What is a Workpiece heating furnace? Introduction to the principle of Forging furnace structure

Workpiece heating furnaceIt is an efficient, energy-saving and environment-friendly metal heating device.。

1、Brief introduction of Workpiece heating furnace

Workpiece heating furnaceIt is a kind of equipment that uses natural gas as fuel to heat metal materials and make them reach forging temperature.，the principle is simple.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.，the main features are energy saving and environmental protection, Easy to maintain, Stable and reliable, Strong adaptability and energy-efficient，multifunctional, with functions such as hardening and tempering, temper, quench, quench and normalizing，is designed by One-combustion energy saving with advanced technology。

2、Functional advantages of Workpiece heating furnace

Workpiece heating furnaces have the following advantages.

1. Intelligent control

The Workpiece 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.

2. Extend the service life of equipment

The Workpiece heating furnace adopts advanced combustion technology and materials, which has a long service life and low maintenance cost.

3. Efficient combustion

The Workpiece heating furnace adopts advanced combustion technology and control system, which 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.

4. Uniform heating

The Workpiece 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.

5. Rapid temperature rise

3、Advantages of Workpiece heating furnace principle

Workpiece heating furnacein the course of work,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.，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 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.、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.、Natural gas is mainly used as fuel, but some equipment also supports other types of gas or liquid fuel, which has strong fuel adaptability.。

4、Structural advantages of Workpiece heating furnace

The Workpiece heating furnace has the following structure

1. Radiation chamber

The heat load of the main place for Workpiece 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.

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

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