The Orton GTF-MD-16 Series (1600°C maximum) Furnace is a specially designed horizontal tube furnaces with controlled, reproducible, linear thermal gradients of approximately 10-12°C per inch. Available in 12" and 16" monitiored zones with 1600°C maximum firing temperature. Thermocouples on 2" centers monitor the temperatures along the gradient zone, so the temperature of the material at any position along the Sample D-tube hearth is known. Visual or post firing analyses of sections taken from the fired material at any position can be measured, recorded, and studied as a function of temperature.
The furnace is a rectangular, metal shell structure that houses the refractory fiber insulation and four molybdenum disilicide heating elements that surround one end of the 2 7/8 ID ceramic heating chamber tube. The samples to be fired are placed on the top of the 2.5 wide high alumina D-tube hearth, which rests on the bottom of the ceramic heating chamber tube. Type "S thermocouples are spaced on 2 centers along the monitored zone and extend vertically through the top of the heating chamber tube. Two IFB end plugs are included to close both ends of the furnace.
Low Temperature Gradient Furnace (1200°C max.)
Furnaces designed with lesser temperature requirements have lower cost. 1200°C max temperature furnaces share the same design features as the higher temperature units but can use lower cost insulation packages, heating elements, power controls and thermocouple sensors.
If your application requires max temperature of 1200°C or less, contact Orton for a special quote to meet your gradient furnace needs.
