Muffle Furnace, Digital Display Box Type Resistance Furnace, Experimental Quenching Furnace, 1000°C

1000Box-type muffle furnace

1200°C Box Type Muffle Furnace

Overview of Application:

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, enabling measurement, indication, and automatic control of the furnace chamber temperature. The furnace shell is made by bending and welding thin steel plates, with the internal furnace lining being a rectangular integral lining made of silicon carbide refractory material. The heating elements, made of iron-nickel-chromium aluminum alloy wire in a helical shape, are wound around the wire grooves at the top, bottom, left, and right of the internal furnace lining. The furnace is sealed in structure, with the furnace mouth bricks and door bricks made of lightweight refractory materials. The initial lining of the furnace is insulated with refractory fibers and expanded perlite products between the inner lining and the furnace shell.

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