1. Efficient processing capability to meet the demands of large-scale production
Large diameter design
Batch processing: Increasing the diameter of the pipe (such as ≥ 150mm) can accommodate more samples or larger sized materials (such as rod-shaped materials, ceramic substrates), increasing the single processing capacity and greatly shortening the production cycle.
Continuous production: With the cooperation of long furnaces (such as 1200mm and above) and automated sampling systems, 24-hour continuous operation can be achieved, suitable for large-scale industrial scenarios such as powder metallurgy and crystal growth.

High heating efficiency
Uniform heating: The large diameter furnace adopts multi zone independent temperature control technology (such as 3-6 zone heating), combined with spiral winding or U-shaped heating elements, to ensure temperature uniformity within the tube ≤ ± 5 ℃, avoiding local overheating or underheating.
Rapid heating: The high power density design increases the heating rate, shortens process time, and improves production efficiency.

2. Wide process adaptability, supporting complex experiments and production
Multi atmosphere control ability
Vacuum environment: equipped with molecular pumps or diffusion pumps, the vacuum degree can reach 10 ⁻² -10 ⁻⁴ Pa, suitable for processes such as metal purification and semiconductor film deposition that require isolation from oxidation.
Gas protection: supports inert gases (N ₂ Ar）、 Introducing reducing gases (H ₂) or reactive gases (CO, NH3) to meet diverse needs such as catalytic reactions and carbonization treatments.
Positive pressure operation: The pressure resistant furnace tube design (such as stainless steel or high-temperature alloy tubes) can withstand a pressure of 0.02 MPa, suitable for special scenarios such as high-pressure synthesis and gas permeation experiments.

Temperature range expansion
Covering the range of low temperature (300 ℃) to ultra-high temperature (≥ 1800 ℃), supporting the entire process from material annealing, sintering to crystal growth, melting, etc.

3. Structural optimization design enhances operational convenience and safety
Modular structure
Quick disassembly and assembly: The furnace tube, heating element, and insulation layer are connected by snap fasteners or flanges, which can quickly complete maintenance or replacement and reduce downtime.
Scalability: Reserved interfaces support subsequent upgrades (such as adding rotation function, vacuum system, or online detection module), extending the service life of the equipment.

Security protection mechanism
Multiple protection: Integrated with over temperature alarm, over-current protection, couple breaking protection, leakage protection, and emergency stop button to ensure safe operation.
Explosion proof design: The furnace tube adopts a sealed flange structure at both ends, combined with a pressure relief valve, to prevent the risk of explosion caused by gas expansion at high temperatures.

4. Energy saving and environmental protection, reducing long-term operating costs
Efficient insulation material
Multi layer composite insulation structure (such as alumina fiber+ceramic fiber+nano aerogel) is adopted, which reduces heat loss and energy consumption compared with traditional furnace type.

Intelligent temperature control system
The PID algorithm combined with fuzzy control technology achieves precise temperature regulation (fluctuation ≤ ± 1 ℃), avoiding energy waste.

5. Data recording and analysis to assist in process optimization
Full traceability function
Built in data acquisition module, real-time recording of temperature, pressure, gas flow rate and other parameters, generating exportable curve graphs or reports, supporting ISO quality system certification requirements.

Remote monitoring and diagnosis
By connecting to a PC or mobile app through IoT technology, remote start stop, parameter adjustment, and fault warning can be achieved, reducing manual inspection costs.

Application scenario examples
New energy materials: Batch preparation of positive electrode materials for lithium-ion batteries (such as NCM, LFP), with a diameter of ≥ 200mm, capable of processing materials weighing over 10kg simultaneously.
Semiconductor industry: Silicon wafer annealing is carried out in a vacuum environment, with the diameter matching the wafer size (such as 300mm) to ensure temperature uniformity of ± 1 ℃.
Powder metallurgy: Continuous sintering of metal powder, combined with rotational function to uniformly heat the powder and improve product density.
Research experiment: Support high-pressure synthesis of new materials (such as diamond and boron nitride), with a pressure of up to 0.02MPa and a temperature of ≥ 1500 ℃.
