【発明の名称】金属ストリップの製造方法および装置
Document Type and Number:
Japanese Patent JP3138980
Kind Code:
B2
Abstract:
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.
