What is a Pit type heat treatment furnace? Introduction to the Working Principle of heating furnace

Pit type heat treatment furnaceIt is a forging heating device using gas as fuel.，it is widely used in aerospace, shipping, Machinery manufacturing, surface treatment, heat treatment and other industries，Simple structure and reliable operation.，it is usually composed of convection chamber, ventilation system, recovery of waste heat, Radiation chamber and combustor，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.，be loved by our customers.。The following is to introduce the Pit type heat treatment furnace:

3、Pit type heat treatment furnace structure

The Pit type heat treatment furnace structure is introduced as follows:

1. furnace chamber

A space for holding metallic materials for heating.

2. 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.

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. 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、Pit type heat treatment furnace advantage

The advantages of Pit type heat treatment furnace are as follows:

1. Uniform heating

The Pit type heat treatment furnace adopts regenerative combustion system or advanced burner design, which can realize uniform distribution of temperature in the furnace, ensure uniform heating of metal materials and improve product quality.

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. Rapid temperature rise

The Pit type heat treatment furnace can heat the metal material to the required temperature in a short time, which improves the production efficiency.

4. Multiple fuel options

Although the Pit type heat treatment furnace mainly uses natural gas as fuel, some equipment also supports other types of gas or liquid fuel, which has strong fuel adaptability.

5. Reduce operating costs

The efficient combustion and waste heat recovery system of the Pit type heat treatment furnace can significantly reduce energy consumption, thus reducing operating costs.

5、Pit type heat treatment furnace use

The purpose of Pit type heat treatment furnace is introduced as follows:

1. Energy conservation and environmental protection

The Pit type heat treatment furnace uses clean energy as fuel, which has lower emissions and higher energy efficiency than traditional coal-fired or oil-fired stoves. This is helpful to reduce environmental pollution and realize green production.

2. Metal heat treatment

In addition to forging heating, Pit type heat treatment furnaces can also be used for metal heat treatment processes, such as annealing and tempering. These processes can improve the microstructure and properties of metal materials, and improve their service life and mechanical properties.

3. Metal melting and casting

Although it is mainly used for forging heating, some types of Pit type heat treatment furnaces can also be used in metal melting and casting processes. This is especially suitable for melting and casting of small or special alloys.

4. Metal tempering

By properly heating and cooling the metal material, the Pit type heat treatment furnace can realize the quenching and tempering treatment of the metal. This is helpful to adjust the hardness and toughness of metal to meet the needs of different workpieces.

5. Metal forging heating

The Pit type heat treatment furnace can heat the metal material to the temperature required for forging, improve its plasticity and fluidity, and thus facilitate forging. This is very important for the forging of various metal materials.
