Influence of the Structure and Material Parameters on the Temperature Field in a Vacuum Near-Infrared Hot-Pressing Furnace

Abstract:

With its rapid temperature response and high thermal efficiency, near-Infrared (NIR) heating technology is widely used in modern industry, especially in heating furnace. In order to investigate influence of structure and material properties on the heating performance of a vacuum NIR hot-pressing furnace, a series of numerical simulations are utilized. On a variety of factors of power, insulating materials, shielding layers, an optimal proposal is revealed. As a result, the central temperature of the furnace can be up to over 600°C within 20 minutes and the temperature on the outside wall of furnace can be kept to a safe degree for operator, with only one shielding layer of Mo and a silica aerogel layer of 20mm thickness, a kind of excellent heat insulating material.
