PIT-Type Heat Treatment Furnace

We live in an era of speed, and this has led to the development of PIT-type furnaces to improve the performance speed of heat treatment operations. These furnaces operate for longer periods, perform reliably, and are very easy to maintain and service. These advantages have made PIT-type furnaces manufactured by Fateh Kavan Arvand among the most popular furnaces in the industry.

Introduction to PIT-Type Furnace

The PIT-type furnace is a cylindrical furnace, also referred to as a vertical retort furnace or shaft furnace. PIT-type furnaces are available in two models: with a sealed tank and without a sealed tank. These furnaces are suitable for both oxidizing atmospheres and neutral atmospheres.

The furnace door has a circular structure with insulation lining. To ensure quick and easy loading and unloading, the doors are designed with a hydraulic rotary mechanism.

Another important feature of PIT-type furnaces is their heating method. These furnaces are heated either electrically or by gas. In electrically heated PIT-type furnaces, resistance strip or wire heating elements are installed along the side walls. The heating elements are properly divided into multiple heating zones and are controlled by PID controllers.

PIT-type furnaces are also equipped with a circulation fan, which moves hot air inside the furnace. The circulation of hot air—whether centrifugal or axial—enhances the efficiency and performance of the furnace. In some cases, two-speed motors can also be used for air circulation.

Another noteworthy feature of these furnaces is their temperature control system, which ensures a high degree of temperature uniformity inside the chamber.

PIT-type furnaces manufactured by Fateh Kavan Arvand are supplied with complete equipment. Optional accessories include a washing machine, overhead crane, quench system, and automatic forklift.

Applications of PIT-Type Furnace

PIT-type furnaces are used for surface hardening or carburizing of various components such as gears, automotive parts, agricultural machinery components, industrial machine parts, and precision rotating components. They are typically used in applications where components need to be exposed to temperatures of up to 1000°C.

These furnaces are widely used in industries involved in the production of forgings, strips, wire, rolls, gears, and bearings. Major industries such as non-metallic alloy manufacturers, aluminum producers, and steel manufacturers are also among the customers of this type of furnace.

PIT-type furnaces are utilized in various processes, including:

• Carburizing
• Gas nitriding
• Normalizing
• Carbonitriding
• Stress relieving
• Aging
• Hardening
• Nitrocarburizing
• Annealing

These furnaces have a significant capacity of up to 10 tons.

PIT-type furnaces are particularly useful in situations where there are limitations in electrical power supply. Under such conditions, they demonstrate high efficiency and can be effectively used for various heat treatment operations.
