What is a Regenerative through heating furnace? Introduction to the Working Principle of Forging furnace

Regenerative through heating furnaceIt is an important heating equipment before metal forging. It uses natural gas as fuel to heat metal materials through high-temperature flame and smoke generated by combustion to meet the requirements of forging process.。The following is to introduce the Regenerative through heating furnace:

1、Brief introduction of Regenerative through heating furnace

Regenerative through heating furnaceIt is a kind of equipment that uses natural gas as fuel to heat metal materials and make them reach forging temperature.，is a popular Regenerative through heating furnace。

2、Regenerative through heating furnace characteristics

The Regenerative through heating furnace features are as follows:

1. Efficient heating

The Regenerative through heating furnace can heat the metal to the required forging temperature in a very short time, reducing the loss caused by the oxidation of the metal.

2. Strong adaptability

The Regenerative through heating furnace is suitable for forging and heating of various metal materials and has a wide range of applications.

3. energy saving and environmental protection

Natural gas is a kind of clean energy, which produces less waste gas and waste smoke after combustion and has little environmental pollution. At the same time, through wall regenerative combustion technology, flue gas waste heat recovery system and other technical means, the Regenerative through heating furnace further improves energy utilization efficiency and reduces energy consumption and emissions.

4. Efficient heating

The Regenerative through heating furnace can heat the metal material to the required temperature in a short time and improve the production efficiency.

5. Easy to maintain

The structural design of the Regenerative through heating furnace is reasonable and easy to maintain, which reduces the operating cost and failure rate of the equipment.

4、Regenerative through heating furnace structure

The Regenerative through heating furnace structure is introduced as follows:

1. 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.

2. 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. ventilation system

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

4. Radiation chamber

The heat load of the main place for Regenerative through 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.

5. furnace chamber

A space for holding metallic materials for heating.

5、Working principle of Regenerative through heating furnace

Regenerative through heating furnaceat work,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 used as a heat source, resulting in less waste gas and smoke after combustion, and less pollution to the environment. This will help reduce industrial emissions and improve the atmospheric environment.、Suitable for forging and heating of various metal materials, including steel, aluminum and copper. At the same time, it can also be used in metal heat treatment, tempering and other technological processes.、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.、Using regenerative combustion system or advanced burner design can realize the uniform distribution of temperature in the furnace, ensure the uniform heating of metal materials and improve product quality.，multifunctional, with functions such as hardening and tempering, Casting heating, heat treatment, anneal and quench。
