2、Continuous roller annealing furnace structure composition

The Continuous roller annealing furnace has the following structure

1. furnace chamber

A space for holding metallic materials for heating.

2. Radiation chamber

The heat load of the main place for Continuous roller annealing 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. ventilation system

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

5. Waste heat recovery system

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

4、Continuous roller annealing furnace function

Continuous roller annealing furnaceit has the functions of temper, quench, heat treatment, Casting heating and Forging heating，Mainly used forMetal melting and casting,Metal forging heating,Improve production efficiency,Metal heat treatment andMetal tempering，Simple structure and reliable operation.，it mainly includes ventilation system, convection chamber, recovery of waste heat, combustor and ventilation system，Heat 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.，Natural gas is mainly used as fuel, but some equipment also supports other types of gas or liquid fuel, which has strong fuel adaptability.、The metal material can be heated to the required temperature in a short time, and the production efficiency is improved.、Adopting advanced combustion technology and materials, it has a long service life and low maintenance cost.、The use of clean and environmentally friendly natural gas as fuel effectively avoids the adverse effects of chemical reactions between impurities such as coal-fired furnaces and forgings during heating. At the same time, natural gas has high calorific value and high combustion temperature, and the combustion temperature can be further increased by preheating air and fuel. In addition, the gas forging heating furnace also has good heat loss control ability and intelligent control system, which can accurately adjust the ratio of air to natural gas, ensure full combustion of natural gas, and reduce mechanical incomplete combustion and chemical incomplete combustion.、The user interface is friendly, and the operator is easy 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、Continuous roller annealing furnace application

Continuous roller annealing furnaces have the following purposes.

1. Metal heat treatment

In addition to forging heating, Continuous roller 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.

2. Metal melting and casting

Although it is mainly used for forging heating, some types of Continuous roller 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.

3. Improve production efficiency

The Continuous roller annealing 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 forging heating

The Continuous roller 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.

5. Metal tempering

By properly heating and cooling the metal material, the Continuous roller 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.

Continuous roller annealing furnaceThe structural design is more advanced and reasonable.，structure mainly includes: furnace chamber, convection chamber, ventilation system, furnace chamber, Radiation chamber and so on，at the start of the operation,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 is a forging heating device using gas as fuel.。
