Industrial furnaces are built of several kinds of high temperature materials to hold the process material and hold in the heat without breaking down during the several months that they usually run.

Industrial ovens are typically batch or continuous process insulated enclosures or tunnels used for thermal processing. They are used for a wide range of industrial applications including aging, annealing, baking, burn-off, curing, drying, heat treating, melting, preheating and sterilizing. Industrial ovens are available in a number of common configurations, although custom and specialized models may be designed in conjunction with a supplier.
