3、Pit type reduction furnace structure

The Pit type reduction furnace structure is introduced as follows:

1. furnace chamber

A space for holding metallic materials for heating.

2. Radiation chamber

The heat load of the main place for Pit type reduction 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 high-temperature flue gas discharged from the radiation chamber is used for convective heat transfer to further heat the metal materials.

4. combustor

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

5. ventilation system

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

Pit type reduction 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.，it can be used in machinery, shipping, automobile, building materials, aerospace and other industries，Using regenerative combustion system or advanced burner design can realize the uniform distribution of temperature in the furnace, ensure the uniform heating of metal materials and improve product quality.、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.、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 has the advantages of high heating efficiency, high energy utilization, accurate temperature control, good environmental protection performance, simple operation and strong adaptability.、The metal material can be heated to the required temperature in a short time, and the production efficiency is improved.。
