What is a Pit type quenching and annealing furnace? Introduction to the advantages and characteristics of Forging furnace functions

Pit type quenching and annealing furnaceIt is a forging heating device using gas as fuel.，can be customized according to user's needs.。The following is to introduce the Pit type quenching and annealing furnace:

1、Brief introduction of Pit type quenching and annealing furnace

Pit type quenching and annealing furnaceIt is a kind of equipment that uses natural gas as fuel to heat metal materials and make them reach forging temperature.，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 has the functions of Forging heating, normalizing, heat treatment, hardening and tempering and anneal。

3、Pit type quenching and annealing furnace principle

Pit type quenching and annealing 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.，the product looks beautiful.，it mainly includes ventilation system, convection chamber, furnace chamber, Radiation chamber and convection chamber。

5、Structural advantages of Pit type quenching and annealing furnace

The Pit type quenching and annealing furnace has the following structure

1. Radiation chamber

The heat load of the main place for Pit type quenching and annealing 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.

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. furnace chamber

A space for holding metallic materials for heating.

4. combustor

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

5. Radiation chamber

The heat load of the main place for Pit type quenching and annealing 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.

Pit type quenching and annealing furnaceThe 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.、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.、Adopting advanced combustion technology and materials, it has a long service life and low maintenance cost.、Efficient combustion and waste heat recovery system can significantly reduce energy consumption, thus reducing operating costs.、Uniform heating and precise control can be realized, so it is helpful to improve the product quality and yield of metal materials.，the principle is simple.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.，It is an efficient, energy-saving and environment-friendly metal heating device.。
