Laboratory Muffle Furnace
This muffle furnace uses 1800-type silicon molybdenum rod as heating element, adopts double-layer shell structure and Yudian 50-stage program temperature control system, and has functions such as phase shift trigger and thyristor control. The furnace is made of 1800-type alumina polycrystalline fiber material, and the double-layer furnace shell is equipped with an air-cooling system, which can quickly raise and lower temperature, and has the functions of over-temperature, break-off, over-current protection and the like. The muffle furnace has the advantages of equal temperature field, low surface temperature, fast temperature rise and fall, and energy saving.
A Muffle furnace allows rapid high-temperature heating, recovery, and cooling in self-contained, energy-efficient cabinets. A muffle furnace separates the object to be heated from all byproducts of combustion from the heat source. In modern electrical furnaces, a radiation or convection energy applies heat to a chamber using a high-temperature heating coil inside insulated material. The insulating material effectively acts as a muffle, preventing heat from escaping
Today’s modern electrical muffle furnaces heat by conduction, convection, or blackbody radiation processes. This process eliminates the creation of combustion byproducts common in non-electric muffle furnaces of the early 20th Century.
Additionally, advances in materials for heating elements such as the molybdenum disilicide can produce working temperatures up to 1,800 degrees Celsius (3,272 degrees Fahrenheit). This high-temperature facilitates more sophisticated metallurgical applications like debinding, sintering, and end to end processes in metal injection molding
