Introduction to Trolley type circulating furnace, introduction to heating furnace function advantages and characteristics

Trolley type circulating 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.。

1、Brief introduction of Trolley type circulating furnace

Trolley type circulating furnaceIt is a kind of equipment that uses natural gas as fuel to heat metal materials and make them reach forging temperature.，it has the characteristics of Easy to control, energy-efficient, Easy to maintain, energy saving and environmental protection and Strong adaptability，it has been widely used in petroleum, automobile, aerospace, Machinery manufacturing, shipping and other industries。

2、Structural advantages of Trolley type circulating furnace

The Trolley type circulating 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. 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. combustor

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

4. furnace chamber

A space for holding metallic materials for heating.

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、Functional advantages of Trolley type circulating furnace

Trolley type circulating furnaces have the following advantages.

1. Rapid temperature rise

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

2. Efficient combustion

The Trolley type circulating 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. Multiple fuel options

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

4. Uniform heating

The Trolley type circulating 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.

5. easy to operate

The operation interface of the Trolley type circulating furnace is friendly and easy for operators to use. At the same time, the equipment also has the function of fault diagnosis and alarm, which can find and deal with abnormal situations in time.

5、Trolley type circulating furnace application

Trolley type circulating furnaces have the following purposes.

1. Energy conservation and environmental protection

The Trolley type circulating 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 melting and casting

Although it is mainly used for forging heating, some types of Trolley type circulating furnaces can also be used in metal melting and casting processes. This is especially suitable for melting and casting of small or special alloys.

3. Metal tempering

By properly heating and cooling the metal material, the Trolley type circulating 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, Trolley type circulating 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 forging heating

The Trolley type circulating 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.
