As you can see from the live video.，One-combustion energy saving It is a kind of equipment that uses natural gas as fuel to heat metal materials and make them reach forging temperature.。

3、Pit type heating furnace application

Pit type heating furnaces have the following purposes.

1. Metal heat treatment

In addition to forging heating, Pit type heating furnaces can also be used for metal heat treatment processes, such as annealing and tempering. These processes can improve the microstructure and properties of metal materials, and improve their service life and mechanical properties.

2. Improve production efficiency

The Pit type heating furnace has the advantages of fast heating speed and accurate temperature control, which can improve production efficiency. This is especially important for mass-produced forging workshops.

3. Metal tempering

By properly heating and cooling the metal material, the Pit type heating furnace can realize the quenching and tempering treatment of the metal. This is helpful to adjust the hardness and toughness of metal to meet the needs of different workpieces.

4. Metal forging heating

The Pit type heating furnace can heat the metal material to the temperature required for forging, improve its plasticity and fluidity, and thus facilitate forging. This is very important for the forging of various metal materials.

5. Improve production efficiency

The Pit type heating furnace has the advantages of fast heating speed and accurate temperature control, which can improve production efficiency. This is especially important for mass-produced forging workshops.

4、Pit type heating furnace structure composition

The Pit type heating furnace has the following structure

1. convection chamber

The high-temperature flue gas discharged from the radiation chamber is used for convective heat transfer to further heat the metal materials.

2. furnace chamber

A space for holding metallic materials for heating.

3. ventilation system

Ensure the gas flow in the furnace and maintain the stability of the atmosphere and temperature in the furnace.

4. Waste heat recovery system

Used to recover the exhaust heat of the heating furnace. There are two kinds of recovery methods, one is to recover by preheating combustion air, so that the recovered heat can return to the furnace again; The other is to use another recovery system to recover heat. The former is called air preheating mode, and the latter is usually called waste heat boiler mode.

5. Waste heat recovery system

Recover the waste heat in the exhaust gas of heating furnace to improve the energy utilization efficiency.

5、Pit type heating furnace principle

Pit type heating furnacein the course of work,The high-temperature flame and flue gas generated when the fuel burns in the furnace are used as heat sources to heat the medium flowing in the tube to reach the specified process temperature. Fuel is ejected from the burner and burned, resulting in high-temperature flame and high-temperature flue gas. The high-temperature flame transfers heat to the furnace tube in the radiation chamber through radiation, and then to the medium in the furnace tube. The high-temperature flue gas enters the convection chamber of the heating furnace upward due to the suction force of the chimney or the action of the induced draft fan, and the heat is transferred to the furnace tube in the convection chamber by convection, and then to the medium in the furnace tube.，super quality and competitive price。

6、Introduction of Pit type heating furnace characteristics

Pit type heating furnace has the following characteristics

1. Strong adaptability

The Pit type heating furnace can be used for forging and heating of bar, round steel, square steel, steel plate and other metal materials, and has a wide range of applications.

2. Stable and reliable

The Pit type heating furnace has a stable combustion system and temperature control system, which can ensure the uniformity and stability of the temperature in the furnace, thus improving the quality and production efficiency of forged products.

3. Easy to control

By adjusting the burner and ventilation system, the temperature and atmosphere in the furnace can be accurately controlled to meet the heating requirements of different metal materials.

4. Efficient heating

The Pit type heating furnace can heat the metal to the required forging temperature in a very short time, reducing the loss caused by the oxidation of the metal.

5. energy saving and environmental protection

Natural gas is a kind of clean energy, which produces less waste gas and waste smoke after combustion and has little environmental pollution. At the same time, through wall regenerative combustion technology, flue gas waste heat recovery system and other technical means, the Pit type heating furnace further improves energy utilization efficiency and reduces energy consumption and emissions.
