Abstract
A method of making an apparatus for continuously casting a lead alloy strip includes providing a drum having an aluminum outer circumferential casting surface. The outer circumferential casting surface of the drum is abraded with an angular abrading medium to wear away material from the aluminum outer circumferential casting surface of the drum and to create a coarse, irregular, and non-smooth abraded casting surface configured to reduce the rate of heat transfer and slow cooling of the lead alloy strip cast on the abraded casting surface.

Abstract
An apparatus for direct casting of strip from a pool of molten metal includes a tundish having a feed chamber, a return chamber and a diverting chamber. A lip insert is inserted into the tundish and has an open front for cooperation with a casting surface. The apparatus includes a control mechanism configured to control the surface level of the pool of molten metal in the diverting chamber and in the lip insert, and a movement mechanism configured to move the casting surface upwardly through the pool of molten metal for the casting of metal on the casting surface. The casting surface is an aluminum surface of a cylindrical drum and has a coarse irregular surface formed thereon by biasing with crushed, angular silicon carbide or aluminum silicate.

Abstract
A method of continuously casting a lead alloy strip includes continuously supplying molten lead alloy to a tundish having a lip insert and containing a pool of molten lead alloy. The molten lead alloy is continuously supplied to the pool from a bath maintained at a temperature in the range of 575° to 750° F. The surface level of the molten alloy in the lip insert is controlled to produce a strip of desired thickness. The temperature of the lead alloy in the lip insert is controlled in a range of about 640° to 750° F. An abraded casting surface is moved upwardly through the pool for depositing the lead alloy thereon. The abraded casting surface is cooled to a temperature in the range of about 100° to 210° F. to solidify a strip of lead alloy, and the lead alloy strip is stripped from the abraded casting surface.

Abstract
A process and apparatus for continuously mixing and applying paste to battery grids for use in lead-acid battery systems, in which particulate lead oxide, water and sulphuric acid are reacted in an elongated mixer having a mixing to conveying ratio of about 65:35 to 80:20 with controlled reaction temperature for an exit product temperature in the range of above 60° C. to about 80° C. Additives including reinforcing fibers can be added in an amount up to 0.6 wt % of the lead oxide and carbon and graphite powder can be added in an amount up to 6 wt % of the lead oxide.
