Introduction to Circular trolley heating furnace and Forging furnace working principle

Circular trolley 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.，energy-efficient,Strong adaptability,energy saving and environmental protection,Easy to control,energy-efficient，widely used in automobile, war industry, petroleum, material, Household necessities and other fields，the principle is simple.Heat of combustion based on fuel. Fuel gas (such as natural gas, liquefied petroleum gas, etc.) is mixed with combustion-supporting air through the burner and burned to produce high-temperature flame and flue gas. These high-temperature flames and smoke exchange heat with metal materials in the furnace, so that they gradually heat up to the temperature required for forging.，features include Easy to maintain, Stable and reliable, Easy to maintain, Stable and reliable and Strong adaptability。The following is to introduce the Circular trolley heating furnace:

2、Structural advantages of Circular trolley heating furnace

The Circular trolley heating furnace has the following structure

1. ventilation system

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

2. furnace chamber

A space for holding metallic materials for heating.

3. 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. convection chamber

The high-temperature flue gas discharged from the radiation chamber is used for convective heat transfer to further heat the metal materials.

5. Waste heat recovery system

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

3、Structural characteristics of Circular trolley heating furnace

The Circular trolley heating furnace structure is introduced as follows:

1. furnace chamber

A space for holding metallic materials for heating.

2. Radiation chamber

The heat load of the main place for Circular trolley 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.

3. combustor

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

4. ventilation system

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

5. 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、Working principle of Circular trolley heating furnace

Circular trolley heating furnaceat 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.，it is widely used in chemical industry, building materials, metallurgy, machinery, surface treatment and other industries，it has the characteristics of Strong adaptability, Easy to maintain, Easy to control, energy-efficient and energy saving and environmental protection，It is a kind of heating equipment using natural gas as fuel, which is mainly used to heat metal materials to the required forging temperature in a short 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.、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.、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.、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.。
