A computer determines a thickness and/or a temperature of a metal strip. The computer determines the temperatures occurring along a respective rotation part of the respective surface elements of the rotary elements and a rotary element shape which forms in the region of a draw-off point on the respective surface element, by a respective rotary element model and using an exchanged enthalpy quantity, the respective contact time with a metal and a respective cycle time exchanged per time unit of a respective rotary element of a casting device with the environment thereof. The temperature of the metal situated in the die region, and the heat flow from the metal to the respective surface element, are determined by a respective metallurgical solidification model and using a metal temperature, the temperatures of the surface elements, the rotary element shape and characteristic metal values.

A device for casting electrode carriers for the production of lead grid electrodes in a continuous casting process is provided, which includes a casting drum, the surface of which has been engraved with the shape of the lead strip to be cast, and a casting shoe which rests on the outer circumference of the casting drum in the region of the horizontal axis drawn through the axis of rotation when the casting drum rotates counterclockwise, whereat the exiting liquid lead flows into the concave mold of the casting drum surface and is removable as a solidified lead strip at the lower vertex of the casting drum after three quarters of a rotation and whereat draft angles of less than 7 degrees, in particular less than 3 degrees are provided.

For making battery electrodes, a composite strip of a cast ribbon of an electrically conductive metal attached to and extending along an edge of a web of electrically conductive carbon fiber material, also called a carbon felt in some examples, with a plurality of spaced apart notches cast in the ribbon and opening to an edge of the ribbon spaced from the carbon fiber material. A rotatable drum with a mold cavity and a confronting casting shoe for supplying molten metal, such as liquid lead, to the cavity may be used in a casting machine to continuous cast the composite strip.
