CONTINUOUS CASTING OF LEAD ALLOY STRIP FOR HEAVY DUTY BATTERY ELECTRODES

摘要

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.
