  • What is a Rotary Tube Furnace?

    By definition, a rotary tube furnace is a heat-treating circular furnace, which rotates during heat-treatment. Samples are transported through the furnace in a circular path as they are heated. Rotary tube furnaces generally burn pulverized, solid, gaseous or liquid fuel into its working section, and then the heating gases created flow towards the sample. These furnaces feature a metal drum lined ...
