Muffle Furnace, Digital Display Box Type Resistance Furnace, Furnace Chamber Size 300×400×500mm

Digital Display Box Type Muffle Furnace 1000℃

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.

Product Features:

1.The electric furnace shell is made from thin steel plates, bent and welded to form, with a rectangular integral lining inside made of silicon carbide refractory material. The heating element, wound from iron-nickel-chromium-aluminum alloy wire, is coiled into a spiral shape and inserted into 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 of lightweight refractory material. Insulation is provided between the inner lining and the shell using refractory fiber and expanded perlite products.

2.The resistance furnace is equipped with a KSW type temperature controller and nickel-chromium-nickel silicon thermocouple, capable of measuring, indicating, and automatically controlling the furnace chamber temperature.

3.The electric furnace door is hinged and securely attached to the furnace panel. The door rotates smoothly. To close, turn the handle, latch the door hook, and the door will tightly seal against the furnace opening; to open, simply turn the handle, release the hook, and place the door to the left side. The thermocouple for temperature measurement is inserted through a thermocouple hole on the back of the furnace and secured by a mounting bracket.

4.The product is made from cold-rolled steel sheets, with a smooth and shiny surface finished by electrostatic powder coating.

5.Digital temperature controller for precise temperature control, easy operation, and stable temperature regulation.
