1400 degrees small heat treatment adjustable temperature high temperature laboratory electric furnace

The precise temperature control system of this 1400°C small-scale, adjustable-temperature laboratory furnace is undoubtedly a valuable aid in scientific research. Its core advantage lies in its advanced PID intelligent algorithm, which monitors temperature fluctuations in the furnace in real time and fine-tunes the power output of the heating elements to maintain temperature deviations within ±1°C. This high-precision temperature control capability is particularly suitable for research on heat-sensitive materials, such as sintering experiments for new ceramic composites or precision alloys.

The furnace structure also reflects user-friendly design considerations. The double-layer stainless steel shell is filled with high-performance insulation material, which not only effectively prevents heat loss but also keeps the shell surface temperature below 60°C, greatly enhancing operational safety. The observation window is made of special quartz glass, which is heat-resistant and highly transparent, allowing researchers to observe sample changes at any time without having to frequently open and close the furnace door, which affects temperature stability.

In practical applications, the modular design of this furnace has demonstrated unique advantages. Users can choose from furnaces with varying capacities (ranging from 1 to 5 liters) to suit their experimental needs, or add an atmosphere control system to enable specialized heat treatments under inert gas protection. A university materials laboratory demonstrated successful thermal annealing of semiconductor wafers using a nitrogen atmosphere. The uniform temperature distribution achieved a resistivity consistency exceeding 98% for the processed wafers.

The 1400°C small, adjustable-temperature laboratory furnace is a common high-temperature device used in laboratories, primarily for heat treatment of materials. The following is a brief introduction:

Furnace Material: High-quality alumina polycrystalline fiber is typically used, such as the 1600-type alumina polycrystalline fiber inorganic material vacuum-formed using Japanese technology. This material has low shrinkage, low thermal conductivity, and excellent thermal insulation properties, effectively reducing heat loss while also withstanding frequent temperature changes without breaking.

Heating Elements: Silicon carbon rods are typically used as heating elements. They feature fast heating, high thermal efficiency, long life, and resistance to deformation at high temperatures. They can operate stably at temperatures up to 1400°C.

Temperature Control System: Utilizing artificial intelligence control technology, this system features PID control and self-tuning functions, and can program multiple temperature ramps, such as 50 ramps. Temperature control accuracy reaches ±1°C, ensuring stable maintenance of the set temperature. Temperature compensation and calibration functions ensure accurate temperature control.

Furnace Structure: These furnaces typically utilize a double-shell structure with air or water cooling between the shells. This effectively reduces heat loss, lowers the furnace surface temperature, and prevents burns. It also helps increase heating speed and save energy.

Safety Features: These furnaces are equipped with an over-temperature alarm and power-off function, as well as leakage protection. Some furnaces also feature a door-opening power-off function to ensure safe experimental operation.

Applications: Primarily used in materials science research, such as sintering, annealing, and quenching processes for ceramics, metals, nanomaterials, and semiconductors. It can also be used in new energy research and development, such as the preparation of lithium battery cathode materials and fuel cell materials. It can also be used in catalyst preparation, performing high-temperature sintering of catalyst supports and active components.

For maintenance, the equipment is equipped with a self-diagnostic function, which displays key parameters such as heating element aging and thermocouple status on the touchscreen. The unique drawer-style furnace design makes replacing heating wires and cleaning the furnace chamber extremely easy, typically requiring only one person to complete the entire maintenance process in less than ten minutes. This design significantly reduces equipment downtime and ensures the continuity of scientific research.
