What is a Four stage continuous heating furnace? Introduction to the advantages and characteristics of the forging furnace

Four stage continuous heating furnaceIt is an efficient, energy-saving and environment-friendly metal heating device.，is a popular Four stage continuous heating furnace。The following is to introduce the Four stage continuous heating furnace:

1、Brief introduction of Four stage continuous heating furnace

Four stage continuous heating furnaceIt is a kind of equipment which uses gas as fuel and is specially used for heating metal before forging.。

2、Four stage continuous heating furnace structure composition

The Four stage continuous heating 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. 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. furnace chamber

A space for holding metallic materials for heating.

5. Radiation chamber

The heat load of the main place for Four stage continuous 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、Four stage continuous heating furnace function

Four stage continuous heating furnaceit has the functions of quench, anneal, normalizing, Casting heating and Forging heating，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 metal material can be heated to the required temperature in a short time, and the production efficiency is improved.、It has the advantages of high heating efficiency, high energy utilization, accurate temperature control, good environmental protection performance, simple operation and strong adaptability.、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.、Efficient combustion and waste heat recovery system can significantly reduce energy consumption, thus reducing operating costs.，it is mainly composed of ventilation system, combustor, Radiation chamber, convection chamber and furnace chamber，This productThe overall structural design is simple and novel.。

The Four stage continuous heating furnace structure is introduced as follows:

1. combustor

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

2. ventilation system

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

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. 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.

Four stage continuous heating furnace

Four stage continuous heating furnaceIt is a forging heating device using gas as fuel.，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.，usually used in war industry, electron, Machinery manufacturing, chemical industry, building materials and other fields。
