A pit-type heating furnace is a heat treatment equipment that works in a vertical direction. Its name comes from its special pit-like structure. This furnace usually consists of a vertical furnace and a movable top that can rise and fall to load and unload workpieces.

The Main Features of the Pit-type Heating Furnace Include:

1. Vertical design: The furnace body is in the shape of a pit, and the workpiece is placed vertically into the furnace through the opening on the top. This method makes the pit-type heating furnace particularly suitable for processing long or special-shaped workpieces.

2. Heat treatment process: During the heating process, the workpiece is fixed in the furnace and the furnace top is closed to maintain the required temperature and atmosphere. Heating elements are usually arranged around the furnace to ensure that the workpiece is heated evenly.

3. Operation method: The operation of the pit-type heating furnace usually includes placing the workpiece into the furnace, closing the furnace top, setting the heating program, and then starting the heating process. After the heating is completed, the furnace top is opened again to take out the workpiece.

4. Temperature control: The pit heating furnace is usually equipped with a precise temperature control system to ensure a constant temperature throughout the heating process, which is essential to ensure the quality of heat treatment of the workpiece.

5. Energy efficiency: Due to the design of the pit heating furnace, the heat loss of the furnace body is relatively small, so it has high energy efficiency.

The pit heating furnace is suitable for occasions where workpieces need to be loaded vertically, such as heat treatment of springs, steel pipes, long rods, etc. The design of this furnace makes it difficult for the workpiece to deform during the heating process, and it is also convenient to realize the automated production process.

Features of HEATE Instruments-Pit-Type Heating Furnace

1. High-efficiency, energy-saving, environmentally friendly, new high-temperature experimental furnace independently developed and produced;

2. Reasonable structure and beautiful appearance.

3. The shell is made of high-quality cold-rolled steel plate and processed by advanced CNC machine tools.

4. Beautiful two-color imported epoxy powder electrostatic spray painting process, high temperature resistance and corrosion resistance.

5. The double-layer furnace shell is equipped with an air cooling system, which can quickly cool down.

6. All four sides of the furnace are equipped with high-temperature resistant HRE alloy resistance wire electric heating elements; the resistance wire is suspended on the corundum support tube to ensure free heat dissipation and easy replacement if damaged.

7. Thermocouples are inserted from the side of the furnace body to test and control the temperature in the furnace.

8. The furnace cover is opened upwards manually, and the handle is made of high-temperature resistant material to prevent burns when opening.

9. The masonry method of the building block mortise and tenon structure has gradient temperature resistance and less heat storage. The furnace temperature rises and falls quickly, and at the same time, it is strict The furnace working temperature is guaranteed by the standard, and the heat preservation performance is complete.

10. The furnace is heated on all four sides, and the temperature field in the furnace is uniform, which effectively solves the problems of uneven furnace temperature in large furnaces and large differences in sintering of test pieces.
