Introduction to Annular heating furnace, advantages, characteristics and principles of forging furnace

Annular heating furnaceIt is a kind of equipment that uses natural gas as fuel to heat metal materials and make them reach forging temperature.，has been favored by more and more customers.。

1、Brief introduction of Annular heating furnace

Annular heating 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.。

2、Advantages of Annular heating furnace principle

Annular heating 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.，Cheap and high quality。

3、Structural characteristics of Annular heating furnace

The Annular heating furnace structure is introduced as follows:

1. furnace chamber

A space for holding metallic materials for heating.

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. ventilation system

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

5. Radiation chamber

The heat load of the main place for Annular 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.

5、Annular heating furnace advantage

The advantages of Annular heating furnace are as follows:

1. Extend the service life of equipment

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

2. Intelligent control

The Annular heating 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. Reduce operating costs

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

4. Efficient combustion

The Annular heating 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.

5. Wide application range

The Annular heating 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.
