Proper Operation of Muffle Furnaces and Precautions for Ash Content Determination

Classification of Muffle Furnaces: Muffle furnaces can be classified according to their heating elements, operating temperatures, and control systems as follows: 1) Based on the heating element: electric resistance wire muffle furnace, silicon carbide rod muffle furnace, and silicon molybdenum rod muffle furnace; 2) Based on the operating temperature: generally divided into box-type muffle furnaces for temperatures below 1000°C, muffle furnaces for 1100°C to 1300°C (silicon carbide rod muffle furnaces), and muffle furnaces for temperatures above 1600°C that use silicon molybdenum rods.

What factors should be considered when selecting a high-temperature box furnace that meets your needs?

Selecting a high-temperature box furnace that meets your specific needs requires considering multiple factors, including temperature requirements, chamber size, heating method, temperature-control accuracy, functional requirements, quality and reliability, and after-sales service. I. Operating Principle The operating principle of a high-temperature box electric furnace is primarily based on the generation of heat through the passage of electric current through resistive elements, followed by heat transfer via air convection, thermal conduction, and the inherent thermal conductivity of the material being heated. Such equipment typically uses resistance wires as the heating element; these wires are heated by the electric current, converting electrical energy into thermal energy and producing high temperatures. The main components of a high-temperature box electric furnace include the outer shell, inner chamber, heating elements, and temperature-control system. The outer shell is usually made of high-temperature-resistant materials.
