1. A device for production of lead grid electrodes for lead acid batteries in a continuous casting process, said device comprising
a casting wheel with an engraved lead grid structure, and
a casting shoe which rests on an outer circumference of the casting wheel and is configured to feed lead towards the casting wheel,
wherein the casting shoe comprises a two-zone configuration,
wherein a first zone of the two-zone configuration is configured to be heated up above a melting point of lead in order to melt lead for filling the engraved grid structure of the casting wheel,
wherein one or more thermally separated second zones of the two-zone configuration, following the first zone in a direction of rotation of the casting wheel, is configured to be kept below the melting point of lead to support solidification of a previously melted lead from a shoe side of the casting wheel, and
wherein the first and second zones are thermally isolated from each other by an insulator plate.
