Box type resistance furnace (popular type)

1、 Product scope of application:

Box type resistance furnace and tube type resistance furnace, also known as Maofu furnace or experimental electric furnace, are both periodic operation electric furnaces. Can be used for chemical analysis by industrial and mining enterprises, scientific research institutions, and laboratories.Physical measurement and general heat treatment of small steel parts. Metal workpieces are used for normalizing, annealing, and quenching in air. .

2、 Structural features:

*The shell of this series of resistance furnaces is made of high-quality steel plates welded by folding, and the inner furnace is a rectangular integral furnace made of high alumina, alumina lightweight or silicon carbide refractory materials.

*1000℃、1200The heating element of the ℃ electric furnace is made of iron chromium aluminum alloy wire wound into a spiral shape and threaded through the wire grooves on the upper, lower, left, and right sides of the inner furnace.

*The furnace is a sealed structure, and the protective bricks and door bricks of the electric furnace are made of lightweight refractory materials. The space between the inner furnace and the furnace shell is filled with high-strength insulation materials.

*Equipped with a digital controller and thermocouple, it can accurately measure, indicate, and automatically control the furnace temperature.

*The electric furnace door is fixed to the electric furnace panel through hinges, and the door rotates flexibly. When closing, rotate the handle to fasten the door hook, and the furnace door can be tightly attached to the furnace mouth. When opening, simply rotate the handle to release it and place the furnace door on the left (right) side

*Type A has the above external characteristics There are also the following characteristics:

*High precision intelligent digital display instrument, temperature control system adopts microcomputer chip processor, with uniform temperature control, precise and reliable.

*Simultaneously display the set temperature and the actual temperature Experiments are more convenient and efficient.
