2、Introduction of Indirect heating furnace characteristics

Indirect heating furnace has the following characteristics

1. energy saving and environmental protection

As a clean energy source, gas produces less waste gas and waste smoke after combustion, which is beneficial to environmental protection. At the same time, some Indirect heating furnaces are also equipped with waste heat recovery system, which further improves the energy utilization efficiency.

2. Stable and reliable

The Indirect heating furnace has a stable combustion system and temperature control system, which can ensure the uniformity and stability of the temperature in the furnace, thus improving the quality and production efficiency of forged products.

3. Strong adaptability

The Indirect heating furnace can be used for forging and heating of bar, round steel, square steel, steel plate and other metal materials, and has a wide range of applications.

4. Stable and reliable

The Indirect heating furnace has a stable combustion system and temperature control system, which can ensure the uniformity and stability of the temperature in the furnace, thus improving the quality and production efficiency of forged products.

5. Efficient heating

The Indirect heating furnace can heat the metal to the required forging temperature in a very short time, reducing the loss caused by the oxidation of the metal.

4、Indirect heating furnace structure composition

The Indirect heating furnace has the following structure

1. Waste heat recovery system

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

2. Radiation chamber

The heat load of the main place for Indirect 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. ventilation system

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

4. combustor

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

5. 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、Indirect heating furnace principle

Indirect heating furnaceat the start of the operation,The high-temperature flame and flue gas generated when fuel (natural gas) burns in the furnace are used as heat sources to heat the medium flowing in the tube to reach the specified process temperature.，It is an efficient, energy-saving and environment-friendly metal heating device.，is a Indirect heating furnace，was developed and designed by One-combustion energy saving。

6、How much is the Indirect heating furnace?

The Indirect heating furnace price is introduced as follows:

1. product function

The more functions a product has, the higher its manufacturing cost, so that the product can be used by customers as much as possible, which can create more useful value for customers, so the price will be higher.

2. product costs

If the cost of the product is high, the selling price of the product will be high, so the cost input is an important factor that causes the price change of the Indirect heating furnace.

3. Parameter size

There are many specifications and models of Indirect heating furnace, and different specifications and models must have different production processes. Moreover, the capital spent on the production of large-sized products must be much more than that of small-sized products, so the price of large-sized products is relatively high.

4. Company size

The products manufactured by manufacturers of different scales are also different. Large-scale manufacturers have advanced production technology, the quality of products manufactured is reliable, and large-scale manufacturers have perfect after-sales service, which can provide greater protection for customers and the products manufactured are more cost-effective. Therefore, customers should try to choose large manufacturers to purchase.

5. brand

Different brands of products in the same series have more or less differences in product prices, and different brands of Indirect heating furnace have more or less differences in price.

Indirect heating furnace

Indirect heating furnaceCommonly used inMetal tempering,Metal heat treatment,Energy conservation and environmental protection,Metal forging heating,Metal melting and casting and so on，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.、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 materials, it has a long service life and low maintenance cost.、Uniform heating and precise control can be realized, so it is helpful to improve the product quality and yield of metal materials.、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.。
