3、Structural characteristics of Box type heat treatment furnace

The Box type heat treatment 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 Box type heat treatment 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.

4、Box type heat treatment furnace principle

Box type heat treatment furnaceat work,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.，features include Strong adaptability, Easy to maintain, Easy to control, Stable and reliable and energy saving and environmental protection，It is a forging heating device using gas as fuel.，The metal material can be heated to the required temperature in a short time, and the production efficiency is improved.、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.、Efficient combustion and waste heat recovery system can significantly reduce energy consumption, thus reducing operating costs.、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.，usually used in petroleum, heat treatment, light industry, chemical industry, Machinery manufacturing and other fields。

Box type heat treatment furnaceat runtime,The high-temperature flame and flue gas generated when the fuel burns in the furnace are used as heat sources to heat the medium flowing in the tube to reach the specified process temperature. Fuel is ejected from the burner and burned, resulting in high-temperature flame and high-temperature flue gas. The high-temperature flame transfers heat to the furnace tube in the radiation chamber through radiation, and then to the medium in the furnace tube. The high-temperature flue gas enters the convection chamber of the heating furnace upward due to the suction force of the chimney or the action of the induced draft fan, and the heat is transferred to the furnace tube in the convection chamber by convection, and then to the medium in the furnace tube.，It is a kind of equipment that uses natural gas as fuel to heat metal materials and make them reach forging temperature.，Simple structure and advanced technology.，it has the structure of ventilation system, convection chamber, ventilation system, recovery of waste heat and Radiation chamber。
