Bell-Type Heat Treatment Furnace

BELL-Type Annealing Furnace (Bell Furnace)

One of the furnaces widely used today due to its numerous advantages is the bell-type annealing furnace, also known as the bell furnace. Its low energy consumption and ability to produce high‑quality products are only some of the benefits it offers. The bell furnace is one of the furnace types supplied by Fateh Kavan Arvand Company.

Introduction to Bell Furnaces

The first aspect to understand when introducing a bell-type annealing furnace is its heating system. The heating system in these furnaces can be either electric or gas-fired. These furnaces also have a movable dome and are used in the annealing industries of both ferrous and non‑ferrous metals such as copper and aluminum alloys, silicon steel, coils, carbon steel, alloy steel, and wires. They are also used for heat treatment operations and bright annealing. The bell-type annealing furnace can heat materials within a temperature range of 650 to 1100 degrees Celsius. This temperature increase is fully controlled and precisely timed.

The structure of bell furnaces consists of three main parts: an inner cover, an outer cover, and a heat source. The components that need to be heated are placed inside the inner cover, while the heat generated by the source is applied around the insulated outer cover of the furnace. This structure ensures that oxidation inside the bell-type annealing furnace is minimized.

Types of Bell Furnaces (BELL Type) and Their Advantages

First, it is useful to know that bell furnaces are categorized into two groups based on the type of loading: square bell furnaces and round bell furnaces.

The use of these furnaces offers many advantages, including improved final product quality, effective sealing, high thermal efficiency, reduced heat loss, high safety during the heating process, increased production efficiency, low energy consumption, and automated operation.

Another advantage that is almost unique to these furnaces is that the bell-type annealing furnace does not require mechanical transfer mechanisms, lifting systems, or a conventional furnace door. This feature results in significant cost savings. This type of furnace is widely used for heat treatment of workpieces.

Conclusion

We discussed the structure, advantages, and types of bell-type annealing furnaces, also known as bell furnaces. The development of this furnace has resolved many of the challenges previously associated with increasing temperature and producing high-quality products. Today, industries that require this type of furnace can consult reputable companies such as Fateh Kavan Arvand Company and order or purchase the furnace through them.
