Abstract
A method and machine for continuous casting of a strip of a plurality of serially connected battery grids. The machine may have a rotatable annular mold ring with a cavity at least in part having a plurality of grid molds, and a movable belt overlying at least the axial extent and a portion of the circumferential extent of the mold cavity in at least the area where liquid lead may be supplied to the mold cavity. To supply liquid lead to the mold cavity the mold ring may have a runner system communicating with the mold grids and opening to an end of the mold ring.
Claims25
A machine for continuous casting a strip of a plurality of connected battery grids comprising:
- an annular mold ring rotatable about an axis and with a concentric cylindrical outer surface, axially spaced apart ends, a mold cavity defining at least in part a plurality of grid molds each opening to the outer surface, a runner system communicating with each grid mold adjacent an edge thereof and opening adjacent to one end of the annular ring;
- and
- a movable circumferentially continuous belt with a face overlying at least the axial extent and a portion of the circumferential extent of the mold cavity of the mold ring at least in an area where liquid lead is supplied to the grid molds.
A method of casting a continuous strip of a plurality of connected battery grids comprising:
- rotating a mold ring about a generally vertically disposed axis with a concentric cylindrical outer surface, axially spaced apart ends, a mold cavity defining at least in part a plurality of connected grid molds each opening to the outer surface, a runner system communicating with each mold cavity and opening adjacent to one end of the mold ring,
- moving a continuous belt with a face in part overlying at least the axial extent and a portion of the circumferential extent of the mold cavity in the area in which liquid metal is supplied to the mold cavity;
- and
- supplying liquid metal through the runner system into the mold cavity.
