What is a Pit type automatic quenching furnace? Introduction to the advantages and characteristics of the forging furnace

Pit type automatic quenching furnaceIt is a forging heating device using gas as fuel.，it is usually composed of furnace chamber, recovery of waste heat, ventilation system, combustor and ventilation system。

1、Brief introduction of Pit type automatic quenching furnace

Pit type automatic quenching 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 has the functions of normalizing, hardening and tempering, Forging heating, anneal and quench，usually used in electron, material, light industry, aerospace, Machinery manufacturing and other fields。

2、Pit type automatic quenching furnace structure

The Pit type automatic quenching furnace structure is introduced as follows:

1. ventilation system

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

2. convection chamber

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

3. Radiation chamber

The heat load of the main place for Pit type automatic quenching 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. ventilation system

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

5. 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、Working principle of Pit type automatic quenching furnace

Pit type automatic quenching furnaceat the start of the operation,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.，it can be used in surface treatment, electron, pharmacy, shipping, automobile and other industries，the main features are Strong adaptability, Easy to control, energy-efficient, Stable and reliable and energy saving and environmental protection。
