Three-zone tube furnace
The three-zone tube furnace is equipped with a system that cuts off power when the temperature exceeds the desired range, ensuring safety during operation.
In case of a broken or malfunctioning thermocouple, the quartz tube furnace automatically cuts off power to prevent any potential damage or inaccuracies in temperature measurement.
In the event of a power failure, the furnace is designed to resume operation seamlessly once power is restored. This electric tube furnace ensures continuity and avoids disruptions in the heat treatment process.
The tube furnace is equipped with a robust stainless steel flange support system, which ensures that the tube and flanges remain securely in place.
Three-zone tube furnace feature the famous Kanthal (Sweden) resistance wire as their heating elements. The furnace hearth is built with Mitsubishi (Japan) high-quality fiber materials. The temperature of this furnace is controlled by a high-precision temperature controller (Shimaden fp93 from Japan) with +/-1 °C accuracy and 40 programmable segments. Furnace housing with double-layer steel and two cooling fans inside keep the furnace body temperature low. Stainless steel vacuum sealing flanges seal the furnace tube, it can be used under vacuum and other gas conditions. This tube furnace is an ideal tool for sintering all types of materials/chemicals. Great for labs or college scientific research use. These furnaces have built-in interfaces to a computer. We provide connection cables, adaptors, and software that can be used to control the temperature and parameters of the furnace, all from your PC! You can also save a temperature curve for record or study purposes.
All our tube furnace are CE-certified.
Safety features:
1. Furnace overheat protection cuts off power when the temperature exceeds the desired range.
2. Thermocouple protection cuts off power when the thermocouple is broken or malfunctions.
3. Temperature variation protection cuts off power when the difference between the actual temperature and the target temperature is off the desired range. (refer to controller’s manual)
4. Power failure protection resumes furnace operation right after the point of failure when power is back up.
5. Stainless steel flange support makes sure the tube and flanges are secure and in their absolute position, it also longer the life of the tube.

FAQ
Q1: How does a battery quartz tube furnace work?
A tube furnace works by utilizing heating elements, usually made of materials like silicon molybdenum rods, to generate heat. The furnace consists of a cylindrical chamber or tube where the sample or material to be heated is placed. The heating elements, often located on the outside of the tube, heat the chamber uniformly.
Q2: What is the heating temperature in the battery tube furnace of the thermal cracking process？
In the thermal cracking process, the heating temperature in a tube furnace typically varies depending on the specific requirements of the process. It can range from several hundred degrees Celsius to over a thousand degrees Celsius. The exact temperature is determined by factors such as the desired reaction kinetics, the type of feedstock being cracked, and the desired product yield. The heating temperature is carefully controlled and maintained within the furnace to ensure efficient and controlled cracking of the feedstock.
Q3: How to use a quartz tube furnace?
To use a battery quartz tube furnace:
1. Preparation: Ensure the tube furnace is properly connected to a power source and any necessary gas or vacuum supply.
2. Loading: Open the furnace and carefully place the sample or material to be heated inside the tube or chamber.
3. Setting parameters: Set the desired temperature of the furnace using the temperature control panel or interface. Adjust any additional parameters such as heating rate, holding time, or gas flow rate if applicable.
4. Starting the heating process: Close the furnace and initiate the heating cycle by activating the power supply. The heating elements inside the furnace will gradually increase the temperature to reach the desired level.
5. Monitoring: Continuously monitor the temperature using the built-in temperature control instrument or an external thermometer.
6. Cooling: Once the desired heating process is complete, gradually decrease the temperature or turn off the power supply to initiate the cooling process.
7. Unloading: After the furnace has cooled down to a safe temperature, open it and carefully remove the sample or material.
8. Maintenance: Clean the furnace chamber and ensure it is in proper condition for future use.
Q4: How can furnaces be applied to battery production for the battery quartz tube furnace?
Electrode Materials Preparation: Furnaces are used to heat treat and activate electrode materials such as cathodes and anodes. The materials are coated onto current collectors and then heated in the furnace to optimize their structure and properties for improved battery performance.
Sintering: Battery quartz Tube Furnaces are used for sintering processes, where the active materials in the electrodes are fused together to create a cohesive structure. This enhances the conductivity and stability of the electrodes. etc.
