SXB-2.5-12 Box Type Resistance Furnace, 1200°C Muffle Furnace, Laboratory Electric Furnace, Industrial Electric Furnace

Mafu Furnace Series

Overview of Usage:

Box-type resistance furnace, also known as a muffle furnace, is a periodic operation electric furnace, suitable for use in laboratories of industrial and mining enterprises, scientific research units, etc., for heating during chemical analysis, physical measurements, and general small steel parts heat treatment.

Structural Features:

This series of resistance furnaces is equipped with a KSW-type temperature controller and nickel-chromium-nickel silicon thermocouple, capable of measuring, indicating, and automatically controlling the furnace temperature. The furnace shell is made from thin steel plate, folded and welded into shape. The inner furnace lining is a rectangular integral lining made of silicon carbide refractory material. The heating element, made of iron-nickel-chromium aluminum alloy wire, is wound into a helix shape and passes through the wire grooves on the top, bottom, left, and right of the inner lining. The furnace interior is a sealed structure, with the furnace mouth brick and door brick made from lightweight refractory material. The initial inner furnace is insulated from the shell using refractory fiber and expanded perlite products.

The electric furnace door is securely fastened to the furnace panel with hinges. The door rotates smoothly. When closing, rotate the handle, latch the door hook, and the door will seal tightly against the furnace opening. To open, simply rotate the handle, release the hook, and place the door to the left side. The thermocouple for temperature measurement is inserted through a thermocouple hole in the back of the furnace and is fixed in place by a mounting bracket.
