2、Multi stage trolley heating furnace application

Multi stage trolley heating furnaces have the following purposes.

1. Metal tempering

By properly heating and cooling the metal material, the Multi stage trolley 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.

2. Metal heat treatment

In addition to forging heating, Multi stage trolley 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.

3. Improve production efficiency

The Multi stage trolley heating furnace has the advantages of fast heating speed and accurate temperature control, which can improve production efficiency. This is especially important for mass-produced forging workshops.

4. Metal melting and casting

Although it is mainly used for forging heating, some types of Multi stage trolley 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.

5. Metal melting and casting

3、Multi stage trolley heating furnace structure composition

The Multi stage trolley heating 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. ventilation system

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

4. 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.

5. Waste heat recovery system

Recover the waste heat in the exhaust gas of heating furnace to improve the energy utilization efficiency.

5、Advantages of Multi stage trolley heating furnace principle

Multi stage trolley heating furnacein the course of work,The high-temperature flame and flue gas generated when the fuel burns in the furnace are used as heat sources to heat the medium flowing in the tube to reach the specified process temperature. Fuel is ejected from the burner and burned, resulting in high-temperature flame and high-temperature flue gas. The high-temperature flame transfers heat to the furnace tube in the radiation chamber through radiation, and then to the medium in the furnace tube. The high-temperature flue gas enters the convection chamber of the heating furnace upward due to the suction force of the chimney or the action of the induced draft fan, and the heat is transferred to the furnace tube in the convection chamber by convection, and then to the medium in the furnace tube.，It can be used for Improve production efficiency, Metal forging heating, Metal heat treatment, Metal tempering, Improve production efficiency, Metal melting and casting and so on。
