Different Types of Muffle Furnace

The high-temperature Muffle Furnace is used as heating equipment in the laboratory. Below are mentioned various types of muffle furnaces that are used for different purposes:

  1. Box-type furnace

The box-type high-temperature furnace, as its name implies, is similar to a box, which is a classic muffle furnace, but with more functions and higher thermal insulation performance. The furnace is typically square, with customizable proportions. The front door opens, the door pulls out, and there is a door inside the door for improved heat preservation. This is the most popular high-temperature furnace, and it is ideal for most laboratories.

  1. Well Type Furnace

This form is similar to that of a box-type furnace or an atmosphere furnace. The structure, however, is comparable to that of a crucible furnace. The well-type furnace has a vertical placement, which allows it to take samples and artifacts in a vertical direction. The furnace door opens on the top of the furnace and opens vertically. It is suitable to automate the improvement, such as with an automatic manipulator experiment. Although the furnace of a well-type furnace is typically round, many customers prefer a square furnace.

  1. The Tube Furnace

This kind of furnace is ideal for small samples for heating, sintering that are used in universities and colleges a lot. The artifact is to be set heating region and temperature zone, and the working method is to put quartz or corundum furnace tube into the furnace for heating. The tube furnace has a sealing flange at the end that can create a pre-suction vacuum and be utilized to protect, oxidize, and decrease gas.

  1. Atmosphere Furnace

This high-temperature furnace is known to have both box and tube characteristics. It’s ideal for large-scale sample manufacturing and experimentation, as well as atmospheric requirements. The atmosphere furnace is identical to the high-temperature furnace but with the addition of an air inlet and outlet. The furnace seal welding, which includes a ring of high-temperature-resistant silica gel seal ring on the furnace door, can provide excellent sealing. When you utilize it, you may create a vacuum and a variety of other atmospheres. Although the vacuum effect is slightly worse than that of a tube furnace, it has no bearing on its application.
