A chamber furnace, named for its box-like structure, is a general-purpose high-temperature heating device widely used in industrial production and laboratory research. It uses electric heating elements to create a uniform high-temperature environment within a confined space, making it suitable for heat treatment, sintering, annealing, ashing, and other processes for a wide range of materials.

II. Basic Structure

1. Furnace Structure
   Outer Shell: Made of high-quality cold-rolled steel or stainless steel, with rust-proof surface treatment

Insulation: Multi-layer composite structure, typically consisting of:

Outer Layer: Aluminum Silicate Fiberboard

Middle Layer: High-purity Alumina Fiber

Inner Layer: Polycrystalline Mullite Fiber

Furnace Door: Double-layer water-cooled structure or pneumatic seal design with observation window

2. Heating System
   Heating Elements:

Resistance Wire (maximum 1200°C)

Silicon Carbide Rod (maximum 1400°C)

Silicon Molybdenum Rod (maximum 1700°C)

Tungsten Wire (maximum 2000°C and above)

Arrangement: Surround heating or top and bottom heating to ensure temperature uniformity

3. Control System
   Temperature Control: PID intelligent regulation with an accuracy of ±1°C

Human-Machine Interface: Touchscreen operation, supports multi-stage temperature programming

Data Logging: Built-in storage, USB export, and remote monitoring

1. Classification by Temperature
