1. Structural characteristics
Vertical furnace design
The furnace is in the shape of a deep well, and the crucible can be vertically placed inside the furnace. The furnace door is usually located on the top of the furnace and supports lifting or side opening, which is convenient for automated operation (such as using a robotic arm to take and place samples).
Atmosphere control function
Equipped with a vacuum system or gas inlet device, it can achieve inert gas (such as argon, nitrogen) protection or vacuum environment to prevent material oxidation or volatilization at high temperatures.
Diversified heating elements
Select different heating elements according to temperature requirements:
Resistance wire: suitable for scenarios below 1200 ℃, with low cost;
Silicon carbon rod: with a maximum temperature of 1400 ℃ and a fast heating rate;
Silicon molybdenum rod: can withstand high temperatures of 1700 ℃ and is suitable for processing high melting point materials.
Thermal insulation and insulation design
The furnace is made of refractory materials such as alumina polycrystalline fibers, and the double-layer furnace shell is filled with aluminum silicate fiber blankets or diatomaceous earth bricks to reduce heat loss and improve energy efficiency.

2. Performance advantages
High temperature uniformity
The heating elements are distributed around the furnace, combined with an intelligent program temperature control system (such as PID fuzzy control), to ensure a uniform temperature field inside the furnace, with a temperature difference controlled within ± 5 ℃.
Excellent temperature control accuracy
Adopting 30 segment programmable temperature control, supporting rapid heating and constant temperature maintenance, meeting complex process requirements.
Better security protection
Equipped with pressure relief valve, over temperature alarm and automatic power-off function to prevent abnormal pressure or temperature;
The vacuum system and gas inlet device are independently controlled to avoid cross contamination.
Convenience of operation
The upper opening furnace door design combined with multi-stage hinge long arms provides flexible opening and strong sealing; The control panel integrates temperature, time, and atmosphere parameter settings to simplify the operation process.

3. Application scenarios
Metal material processing
Smelting non-ferrous metals such as aluminum, copper, silver, and their alloys;
Casting and forming precision castings at high temperatures;
Metal powder sintering or diffusion treatment (such as semiconductor chip diffusion).
Synthesis of Ceramics and Inorganic Materials
High temperature sintering of ceramic materials;
The melting and crystallization of inorganic non-metallic compounds such as oxides and nitrides.
Research and Small Batch Production
Preparation of laboratory materials in higher education institutions;
Research and development of new products for industrial and mining enterprises.

4. Key points for purchasing
Temperature range matching
Select the rated temperature based on the melting point of the material (such as 800~1200 ℃, 1400 ℃, or 1700 ℃) to avoid overloading of the heating element.
Atmosphere control requirements
If inert gas protection is required, choose a model with gas inlet device;
If a vacuum environment is required, confirm the vacuum limit and pumping rate.
Furnace size and power
Select the effective size of the furnace according to the sample size (such as Ø 180 × 210mm);
The rated power needs to be balanced with the heating speed and insulation requirements.
Brand and after-sales service
Priority should be given to manufacturers that provide customized services, such as door opening methods and temperature control systems;
Confirm the response speed of after-sales support (such as equipment maintenance, technical training).
