2、Tubular continuous heating furnace application

Tubular continuous heating furnaces have the following purposes.

1. Improve production efficiency

The Tubular continuous 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.

2. Metal melting and casting

Although it is mainly used for forging heating, some types of Tubular continuous 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 heat treatment

In addition to forging heating, Tubular continuous 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.

4. Energy conservation and environmental protection

The Tubular continuous 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 tempering

By properly heating and cooling the metal material, the Tubular continuous 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.

3、Structural advantages of Tubular continuous heating furnace

The Tubular continuous heating furnace has the following structure

1. combustor

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

2. ventilation system

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

3. 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.

4. Waste heat recovery system

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

5. Radiation chamber

The heat load of the main place for Tubular continuous heating furnace heat exchange accounts for about 70%-80% of the whole furnace. The furnace tube in the radiation room conducts heat through flame or high-temperature flue gas, which is mainly radiant heat, so it is called radiation tube.
