What is a Pit type roasting furnace? Introduction to the advantages and characteristics of heating furnace functions

Pit type roasting furnaceIt is an efficient, energy-saving and environment-friendly metal heating device.。The following is to introduce the Pit type roasting furnace:

1、Brief introduction of Pit type roasting furnace

Pit type roasting furnaceIt 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.，Uniform heating and precise control can be realized, so it is helpful to improve the product quality and yield of metal materials.、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.、It can improve the plasticity and fluidity of metal materials, reduce the difficulty and cost of forging, and improve product quality and production efficiency.、Adopting advanced combustion technology and materials, it has a long service life and low maintenance cost.、It has the advantages of high heating efficiency, high energy utilization, accurate temperature control, good environmental protection performance, simple operation and strong adaptability.。

2、Pit type roasting furnace structure

The Pit type roasting furnace structure is introduced as follows:

1. furnace chamber

A space for holding metallic materials for heating.

2. combustor

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

3. convection chamber

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

4. ventilation system

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

5. Radiation chamber

The heat load of the main place for Pit type roasting 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、Pit type roasting furnace function

Pit type roasting furnaceit has the functions of heat treatment, hardening and tempering, anneal, Forging heating and heat treatment，the principle is simple.The high-temperature flame and flue gas generated by burning gas (such as natural gas and liquefied petroleum gas) in the furnace are used as heat sources to heat metal materials.。

4、Structural characteristics of Pit type roasting furnace

The Pit type roasting 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. 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. ventilation system

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

5、How much is the Pit type roasting furnace?

The Pit type roasting furnace price is introduced as follows:

1. Brand strength

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

2. Different regions

The price of Pit type roasting furnace in Shandong(Province) is much lower than that in other regions, and One-combustion energy saving is a self-produced and self-selling Pit type roasting furnace manufacturer not only pays attention to the quality of products, but also pays more attention to customer satisfaction, and always adopts the marketing strategy of small profits but quick turnover to make the Pit type roasting furnace price positioning more reasonable, low-cost and economical.

3. Brand strength

At present, there are various brands of Pit type roasting furnace in Jinan, Shandong province. The performance, quality and after-sales of products under different brands are different, and the prices of Pit type roasting furnace are different.

4. Proper management mode

Direct-selling manufacturers are cheaper than second-and third-tier dealers because the former earns the difference without going through middlemen; Online sales are cheaper than offline sales, because you need to invest in store fees, employee fees and other related expenses in the later stage; Close-distance sales are cheaper than long-distance sales because the latter consumes a lot of transportation costs.

5. product quality

The selling price of excellent quality products is also high, so users should also consider the quality and price of products comprehensively when purchasing products, so as to buy products with high cost performance.

6、Company service

Pit type roasting furnace after-sales service is perfect, and a complete after-sales service system is established, which can solve customers' problems anytime and anywhere. In addition, our company promises that all customers who purchase this product can enjoy a full set of pre-sale, in-sale and after-sales services.。

One-combustion energy saving

Pit type roasting furnacemultifunctional, with functions such as Casting heating, hardening and tempering, temper, quench and normalizing，Widely used inEnergy conservation and environmental protection,Metal melting and casting,Metal tempering,Improve production efficiency,Energy conservation and environmental protection and so on，at runtime,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.。
