What is a Double pass annealing furnace? Introduction to the Working Principle of Forging furnace

Double pass annealing 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.，the product looks atmospheric.，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.、Natural gas is mainly used as fuel, but some equipment also supports other types of gas or liquid fuel, which has strong fuel adaptability.、Suitable for forging and heating of various metal materials, including steel, aluminum and copper. At the same time, it can also be used in metal heat treatment, tempering and other technological processes.、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.，is based on One-combustion energy saving is carefully developed by One-combustion energy saving combined with advanced technology。

2、Working principle of Double pass annealing furnace

Double pass annealing furnaceat work,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 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.、Efficient combustion and waste heat recovery system can significantly reduce energy consumption, thus reducing operating costs.、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.、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.。

5、Structural characteristics of Double pass annealing furnace

The Double pass annealing furnace has the following structure

1. Radiation chamber

The heat load of the main place for Double pass annealing 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. ventilation system

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

3. combustor

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

4. 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.

5. convection chamber

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

6、How much is the Double pass annealing furnace?

The Double pass annealing furnace price is introduced as follows:

1. market competition

The amount of customers' demand for Double pass annealing furnace in the market also has a great influence on the price. When there are many customers purchasing this product in the market and the supply quantity of manufacturers is small, the Double pass annealing furnace price will be very high. On the contrary, when fewer customers purchase this product, there will be a phenomenon of oversupply, and the price of Double pass annealing furnace will naturally be reduced.

2. Manufacturer's strength

Direct selling by manufacturers and sales by middlemen will also affect product prices. There are not too many links among direct selling products, so the cost required by manufacturers is low, and the price of Double pass annealing furnace is low. Customers can also put products into production in advance. On the contrary, when purchasing products from middlemen, there are not only many links, but also the price of Double pass annealing furnace is much higher, so customers should choose products directly sold by manufacturers when purchasing.
