1、Brief introduction of High temperature well tube furnace

High temperature well tube furnaceIt is a kind of equipment which uses gas as fuel and is specially used for heating metal before forging.，The high-temperature flame and flue gas generated when fuel (natural gas) burns in the furnace are used as heat sources to heat the medium flowing in the tube to reach the specified process temperature.，multifunctional, with functions such as heat treatment, Forging heating, Casting heating, anneal and quench，Uniform heating and precise control can be realized, so it is helpful to improve the product quality and yield of metal materials.、Adopting advanced combustion technology and materials, it has a long service life and low maintenance cost.、Natural gas is used as a heat source, resulting in less waste gas and smoke after combustion, and less pollution to the environment. This will help reduce industrial emissions and improve the atmospheric environment.、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.，has been favored by more and more customers.。

2、High temperature well tube furnace application

High temperature well tube furnaces have the following purposes.

1. Metal heat treatment

In addition to forging heating, High temperature well 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.

2. Energy conservation and environmental protection

The High temperature well tube 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.

3. Metal tempering

By properly heating and cooling the metal material, the High temperature well 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.

4. Metal melting and casting

Although it is mainly used for forging heating, some types of High temperature well 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.

5. Improve production efficiency

The High temperature well 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.

3、High temperature well tube furnace structure composition

The High temperature well tube furnace has the following structure

1. Waste heat recovery system

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

2. combustor

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

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. furnace chamber

A space for holding metallic materials for heating.

5. Radiation chamber

The heat load of the main place for High temperature well tube 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.

4、Working principle of High temperature well tube furnace

High temperature well tube furnaceat runtime,Heat of combustion based on fuel. Natural gas is sprayed from the burner, mixed with combustion-supporting air and burned to produce high-temperature flame and smoke. These high-temperature flames and smoke transfer heat to the metal materials in the furnace by radiation and convection, so that they gradually heat up to the temperature required for forging.，is a kind of high quality and low price High temperature well tube furnace，it mainly includes combustor, ventilation system, Radiation chamber, ventilation system and recovery of waste heat，High temperature well tube furnaceThe overall structural design is relatively simple and compact.，features include Easy to maintain, Strong adaptability, Easy to control, energy-efficient and Stable and reliable，the product looks atmospheric.。

5、High temperature well tube furnace structure

The High temperature well tube furnace structure is introduced as follows:

1. ventilation system

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

2. 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.

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. combustor

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

5. furnace chamber

A space for holding metallic materials for heating.
