What are Tundish & Ladles? Dryers, Preheaters, & Dryer-Preheaters?
The function of ladles and tundishes in the metal industry and the purpose of dryers/ preheaters is discussed below:
Since 3000 B.C. people have been casting and molding metal, originally to make weapons. Today, metal casting and molding is not only used to manufacture weapons, but has grown to include everything from construction structures to automotive parts and art work. Ladle and tundish equipment is very imperative to the casting industry.
Ladles are bowl shaped containers, typically coated with refractory lining, which handle the transfer of molten metal. The ladle pours the molten metal into a tundish, a broad open container with one or more nozzles on the bottom. After the metal cools in the tundish to the perfect casting temperature, it flows through the nozzles into an ingot mold.
Ladle and tundish dryers are used for new refractory linings. Both containers’ linings must be completely dry before production begins in order to ensure that there’s no chance of any water molecules coming into contact with molten metal.
Small variations in the temperature of the molten metal can result in flaws, such as bubbles and cracks, in the final product. In order to prevent temperature loss, ladle and tundish preheaters are used to increase the temperature of the container to be comparable to that of the molten metal.
Dryer-preheaters are a combination unit designed to achieve the high temperatures required for preheating, but include rapid air circulation at lower temperatures required for drying.
