Wide Range of Applications
KINTEK muffle furnaces, with their capability to reach temperatures up to 1800°C, are versatile tools widely used across various industries and research laboratories for numerous high-temperature applications:
- Sintering: High-temperature bonding of materials, often used in ceramics, metallurgy, and powder metallurgy.
- Annealing: Controlled cooling of materials to relieve stress and improve properties, such as in metalworking and glass production.
- Heat Treatment: Altering the physical and mechanical properties of materials through controlled heating and cooling cycles, including hardening, tempering, and normalizing.
- Ash Melting Point Analysis: Determining the temperature at which ash melts, used in power plants and waste incineration facilities.
- Brazing: Joining metal components using a filler metal with a lower melting point.
- Drug Inspections: Testing the stability and purity of pharmaceutical products.
- Medical Sample Pretreatment: Preparing medical samples for analysis.
- Materials Research: Investigating the properties of materials at high temperatures.
- Nuclear Fuel Disposal: Treating and disposing of nuclear fuel.
- Quality Control: Ensuring the quality of products by testing their thermal properties.
- Water Quality Analysis: Determining the presence and concentration of certain substances in water samples.
Comprehensive Safety Systems
Operator safety is paramount in the design of KINTEK muffle furnaces. Multiple safety features are incorporated to protect users and equipment:
- Over-Temperature Protection: Automatic power cutoff if the furnace exceeds set temperature limits, preventing damage and ensuring safety. Includes over-current protection.
- Door Safety Interlock: Automatically cuts power to the heating elements when the furnace door is opened during operation, protecting the user from high temperatures and ensuring safe sample handling.
- Thermocouple Failure Detection: The furnace will stop heating and an alarm will sound if the thermocouple (temperature sensor) breaks or fails, preventing uncontrolled heating.
- Power Failure Restart Function (KT-18M Pro): In the event of a power outage, the furnace can be programmed to resume the heating program automatically once power is restored, ensuring continuity for long processes.
Operating Principle
KINTEK Muffle Furnaces operate on the principle of resistance heating. An electric current passes through high-resistance heating elements (typically silicon carbide or molybdenum disilicide), causing them to heat up. This heat is then transferred to the furnace chamber by radiation and convection. The chamber, made of high-temperature resistant refractory materials like alumina fiber, is well-insulated to minimize heat loss. A thermocouple placed inside the chamber measures the temperature, which is precisely regulated by a PID controller to maintain the desired temperature setpoint.
