Why use a pit-type heat treatment furnace

The reason for using a pit-type heat treatment furnace is mainly based on its unique design advantages and wide applicability, which are specifically reflected in the following aspects:

1. Uniform heating and temperature control:

The pit-type heat treatment furnace adopts a vertical structure, with the workpiece placed inside the pit. This method helps achieve uniform heating and ensures that the workpiece obtains a uniform temperature distribution throughout the heat treatment process. This helps prevent deformation of the workpiece and improve the processing accuracy of the product.

The pit-type furnace is equipped with a reliable temperature control system that can accurately control the internal temperature. This precise temperature control makes the heat treatment process more controllable, ensuring that the metal material achieves the desired mechanical properties and microstructure.

2. Multi-functionality:

The pit-type heat treatment furnace is suitable for a variety of heat treatment processes, including quenching, tempering, normalizing, etc., and can meet the performance requirements of different workpieces.

3. High efficiency and energy saving:

The structural design of the pit-type furnace helps reduce energy consumption. The efficient heating system and insulation layer design make full use of energy during the heat treatment process, achieving energy-saving and high-efficiency results.

The furnace cover and body are made of high-temperature resistant fiber cotton, which has good insulation performance and further saves energy and reduces production costs.

4. Wide applicability:

The pit-type furnace is especially suitable for heat treatment of rod-type and long-axis parts. These workpieces can be placed vertically in the pit-type furnace, reducing the risk of deformation caused by horizontal placement.

The size of large-scale pit-type furnaces can reach a wide range, such as diameters of several meters and depths of more than ten meters, enabling them to handle larger-sized workpieces.

5. Convenient operation and environmental protection:

The workpiece can be conveniently vertically loaded into the furnace for heating using a dedicated crane or traveling crane, reducing labor intensity.

The pit-type furnace is usually equipped with large ventilator devices and multi-zone control to further improve the uniformity of furnace temperature and reduce pollution, which has good environmental benefits.

In summary, the pit-type heat treatment furnace plays an important role in the field of metal processing due to its characteristics of uniform heating, precise temperature control, versatility, high efficiency and energy saving, wide applicability, convenient operation, and environmental protection. Especially in the steel metallurgy, automobile manufacturing, aerospace and other industries, the pit-type heat treatment furnace plays an irreplaceable role.
