PRODUCT PARAMETERS
Description
1400°C Rotary Tube Electric Furnace
The rotary tube furnace is specialized laboratory and industrial equipment designed for continuous high-temperature heat treatment, atmosphere reactions, powder calcination, and material sintering. Featuring a rotary furnace tube structure combined with an independent multi-zone temperature control system and an adjustable tilt angle, the equipment ensures uniform heating and thorough reaction of materials under dynamic rotation, thereby significantly enhancing heat treatment efficiency and consistency. It is particularly well-suited for processes involving the calcination, oxidation, reduction, and atmosphere heat treatment of powder materials.
Product Features
- Openable furnace chamber design for easy maintenance
The furnace features an openable structure, facilitating the replacement of the furnace tube and heating elements, as well as simplifying cleaning and maintenance. Compared to traditional fixed-chamber designs, this significantly reduces maintenance difficulty and time costs.
- Recrystallized silicon carbide furnace tube: high-temperature and thermal shock resistance
The furnace tube is made of recrystallized silicon carbide (SiSiC), with a diameter of 300mm and a heating zone length of 1700mm. Recrystallized silicon carbide has good high-temperature strength, oxidation resistance, and thermal shock resistance.
- Independent control of three temperature zones for superior temperature uniformity
The system features three independently temperature-controlled zones, with heating elements (silicon carbide rods) arranged around the furnace tube to create a uniform heating field. This meets the stringent requirements for temperature consistency in high-temperature material processing.
- Adjustable furnace tube tilt angle for controlled material flow
The furnace tube tilt angle can be adjusted between 1° and 10°, and the rotation speed can be adjusted between 1 and 10 revolutions per minute. By adjusting the tilt angle and rotation speed, the residence time of the material in the tube can be flexibly controlled.
- 304 stainless steel sealing flanges with graphite packing seals
Both ends of the furnace tube are sealed using 304 stainless steel flanges and graphite packing, ensuring excellent high-temperature sealing performance. Flexible stainless steel hoses are used for the material inlet and outlet connections to minimize the impact of equipment vibration.
