Why should we use double-layer sheet metal for microwave high temperature muffle furnace?

- Apr 10, 2019-

Microwave high temperature muffle furnace is a heating equipment commonly used in laboratories and heat treatment workshops. Most of the traditional refractory brick muffle furnaces that are still in use today, the outer casing is hot, and the wiring trouble is a problem encountered by many users.


Conventional muffle furnaces generally use a single-layer shell, and the iron sheet directly wraps the hot chamber. This is the most common practice, and the advantages are simple structure and low cost. But the shortcomings are also obvious: when the long-term use, the temperature of the shell is high, the user needs to connect the circuit of the controller and the heating circuit by himself. The thermocouple also needs to be wired by the customer. This requires certain circuit knowledge and hands-on ability. It is no small challenge. Because the structure is simple, the wire connectors are bare, and there is no small safety hazard.


However, the production technology and technology of the muffle furnace are also advancing with the times. We dig deep into the pain points of users, sum up experience and continuously improve. The easy-to-use, safe and reliable muffle furnace is tailored to the needs of the user. The integrated smart muffle furnace is double-layer sheet metal, hot chamber + lining + insulation + inner tank + air insulation + outer casing. There is also a fan forced cooling between the inner casing and the outer casing, which greatly improves the problem of the hot body of the furnace body. The upper part of the furnace is the heating zone and the lower part is the circuit area. The control circuit has been connected to the heating circuit inside the furnace. The user can plug in the power and use it. The installation and connection are very simple. The circuit is protected inside the casing. The circuit is not visible outside, and the safety is greatly improved.
