Applications

Our Rotary Tube Furnace is equipped with a heating system, an automatic rotation mechanism, (optional)a tilting furnace body. It offers 360° rotation with adjustable speed for a uniform temperature field, and a 15° tilt for easy loading and unloading of materials. The furnace can operate under vacuum or a protective atmosphere. With an open structure cover and gear rotation mechanisms at both ends, it’s particularly well-suited for heat treatment of powder materials. It’s primarily used for unsintered heat treatment of granular powder in various industries, including inorganic non-metal compound materials, lithium-ion electrode materials, ceramic materials, and new energy materials.

standard features

• The furnace tube uses an electrically driven gear structure for a full 360° rotation, with a flexible speed range of 12-20rpm. This ensures the material within the tube is heated uniformly.
• The body of the furnace can be tilted using electric power, with an adjustable tilt angle, facilitating smoother entry and exit of materials.
• It’s fitted with a 304 stainless steel sealing flange, allowing for either a vacuum or atmospheric environment within the furnace tube.
• The high-quality quartz working tube can be replaced with metal or alumina ceramic materials, making it adaptable to various working conditions.
• The stove’s outer casing is made of Q235 low carbon steel, featuring electrostatic and corrosion resistance on the surface. It has a sturdy metal frame shell structure, with a low furnace surface temperature.
• Multi-layer insulation design is crafted from lightweight alumina ceramic fiber and top-grade insulation board backing. It’s asbestos-free, guaranteeing minimal heat loss and low energy consumption.
• The furnace boasts a top-tier heating element, expertly radiating heat within the cavity for unmatched energy efficiency and durability. What’s more, the heating elements are strategically distributed throughout the cavity, promising unparalleled uniformity.
• The temperature control is precise, with minimal temperature fluctuations. It includes temperature compensation and calibration functions, with an accuracy of ±1℃.
• Heating rate: ≤ 25℃/min, a suggested 15℃/min heating rate for a long service life.
• An intelligent microcomputer-based self-tuning PID temperature controller, with SCR/SSR control, can set the heating curve and program 4 groups of 30 segments for program heating, program heat preservation, and program cooling.
• The device features a circuit breaker that trips automatically during a leakage or short circuit, safeguarding both equipment and operators.
• The furnace emits an alarm signal and automatically protects when overheated or when the thermocouple breaks during the working process.
• A variety of tube diameters and heating lengths can be adjusted and customized to accommodate the different physical or chemical requirements of a process.
• Standard configurations: Furnace body -1 set, Thermocouple -1 set, Manual -1 copy, Temperature controller -1 set, High temperature gloves -1 pair, Furnace hook -1 set, Pipe plugs -1 set, Stainless Steel Vacuum Sealing Flange Kit -1 set
• Optional accessories:
  • Optional rotary vane vacuum pump (vacuum degree ≤ 5pa)
  • Optional digital vacuum gauge (1.0×10^5 – 1.0×10^-1pa)
  • Optional float flowmeter (range 60 – 600ml/min)
  • Optional corundum boat
• Quality Certificates: CE, SGS, ISO9001, TUV
