The digital display box-type electric furnace is a high-performance heating equipment designed for precision and durability. Its outer shell is constructed by folding and welding thin steel plates, ensuring structural strength and stability. Inside, the furnace lining is made of a rectangular integral structure using silicon carbide refractory material, providing excellent thermal insulation and resistance to high temperatures.
Heating elements are strategically placed in the upper, lower, left, and right grooves of the inner lining. These elements are made from iron-nickel-chromium alloy wire, wound into a spiral shape to ensure even heat distribution throughout the chamber. The furnace features a sealed design, with the furnace mouth and door bricks made from lightweight refractory materials, enhancing energy efficiency and reducing heat loss.
To further improve thermal performance, the inner lining and furnace shell are reinforced with refractory fiber and expanded perlite products, offering additional insulation and protection against thermal stress. The exterior is manufactured using cold-rolled steel plates, giving it a smooth, bright surface finish that is both aesthetically pleasing and easy to clean.
This box-type resistance furnace, commonly referred to as a muffle furnace, is widely used in industrial, mining, and research laboratories for a variety of applications. It is ideal for chemical analysis, physical testing, and the heat treatment of small metal parts. Its reliable performance and user-friendly digital control system make it a versatile choice for both routine and specialized processes. Whether you're conducting scientific experiments or industrial production, this furnace offers consistent results and long-term value.
