2、Flue type heating furnace use

The purpose of Flue type heating furnace is introduced as follows:

1. Metal heat treatment

In addition to forging heating, Flue 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. Metal melting and casting

Although it is mainly used for forging heating, some types of Flue type heating furnaces can also be used in metal melting and casting processes. This is especially suitable for melting and casting of small or special alloys.

3. Metal tempering

By properly heating and cooling the metal material, the Flue 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. Energy conservation and environmental protection

The Flue type heating furnace uses clean energy as fuel, which has lower emissions and higher energy efficiency than traditional coal-fired or oil-fired stoves. This is helpful to reduce environmental pollution and realize green production.

5. Metal melting and casting

Although it is mainly used for forging heating, some types of Flue type heating furnaces can also be used in metal melting and casting processes. This is especially suitable for melting and casting of small or special alloys.

3、Structural characteristics of Flue type heating furnace

The Flue type heating furnace structure is introduced as follows:

1. furnace chamber

A space for holding metallic materials for heating.

2. convection chamber

The material is heated by convection heat transfer of high temperature flue gas discharged from the radiation chamber. Flue gas washes the tube wall of the furnace tube at a high speed to carry out effective convection heat transfer, and its heat load accounts for about 20%-30% of the whole furnace. The convection chamber is generally arranged above the radiation chamber, and some are placed on the ground alone. In order to improve the heat transfer effect, nail head tubes or finned tubes are often used in furnace tubes.

3. convection chamber

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

4. combustor

The device that mixes natural gas with combustion-supporting air and ejects it is the core component of the heating furnace.

5. ventilation system

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

4、Working principle of Flue type heating furnace

Flue type heating furnaceThe 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.，the main features are energy saving and environmental protection, energy-efficient, Easy to maintain, Easy to control and Strong adaptability，Usually equipped with intelligent control system, it can automatically adjust the parameters such as gas supply and air flow according to the heating demand, and realize accurate control of the temperature and atmosphere in the furnace.、The user interface is friendly, and the operator is easy to use. At the same time, the equipment also has the function of fault diagnosis and alarm, which can find and deal with abnormal situations in time.、Adopting advanced combustion technology and control system can realize full combustion of natural gas and improve combustion efficiency. At the same time, some equipment is also equipped with waste heat recovery system, which can further recycle the waste heat in exhaust smoke and improve energy utilization efficiency.、Adopting advanced combustion technology and materials, it has a long service life and low maintenance cost.、The use of clean and environmentally friendly natural gas as fuel effectively avoids the adverse effects of chemical reactions between impurities such as coal-fired furnaces and forgings during heating. At the same time, natural gas has high calorific value and high combustion temperature, and the combustion temperature can be further increased by preheating air and fuel. In addition, the gas forging heating furnace also has good heat loss control ability and intelligent control system, which can accurately adjust the ratio of air to natural gas, ensure full combustion of natural gas, and reduce mechanical incomplete combustion and chemical incomplete combustion.，it has the characteristics of Stable and reliable, energy saving and environmental protection, Stable and reliable, Easy to maintain and Easy to control，is a common Flue type heating furnace。
