Ladle Dryers, Preheaters, & Dryer-Preheaters

FOR IMMEDIATE RELEASE
Cincinnati, Ohio, United States of America (Free-Press-Release.com) November 15, 2011 -- Metal casting and molding dates back to 3000 B.C. and was originally used to make weapons and cult products. Ever since its inception, the metal casting industry has been continuously changing and growing, with improved equipment and different applications. Today metal casting and molding is used to manufacture weapons, construction structures, art work, automotive parts, and much more. A very important part of this industry is the use of ladles; and consequently, ladle preheaters, dryers and dryer-preheaters.

Ladles, typically found in foundries, are containers which handle the transfer of molten metal. Like other equipment in the metal casting industry, the shape, design, and handling of ladles has evolved over the years. Ladles were originally hand operated. Currently, industries use hydraulics as well as automated rack and pinion assemblies, to transfer and navigate these ladles. The insides of ladles are typically coated with refractory linings to be better equipped for handling the molten metal. Depending on the end product, production rate, and atmospheric conditions, ladles may require a dryer, preheater, or a combination, dryer-preheater.
Ladle preheaters, as the name suggests, are responsible for preheating the ladles to increase the temperature of the container to be comparable to that of the molten metal. This is done to prevent temperature loss from the molten metal, and consequent beading, cracking, oxidation and/or flaking of the end product.

After handling molten metal and contacting air, the lining of ladles will become moist with vaporized steam. In order to ensure the end product is not compromised and that there’s no chance of any water molecules coming into contact with molten metal, the ladle lining must be completely dry between batches. Thus, ladle dryers dry the lining of ladles at a fast and even rate using rapid air circulation at lower temperatures.
Ladle dryer-preheaters are a combination of the two units. They are designed to achieve the high temperatures required for ladle preheating, but include rapid air circulation at lower temperatures required for ladle drying.
