2、Functional advantages of Direct heating furnace

Direct heating furnaces have the following advantages.

1. Extend the service life of equipment

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

2. Efficient combustion

The Direct 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.

3. Improve product quality

Because the Direct heating furnace can realize uniform heating and precise control, it is helpful to improve the product quality and yield of metal materials.

4. Rapid temperature rise

The Direct heating furnace can heat the metal material to the required temperature in a short time, which improves the production efficiency.

5. Uniform heating

The Direct heating 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.

Direct heating furnace

As you can see from the live video.，One-combustion energy saving Simple structure and advanced technology.，generally, it is composed of ventilation system, recovery of waste heat, Radiation chamber, convection chamber, ventilation system and other major components。

4、Structural characteristics of Direct heating furnace

The Direct heating furnace has the following structure

1. ventilation system

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

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 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. combustor

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

5、Direct heating furnace application

Direct heating furnaces have the following purposes.

1. Energy conservation and environmental protection

The Direct heating 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 Direct heating 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 Direct heating 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, Direct heating 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 Direct heating furnaces can also be used in metal melting and casting processes. This is especially suitable for melting and casting of small or special alloys.
