2、Natural gas roller bottom heating furnace use

The purpose of Natural gas roller bottom heating furnace is introduced as follows:

1. Energy conservation and environmental protection

The Natural gas roller bottom 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 melting and casting

Although it is mainly used for forging heating, some types of Natural gas roller bottom 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.

3. Metal forging heating

The Natural gas roller bottom 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.

4. Metal tempering

By properly heating and cooling the metal material, the Natural gas roller bottom 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.

5. Metal heat treatment

In addition to forging heating, Natural gas roller bottom 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.

4、Natural gas roller bottom heating furnace structure composition

The Natural gas roller bottom heating furnace structure is introduced as follows:

1. furnace chamber

A space for holding metallic materials for heating.

2. Radiation chamber

The heat load of the main place for Natural gas roller bottom 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.

3. combustor

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

4. convection chamber

The high-temperature flue gas discharged from the radiation chamber is used for convective heat transfer to further heat the metal materials.

5. Waste heat recovery system

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

5、Structural characteristics of Natural gas roller bottom heating furnace

The Natural gas roller bottom 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. furnace chamber

A space for holding metallic materials for heating.

3. combustor

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

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.
