Principle

Tube furnaces use a heating element, such as a resistive heating coil or a graphite rod, to heat a process tube. The process tube is typically made of a ceramic material, such as alumina, and is placed inside a furnace chamber. The furnace chamber is then insulated to minimize heat loss. The temperature of the process tube is controlled by a temperature controller, which monitors the temperature of the process tube and adjusts the power to the heating element accordingly. Tube furnaces are used for a variety of applications, including heat treating, annealing, and sintering.

Features

Tube furnaces with alumina tubes are ideal for applications requiring relatively small workspaces and features such as multiple zones, independently controlled. Alumina tubes are required for high-temperature operation, but they are subject to thermal shock. The smaller the diameter of the process tube, the better. KINTEK manufactures tube furnaces for operating temperatures up to 2000 degrees centigrade. In addition to vertical and horizontal tube models, we offer a bottom-loading vertical tube and combination units that allow the tube to be placed either vertically or horizontally. Water-cooled end caps and gas mixing systems are optional.
