2、Working principle of Pre embedded annealing furnace

Pre embedded annealing furnaceHeat 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.，usually used in light industry, Household necessities, automobile, Machinery manufacturing, machinery and other fields。

3、Pre embedded annealing furnace application

The purpose of Pre embedded annealing furnace is introduced as follows:

1. Energy conservation and environmental protection

The Pre embedded annealing 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.

2. Metal forging heating

The Pre embedded annealing 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.

3. Metal tempering

By properly heating and cooling the metal material, the Pre embedded annealing 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 heat treatment

In addition to forging heating, Pre embedded annealing 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.

5. Metal melting and casting

Although it is mainly used for forging heating, some types of Pre embedded annealing 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、Structural characteristics of Pre embedded annealing furnace

The Pre embedded annealing 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. furnace chamber

A space for holding metallic materials for heating.

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. ventilation system

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

5、Pre embedded annealing furnace characteristics

The Pre embedded annealing furnace features are as follows:

1. 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.

2. Efficient heating

The Pre embedded annealing 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.

3. Easy to maintain

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

4. energy saving and environmental protection

Natural gas is a kind of clean energy, which produces less waste gas and waste smoke after combustion and has little environmental pollution. At the same time, through wall regenerative combustion technology, flue gas waste heat recovery system and other technical means, the Pre embedded annealing furnace further improves energy utilization efficiency and reduces energy consumption and emissions.

5. Strong adaptability

The Pre embedded annealing furnace is suitable for forging and heating of various metal materials and has a wide range of applications.
