1200 Degree Rotary Tube Furnace


tob technology

Machine description: The tube of this rotary tube furnace can rotate 360 degrees, one end of the furnace body is equipped with a hinge, and the other end is equipped with a lifting support rod, which can be tilted at a large angle for easy discharge. This furnace uses high-quality alloy resistance wire as heating element, adopts double-layer shell structure and multi-stage program temperature control system, phase-shift triggering, thyristor control, tube furnace hearth adopts alumina polycrystalline fiber material,

The double-layer furnace shell of the tube furnace is equipped with an air-cooling system, which can quickly raise and lower the temperature. The furnace tube is made of high-purity corundum tube, sealed at both ends with stainless steel flanges, and the air flow is controlled by a float flow meter. The furnace has the advantages of balanced temperature field, low surface temperature, fast temperature rise and fall, energy saving, etc. It is an ideal product for high-temperature atmosphere sintering, atmospheric reduction, CVD experiments, and vacuum annealing.

Technical Specifications:

This series of rotary furnace is a new type of high-performance, high-energy-saving electric furnace. It adopts international advanced technology and is developed by our company. It can reduce the surface temperature to normal temperature and make the temperature distribution inside the cavity uniform. Adopt multi-stage intelligent program controller to control the temperature automatically throughout the process. The comprehensive performance index is high and it is in the leading domestic level.

Control features The modular structure of the control system, the long life design of key components of the equipment, simple and reliable technology, good stability and high accuracy.
Air cooling system The Fuji fan impeller is installed directly at the bottom of the double-layer furnace shell and is assembled with the control system.

When the sintering furnace is heated, it is air-cooled, and the air-cooled motor is started. The airflow blows from the fan at high speed to the furnace bladder.

The interlayer of the furnace shell can be used to further cool the circulating convection gas to accelerate the cooling rate of the furnace body.

The low surface temperature of the furnace shell protects the safety of the operator’s operability and improves the effectiveness.

Heating element Using high-quality alloy resistance wire,(The surface is coated with zirconia, which can prolong the service life of the instrument to the greatest extent, and the surface temperature is within 50 ℃.)
Heating element installation position and method Installed in the lower and upper part of the furnace
Refractory The furnace lining is made of ceramic fiber board, and the insulation material is made of vacuum formed fiber poly light board material.

High use temperature, low heat storage, rapid heat and cold resistance, no cracks, no slag drop, good heat preservation performance (energy-saving effect is more than 80% of the old electric furnace). Patented dual-chamber structure, which has the advantages of fast heating, strong and durable, and does not collapse after long-term use

Insulation Materials High-quality alumina multi-fiber insulation material, the insulation layer is 90mm. (Model: LY1400)
Shell The furnace shell is welded by steel plates and profiles, and the shell is equipped with a removable protective plate. The protective plate is electrostatic sprayed and painted. Fine workmanship, beautiful appearance.
Structural features The furnace body heats up and down, heating elements, thermocouples, and controllers. In order to prevent heat loss in the form of heat radiation, a stepped opening and closing seal is used.
Energy saving performance Light weight, fast heating, energy saving over 50%, saving time and effort.
Spare parts A stove hook, a pair of high temperature gloves,
