Introduction to tube furnace and heating furnace structure principle

tube furnaceIt is a kind of heating equipment using natural gas as fuel, which is mainly used to heat metal materials to the required forging temperature in a short time.，it has the characteristics of Easy to control, energy saving and environmental protection, energy saving and environmental protection, Stable and reliable and Easy to maintain，has been favored by more and more customers.。

1、Brief introduction of tube furnace

tube furnaceIt is an important heating equipment before metal forging. It uses natural gas as fuel to heat metal materials through high-temperature flame and smoke generated by combustion to meet the requirements of forging process.，it is mainly composed of Radiation chamber, furnace chamber, furnace chamber, Radiation chamber and ventilation system，This tube furnaceThe structure is novel, special, advanced, reasonable and scientific.，the product looks atmospheric.。

2、tube furnace structure composition

The tube furnace structure is introduced as follows:

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. Radiation chamber

The heat load of the main place for 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.

5. 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、tube furnace principle

tube furnacein the course of work,Heat of combustion based on fuel. Fuel gas (such as natural gas, liquefied petroleum gas, etc.) is mixed with combustion-supporting air through the burner and burned to produce high-temperature flame and flue gas. These high-temperature flames and smoke exchange heat with metal materials in the furnace, so that they gradually heat up to the temperature required for forging.。

4、tube furnace characteristics

The tube furnace features are as follows:

1. Efficient heating

The tube furnace can heat the metal to the required forging temperature in a very short time, reducing the loss caused by the oxidation of the metal.

2. Easy to control

By adjusting the burner and ventilation system, the temperature and atmosphere in the furnace can be accurately controlled to meet the heating requirements of different metal materials.

3. Easy to maintain

The structural design of the tube furnace is reasonable and easy to maintain, which reduces the operating cost and failure rate of the equipment.

4. Efficient heating

The tube furnace can heat the metal material to the required temperature in a short time and improve the production efficiency.

5. Easy to control

The combustion system and ventilation system of the tube furnace can be adjusted as required to accurately control the temperature and atmosphere in the furnace and meet the heating requirements of different metal materials.

5、tube furnace performance advantage

The advantages of tube furnace are as follows:

1. Reduce operating costs

The efficient combustion and waste heat recovery system of the tube furnace can significantly reduce energy consumption, thus reducing operating costs.

2. Uniform heating

The tube furnace adopts regenerative combustion system or advanced burner design, which can realize uniform distribution of temperature in the furnace, ensure uniform heating of metal materials and improve product quality.

3. 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.

4. Multiple fuel options

Although the tube furnace mainly uses natural gas as fuel, some equipment also supports other types of gas or liquid fuel, which has strong fuel adaptability.

5. Wide application range

The tube 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.
