead/acid batteries using lead-calcium alloys. The mastering of these alloys is, however, difficult due to debilitating phenomena taking place, the main of which is the instability of alloy composition in the process of grid casting because of calcium oxidation. Thus, production conditions experience certain problems associated with the continuous control of alloy composition, increase of slag formation, the increased consumption of calcium, productivity decrease, increase of rejection and decrease of grid resistance to corrosion. This work examines both lead and leadcalcium alloys, methods for their deformation strengthening, the choice of alloy optimal composition, and procedures for stabilizing calcium during long process periods. A technological scheme is presented for wasteless manufacture of ~lead-calcium grids of stable composition with control of alloy structure, increased corrosion properties and high productivity.
