2、Introduction of advantages of Large scale tubular quenching furnace

Large scale tubular quenching furnaces have the following advantages.

1. Wide application range

The Large scale tubular quenching furnace is suitable for forging and heating of various metal materials, including steel, aluminum and copper. At the same time, it can also be used in metal heat treatment, tempering and other technological processes.

2. Rapid temperature rise

The Large scale tubular quenching furnace can heat the metal material to the required temperature in a short time, which improves the production efficiency.

3. Efficient combustion

The Large scale tubular quenching furnace adopts advanced combustion technology and control system, which 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.

4. 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.

5. Intelligent control

The Large scale tubular quenching 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.

3、Large scale tubular quenching furnace use

The purpose of Large scale tubular quenching furnace is introduced as follows:

1. Metal forging heating

The Large scale tubular quenching 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.

2. Metal tempering

By properly heating and cooling the metal material, the Large scale tubular quenching 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 heat treatment

In addition to forging heating, Large scale tubular quenching 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 Large scale tubular quenching 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 Large scale tubular quenching 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、Large scale tubular quenching furnace structure composition

The Large scale tubular quenching 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

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. Radiation chamber

The heat load of the main place for Large scale tubular quenching 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.

5、Working principle of Large scale tubular quenching furnace

Large scale tubular quenching furnacein the course of work,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.。
