The Joule Heat Pipe Furnace is a type of industrial furnace that uses electrical resistance heating (Joule heating) to generate high temperatures for various thermal processes. In China, these furnaces are widely used in industries such as metallurgy, materials science, ceramics, and chemical processing. The "best sale" Joule Heat Pipe Furnace would depend on factors such as quality, performance, price, and after-sales service.
Here are some key features and considerations for a high-quality Joule Heat Pipe Furnace:
Key Features:
High-Temperature Capability: Can reach temperatures up to 1800°C or higher, depending on the model and heating elements (e.g., silicon carbide, molybdenum disilicide).
Uniform Heating: Designed to provide uniform temperature distribution within the furnace chamber.
Energy Efficiency: Advanced insulation materials and design to minimize heat loss and reduce energy consumption.
Precision Control: Equipped with programmable temperature controllers for precise temperature regulation and process repeatability.
Durable Construction: Made with high-quality refractory materials and heating elements to ensure long service life.
Safety Features: Includes over-temperature protection, alarms, and other safety mechanisms.
Applications:
Heat treatment of metals and alloys
Sintering of ceramics and powder metallurgy
Crystal growth and annealing
Chemical vapor deposition (CVD)
Research and development in material science
(1) Design Temperature: 2200°C. It can be maintained at below 1600°C for at least 30 minutes and at 1600 - 2200°C for at least 300 seconds.
(2) Operating Pressure: -0.08MPa to atmospheric pressure. Non-oxidizing gases can be introduced.
(3) Product Appearance: 600mm in length, 400mm in width, and 600mm in height.
(4) Structure of Graphite Heating Element: Equipped with 3 types of graphite tubes.
- Graphite tube for low-temperature use (700 - 1200°C): Outer diameter is 10mm, inner diameter is 8mm, length is 100mm, and the effective calcination cavity volume is 3.5mL. - Graphite tube for medium-temperature use (700 - 1600°C): Outer diameter is 8mm, inner diameter is 6mm, length is 100mm, and the effective calcination volume is 2mL. - Graphite tube for high-temperature use (700 - 2200°C): Outer diameter is 5mm, inner diameter is 3mm, length is 70mm, and the effective calcination cavity volume is 0.3mL.
(5) Temperature Control Accuracy: ±1°C. (6) Output Voltage and Current of DC Power Supply: Maximum voltage is 12V; maximum current is 250A. ### II. Working Principle and Characteristics A high-power DC power supply is used to convert 220V AC into 12V DC (with high current). The DC power supply supplies electricity to the graphite tube. The material is added into the graphite tube. After the graphite tube is energized with a large current, it heats up rapidly, quickly heating the material inside the graphite tube. An infrared thermometer is used to detect the temperature of the graphite tube and transmit the detection signal to the temperature controller. The temperature controller adjusts the output voltage according to the detected temperature of the graphite tube to maintain the temperature of the graphite tube at the required level. It can rapidly heat up to 2200°C within 25 seconds. It can be maintained at below 1600°C for at least 30 minutes and at 1600 - 2200°C for at least 300 seconds.
