Introduction to Double pass heating furnace and forging furnace structure principle

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

1、Brief introduction of Double pass heating furnace

Double pass 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.，is based on One-combustion energy saving is a Double pass heating furnace newly developed by One-combustion energy saving。

2、Functional advantages of Double pass heating furnace

Double pass heating furnaces have the following advantages.

1. Rapid temperature rise

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

2. 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.

3. Extend the service life of equipment

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

4. Efficient combustion

The Double pass 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.

5. Wide application range

The Double pass heating furnace is 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.

3、Double pass heating furnace structure

The Double pass heating furnace has the following structure

1. 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.

2. Radiation chamber

The heat load of the main place for Double pass 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. 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.

4. Radiation chamber

The heat load of the main place for Double pass 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. combustor

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

6、How much is the Double pass heating furnace?

The Double pass heating furnace price is introduced as follows:

1. geographical position

There are differences in consumption levels in different regions, which directly affect the production and manufacturing costs of products. Generally speaking, the higher the consumption level, the higher the cost of producing products, and the higher the product cost, the higher the price naturally.

2. After-sales service level

Service factors always affect the sales price of products, and high-quality service will make customers have greater satisfaction and recognition. The service factors mainly include pre-sales service, in-sales service and after-sales service. For each stage of service, our company takes the price factor into account and makes a reasonable judgment between service and price, so that the Double pass heating furnace price and service can meet the actual needs of customers.

3. 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 heating 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 heating furnace is much higher, so customers should choose products directly sold by manufacturers when purchasing.

4. market

Market change is the main factor that affects the price level. Because of the instability and uncertainty of the market, the sales price of Double pass heating furnace will fluctuate greatly, and the market changes are various.

5. Brand strength

At present, there are various brands of Double pass heating furnace in Jinan. The performance, quality and after-sales of products under different brands are different, and the prices of Double pass heating furnace are different.
