Why does the muffle furnace use double-layer sheet metal? what is the benefit?

   Muffle furnace is a commonly used heating equipment in laboratories and heat treatment workshops. Most of the traditional refractory bricks are still in use. The shell is hot and the wiring trouble is a problem encountered by many users.

   Traditional muffle furnaces generally use a single-layer shell, and the iron sheet directly wraps the hot chamber. This is the most conventional method. The advantage is simple structure and low cost. But the shortcomings are also obvious: long-term use of the shell temperature is hot, the user needs to connect the controller circuit and the heating circuit by themselves, and the thermocouple also needs to be wired by the customer. This requires a certain circuit knowledge and practical ability. It is no small challenge for the reader. Because of the simple structure, the wire connectors are all exposed, which poses no small safety hazards.s46Muffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac

  However, the production technology and process 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 simple, easy-to-use, safe and reliable muffle furnace meets the needs of users. All-in-one smart muffle furnaces are made of double-layer sheet metal, hot chamber + furnace lining + insulation layer + inner tank + air insulation layer + shell. There is also forced cooling by a fan between the inner tank and the outer shell, which greatly improves the hot problem of the furnace shell. The upper part of the furnace is the heating zone, and the lower part is the circuit zone. The control circuit has been connected to the heating circuit inside the furnace, and the user can directly plug in and use it. The installation and connection are very simple. The circuits are protected in the shell, and the circuit cannot be seen outside, and the safety has been greatly improved.s46Muffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
