Atmospheric Furnace scaled

Product Features & Applications

Product Feature:

  • High temperature and uniform temperature zone, ensuring consistent heating of testingsample
  • The heating elements utilize high-quality alloy resistance wires or silicon carbide rods and silicon molybdenum rods, paired with an intelligent temperature control system, enabling rapid heating with a temperature accuracy of ±1°C. It supports programmed heating, holding, and cooling
  • The furnace chamber is made of high-purity alumina fiber, offering excellent thermal insulation, low heat storage, resistance to rapid temperature changes, and minimal cracking or deformation
  • Intelligent PID temperature control instrument featuring program functionality, it allows setting temperature ramping curves and supports programming up to 30 segments
  • Equipped with functions such as high-temperature alarm, overcurrent protection, and overload protection, some devices also feature automatic over temperature protection to ensure safe operation and prevent damage or safety incidents caused by abnormal conditions
  • Fastheating rate  (0~10°C/mm), and it takes only about 15 minutes to raise the chamber room temperature to 1000°C
  • Double-layer shell with a forced air cooling system
  • The chamber dimensions can be customized as per requirements
  • Comply with the execution standards: GB 5959, GB/T 10067, IEC 60519, ISO 13577, ASTM A991/A991M

Product Application:

  • Broad application scope, suitable for various scenarios such as material sintering, ceramic firing, metal annealing, ash determination, melting tests, and laboratory high-temperature heat treatment.
