1. Working principle
The high-temperature gradient experimental tube furnace converts electrical energy into thermal energy through segmented and independently controlled heating elements, and establishes a non-uniform temperature field in the axial direction of the furnace tube. The core principles include:
Independent temperature control system: Each temperature zone adopts separate temperature sensors and power regulation modules, and precise temperature control is achieved through PID control.
Heating element layout: Heating elements are arranged unevenly according to gradient requirements, and are designed with thermal resistance of insulation materials to form a predetermined temperature distribution.
Heat transfer mode: Radiation heat transfer is the main mode in high-temperature areas, while convective heat transfer is enhanced in low-temperature areas.

2. Technical features
Temperature gradient controllable: capable of forming a stable non-uniform temperature field in the axial direction of the furnace tube according to experimental requirements.
Precise temperature control: adopting PID regulation, fuzzy control, and self-tuning functions, with high temperature control accuracy.
Multiple heating elements to choose from: Depending on the experimental temperature requirements, high thermal stability elements such as silicon carbon rods and silicon molybdenum rods can be selected.
Safety protection function: equipped with over temperature protection, leakage protection and other functions to ensure safe use.
Remote control and data recording: configurable conversion interface to achieve interconnection with computers, complete remote control, real-time tracking, historical recording, output reports and other functions.

3. Application scenarios
Semiconductor material preparation: In the growth, annealing and other processes of semiconductor materials, precise temperature gradient control is required to obtain high-quality materials.
Nanomaterial research: The preparation and performance research of nanomaterials often require specific temperature gradients.
Carbon fiber material processing: The carbonization, graphitization and other processes of carbon fiber materials require a high-temperature gradient environment.
Crystal growth: During the crystal growth process, high-quality single crystal materials can be obtained by controlling the temperature gradient.
Glass crystallization detection: By simulating the crystallization process of glass under different temperature gradients, the crystallization behavior of glass is studied.

4. Purchase suggestions
Clarify experimental requirements: Select appropriate equipment based on parameters such as maximum temperature, temperature gradient range, and furnace tube size required for the experiment.
Pay attention to device performance: Understand key indicators such as temperature control accuracy, heating speed, and insulation performance of the device.
Consider equipment safety: choose equipment with safety functions such as over temperature protection and leakage protection.
Understand after-sales service: Choose a manufacturer that provides comprehensive after-sales service to ensure that the equipment receives timely technical support and maintenance during use.
