2、Gas through furnace use

The purpose of Gas through furnace is introduced as follows:

1. Metal tempering

By properly heating and cooling the metal material, the Gas through 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. Energy conservation and environmental protection

The Gas through 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.

3. Metal forging heating

The Gas through 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 heat treatment

In addition to forging heating, Gas through 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.

5. Metal melting and casting

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

4、Introduction of Gas through furnace characteristics

Gas through furnace has the following characteristics

1. Easy to maintain

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

2. Efficient heating

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

3. Easy to control

The combustion system and ventilation system of the Gas through furnace can be adjusted as required to accurately control the temperature and atmosphere in the furnace and meet the heating requirements of different metal materials.

4. energy saving and environmental protection

As a clean energy source, natural gas produces less pollutants after combustion, which is beneficial to environmental protection. At the same time, the application of waste heat recovery system further improves the energy utilization efficiency.

5. Strong adaptability

The Gas through furnace can be used for forging and heating of bar, round steel, square steel, steel plate and other metal materials, and has a wide range of applications.

5、Structural advantages of Gas through furnace

The Gas through furnace structure is introduced as follows:

1. furnace chamber

A space for holding metallic materials for heating.

2. 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.

3. furnace chamber

A space for holding metallic materials for heating.

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 Gas through 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.

Gas through furnace

Gas through furnaceit has the functions of normalizing, heat treatment, hardening and tempering, Casting heating and quench，Usually equipped with intelligent control system, it can automatically adjust the parameters such as gas supply and air flow according to the heating demand, and realize accurate control of the temperature and atmosphere in the furnace.、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.、Adopting advanced combustion technology and materials, it has a long service life and low maintenance cost.、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.、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.。
