Abstract
A lead or lead alloy strip useful for lattice plates of batteries, which is characterized by having recrystallized structure, and a method and apparatus for continuous manufacturing of said alloy strips directly from molten lead or lead alloy advantageously.
Claims7
An apparatus for continuously manufacturing lead or lead alloy strip, comprising:
- (a) means for continuously applying molten lead or lead alloy having a melting point T.sub.0 to a pair of cooling rolls;
- (b) a pair of cooling rolls which simultaneously solidifies said molten lead or lead alloy and shapes the metal into a continuously moving strip having a temperature T.sub.1 which is the temperature of the strip immediately after rolling, said cooling rolls necessarily being cooled in order to continuously cool the molten metal applied to the surface of the pair of rolls;
- (c) means for applying forward tension to said continuously moving strip such that said strip has a forward slip ratio .delta., the forward tension being such that the following relationship is maintained:
- K=.sqroot..delta..times.T.sub.1 /T.sub.0
- wherein 0.45.gtoreq.K.gtoreq.0.17
- (d) take-up means for coiling said continuously moving strip.
