3、Structural advantages of tube furnace

The tube furnace has the following structure

1. ventilation system

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

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. 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.

4. combustor

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

5. 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、tube furnace application

tube furnaces have the following purposes.

1. Improve production efficiency

The tube 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.

2. Metal tempering

By properly heating and cooling the metal material, the tube 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.

3. Metal melting and casting

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

4. Metal tempering

By properly heating and cooling the metal material, the tube 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.

5. Metal heat treatment

In addition to forging heating, tube 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.

5、tube furnace advantage

The advantages of tube furnace are as follows:

1. Intelligent control

The tube furnace is usually equipped with an intelligent control system, which 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.

2. clean energy

Natural gas, as a clean energy source, produces less waste gas and dust after combustion, which has little pollution to the environment. This will help reduce industrial emissions and improve the atmospheric environment.

3. Extend the service life of equipment

The tube furnace adopts advanced combustion technology and materials, which has a long service life and low maintenance cost.

4. Improve product quality

Because the tube furnace can realize uniform heating and precise control, it is helpful to improve the product quality and yield of metal materials.

5. clean energy

Natural gas, as a clean energy source, produces less waste gas and dust after combustion, which has little pollution to the environment. This will help reduce industrial emissions and improve the atmospheric environment.
