Applications
Muffle furnaces are versatile high-temperature heating devices used in various industrial and laboratory settings. They are designed to provide precise temperature control and isolation from combustion contaminants, making them ideal for a range of applications:
- Ashing Samples: Crucial for determining the residue content in organic and inorganic materials.
- Heat Treatment: Essential for processes like annealing, hardening, and tempering of metals and alloys.
- Materials Research: Used to study material behavior at high temperatures and synthesize new materials.
- Melting Glass: Ideal for melting and fusing glass for technical ceramics and enamel coatings.
- Soldering and Brazing: Provides necessary high temperatures for strong and reliable joints.
- Technical Ceramics: Used in the production and testing of technical ceramics requiring precise temperature control.
- Enamel Coatings: Essential for creating durable and aesthetically pleasing enamel coatings.
Comprehensive Safety Systems
- Over-Current and Over-Temperature Protection: The furnace is equipped with over-current protection and over-temperature alarming functions; power will be automatically shut off if thresholds are exceeded.
- Thermal Couple Malfunction Detection: A built-in thermal couple detecting function will stop heating and trigger an alarm if a break or failure is detected.
- Power Failure Restart (KT-14M Pro): The KT-14M Pro model supports a power failure restarting function, allowing the furnace to resume its heating program once power is restored.
Operating Principle
Muffle furnaces operate on the principle of indirect heating. Heating elements located outside a sealed muffle chamber heat the ceramic muffle. This muffle, in turn, radiates heat to the contents inside, ensuring uniform temperature distribution and preventing contamination from the heating elements or combustion byproducts.
