초록 ▼

The strip is cast on a chilled casting surface of a rotating drum from a pool of the molten metal contained in a tundish having a graphite lip insert seated therein cooperating with, the casting surface adjacent to the tundish to form and contain the pool of the molten metal. The tundish preferably contains a feed chamber, a return chamber, and a diverting chamber, the feed chamber and the diverting chamber effectively removing turbulence from the molten feed and the return chamber having a vertically adjustable weir dividing the return chamber from the diverting chamber for controlling the surface level of the pool of molten metal in the diverting chamber and the lip insert and for diverting a flow of molten metal to the return chamber. A preferred lead alloy is a low antimony-lead alloy which is cast into strip and is subjected to a heat treatment to permit expansion and shaping in subsequent production of expanded mesh battery grids. The battery grids produced by the method have improved electrochemical properties such as corrosion resistance and resistance to growth.

A method for the casting of metal strip on a moving, chilled casting surface on substantially the upper half of a rotatable casting drum from a pool of molten metal comprising: providing a tundish containing a pool of molten metal adjacent a substantially vertical portion of said casting surface, said tundish having a feed chamber, a return chamber and a diverting chamber and having an open front in proximity to the casting surface, removably attaching in said tundish adjacent said open front a graphite lip insert having a floor and opposed sidewalls adapted for a fit with the tundish open front whereby said molten metal cannot leak thereby, said graphite lip insert having an open front defined by the lip insert floor and the lip insert sidewalls cooperating with the substantially vertical portion of the casting surface adjacent thereto to contain the pool of said molten metal in the lip insert; controlling the surface level of the pool of molten metal; moving said casting surface upwardly through said pool of the molten metal by rotating said drum for depositing a layer of the molten metal thereon; cooling said molten metal to solidify a strip of the metal on the casting surface; and stripping the metal strip from the casting surface. An apparatus for direct casting of strip from a pool of molten metal in a tundish onto a chilled casting surface adjacent thereto on substantially the upper half of a rotatable casting drum comprising a tundish including a feed chamber, a return chamber and a diverting chamber having passageways communication said chambers in sequence, said tundish having an open front in proximity to a substantially vertical portion of the casting surface, a lip insert having a floor and opposed sidewalls adapted to be inserted into the tundish adjacent the tundish open front, said lip insert having an open front defined by the lip insert floor and sidewalls for cooperation with the casting surface to contain a pool of said molten metal having a surface level within the lip insert, said pool being in pressure communication with the diverting chamber whereby the surface level of the pool in the lip insert is the same as a surface level of molten metal in the diverting chamber, means for controlling the surface level of the pool of said molten metal in the diverting chamber to control the surface level in the lip insert, and means for moving the chilled casting surface upwardly through the pool of molten metal for the casting of metal on the chilled casting surface.
