The box type resistance furnace is generally used in schools, laboratories, laboratories, factories and many other enterprises. It can also be used in the heat treatment of small steel parts such as quenching, annealing and tempering. Of course, the box type resistance furnace can also be used as high heat for metals, ceramics, dissolution and analysis.

Box type furnace products must be operated under high temperature conditions, so what we want to think is that it must pass the high temperature test. Of course, this test can not be withstood by any equipment. Like ordinary equipment, although it can withstand high temperature baking, the advantage of box type resistance furnace is still negligible, even if the result is us We must rely on box resistance furnace to produce some products. One of the topics we want to talk about today is that heat treatment is a very important link in the production and operation of box type electric furnace. Of course, why box type resistance furnace can withstand high temperature can be seen in the following introduction of heat treatment technology structure.

Introduction of heat treatment technology structure:

1. The shell is made of high-quality cold-rolled steel plate, the surface is sprayed with plastic technology, and the furnace door is side open layout with sensitive opening and closing.

2. The medium temperature box type furnace is a closed type furnace. After being made into spiral shape with electric heating alloy wire as heating element, it is surrounded by the four walls of the furnace. The furnace temperature is uniform during heat dissipation and the service life is prolonged.

3. The high temperature tube resistance furnace adopts high temperature combustion tube, with silicon carbide rod as heating element, which is installed inside the furnace jacket.

4. The high temperature box type resistance furnace uses silicon carbide rod as heating element, which is directly installed in the furnace, with high heat utilization rate.

5. The insulation materials of this series of resistance furnaces use lightweight foam insulation brick and aluminum silicate fiber cotton to reduce the heat storage and thermal conductivity, resulting in the reduction of heat storage time, low surface temperature rise, low loss rate of air furnace and greatly reduced power consumption.

6. The controller is divided into pointer type, digital display type and microcomputer multi band control type
