What is a Threaded steel heating furnace? Introduction to the advantages, characteristics, and principles of the heating furnace

Threaded steel 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.，it has the characteristics of Strong adaptability, energy saving and environmental protection, Stable and reliable, energy-efficient and Easy to maintain，Widely used in Metal melting and casting, Improve production efficiency, Metal heat treatment, Energy conservation and environmental protection and Metal forging heating，the advantage is 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.、Natural gas is mainly used as fuel, but some equipment also supports other types of gas or liquid fuel, which has strong fuel adaptability.、Uniform heating and precise control can be realized, so it is helpful to improve the product quality and yield of metal materials.、The metal material can be heated to the required temperature in a short time, and the production efficiency is improved.，multifunctional, with functions such as Casting heating, normalizing, heat treatment, temper and anneal。

3、Threaded steel heating furnace structure composition

The Threaded steel 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. combustor

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

3. ventilation system

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

4、Introduction of advantages of Threaded steel heating furnace

The advantages of Threaded steel heating furnace are as follows:

1. clean energy

Natural gas, as a clean energy source, produces less waste gas and dust after combustion, which has little pollution to the environment. This will help reduce industrial emissions and improve the atmospheric environment.

2. Multiple fuel options

Although the Threaded steel heating furnace mainly uses natural gas as fuel, some equipment also supports other types of gas or liquid fuel, which has strong fuel adaptability.

3. Rapid temperature rise

The Threaded steel heating furnace can heat the metal material to the required temperature in a short time, which improves the production efficiency.

4. Intelligent control

The Threaded steel heating furnace is usually equipped with an intelligent control system, which 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.

5. Uniform heating

The Threaded steel heating furnace adopts regenerative combustion system or advanced burner design, which can realize uniform distribution of temperature in the furnace, ensure uniform heating of metal materials and improve product quality.
