The tube furnace section can reach a working temperature of up to 1500°C. During operation, the steam generator produces steam, which is then introduced into the tube furnace containing materials (such as nutshells) for heating, thereby producing activated carbon. This high-temperature tube furnace is suitable for the dynamic sintering of powders and granules, ensuring more uniform heating of materials, shorter sintering times, reduced energy consumption, and high-quality output. The tube furnace with a steam generator is primarily used in laboratories and enterprises for material sample analysis or large-scale preparation of activated carbon.

The furnace tubes are equipped with flanges featuring pressure gauges and relief valves. When the internal pressure exceeds the preset value, the relief valve automatically opens to release gas, maintaining the desired pressure level.ParameterSpecificationFurnace StructureDual-tube designHeating Zone Length300mm (customizable)Tube Dimensions?60×1200mm (customizable)Operating Temp≤1000oCControl System30-segment PID programmable controllerTemperature Accuracy±1oC (with over-temperature & thermocouple failure alarms)Heating Rate0~10oC/minHeating ElementsHigh-temperature alloy wiresGas SystemVacuum capable; compatible with N, H, etc. (valve-controlled)Temperature SensorType N thermocoupleHousing StructureDouble-walled designSpecial Safety Features of Alloy Tubes:The alloy furnace tubes maintain excellent ductility at 1000oC under normal pressure. If internal pressure exceeds rated limits (beyond the alloy's long-term strength), the tube undergoes creep deformation rather than brittle fracture - gradually developing a controlled crack to safely release gas. This unique failure mode prevents explosive ruptures, instead forming a visible bulge before controlled gas release.Additional Specifications:Sealing Method: Welded flanges at both ends with oxygen-free sealing ringsPressure Gauge: Digital display with programmable high/low pressure alarmsPressure Relief: Spring-adjustable safety valve for automatic pressure regulationCooling System:Cooling fans at both endsDedicated radiators along tube sidesMaintains safe temperatures at flanges/gas connectionsVacuum Monitoring: Digital vacuum gaugeFlow Control: RotameterThe heating elements of the high-temperature tube furnace utilize high-temperature resistance wires, while the furnace chamber insulation is made of polycrystalline fiber material, offering excellent thermal insulation, durability, high tensile strength, no impurity spheres, and high purity, with significantly better energy efficiency compared to domestic fiber materials.The entire furnace body adopts a double-layer inner shell structure with an air gap in between, ensuring that even when the chamber reaches its maximum temperature, the outer surface remains safe to touch without any scalding sensation.This high-temperature tube furnace can perform heat treatment on samples in high-pressure oxygen or inert gas atmospheres, with a maximum temperature of up to 1000°C. Therefore, it serves as a cost-effective experimental tool for research on superconducting materials and dielectric materials.ParameterSpecificationHeating Zone Length440mm (effective size) (customizable)Tube DimensionsOD: 80mm * ID: 70mm * Length: 1000mm (customizable)Operating Temperature≤1000oCTemperature Control30-segment PID programmable automatic controlTemperature Accuracy±1oC (with over-temperature and thermocouple failure alarm)Heating Rate0~10oC/minHeating ElementsResistance wiresCompatible GasesNitrogen, hydrogen and other inert gasesTemperature SensorType N thermocoupleHousing StructureDouble-wall structureTube MaterialSpecial alloy that can withstand 1000oC at normal pressure with good ductility. When internal pressure exceeds the maximum tolerance (beyond the alloy's long-term strength), the tube undergoes creep deformation rather than brittle fracture, gradually developing cracks to release gas. This means even under excessive internal pressure at high temperatures, instead of exploding, the tube will first bulge and then develop cracks to safely vent gas.Flange SpecificationsBoth tube ends are welded with flanges using oxygen-free sealing ringsPressure Relief DeviceAdjustable safety range by replacing springsCooling SystemWhen pressure exceeds set range, the relief valve automatically vents gas to reach preset pressureA 1200°C mini vacuum atmosphere tube furnace is primarily used for high-temperature, medium-temperature, and low-temperature CVD processes in university laboratories and industrial research labs, such as carbon nanotube synthesis, thin-film coating on crystalline silicon substrates, diffusion welding of metal materials, and heat treatment under vacuum or controlled atmospheres.ParameterSpecification / DescriptionFurnace Tube Size?50×600mm (Customizable according to customer requirements)Heating Zone Length200mm (Customizable according to customer requirements)Furnace MaterialHigh-purity alumina fiberMaximum Working Temperature1200°CNormal Working Temperature≤1100°CTemperature ControlPID control, supports 30-segment heating/cooling programsAccuracy: ±1°COver-temperature & thermocouple break protectionHeating Rate0~10°C/minHeating ElementResistance wireVacuum Sealing SystemKF flange sealing at both ends, silicone O-ringTemperature SensorType N thermocoupleFurnace TubeQuartz tubeThis furnace features molybdenum disilicide (MoSi) heating elements and a double-layer shell structure with a 30-segment programmable temperature control system, utilizing phase-shift triggering and thyristor (SCR) control.
