Foundry ladle preheaters are used to heat ladles before they are used in metal casting operations. Preheating helps reduce temperature differences between the ladle and molten metal during handling and pouring. The appropriate preheating equipment depends on the ladle type, foundry process, and operational requirements. Ladle preheaters are part of the wider range of foundry equipment used for molten metal handling, alongside bottom pouring ladles, lip pouring ladles, and ladles with handlers.
