2、Structural characteristics of Dual regenerative walking furnace

The Dual regenerative walking furnace has the following structure

1. 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.

2. furnace chamber

A space for holding metallic materials for heating.

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. combustor

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

5. Radiation chamber

The heat load of the main place for Dual regenerative walking 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、Dual regenerative walking furnace application

Dual regenerative walking furnaces have the following purposes.

1. Metal melting and casting

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

2. Metal tempering

By properly heating and cooling the metal material, the Dual regenerative walking 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.

3. Metal heat treatment

In addition to forging heating, Dual regenerative walking 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. Metal forging heating

The Dual regenerative walking 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. Improve production efficiency

The Dual regenerative walking 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.

The following is the live video of Dual regenerative walking furnace designed and produced by One-combustion energy saving for users, from which we can see the the advantage is It can improve the plasticity and fluidity of metal materials, reduce the difficulty and cost of forging, and improve product quality and production efficiency.、Adopting advanced combustion technology and control system 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.、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.、Efficient combustion and waste heat recovery system can significantly reduce energy consumption, thus reducing operating costs.、Uniform heating and precise control can be realized, so it is helpful to improve the product quality and yield of metal materials. of Dual regenerative walking furnace.。
