What is a Pressure type annealing furnace? Introduction to the principle of Forging furnace structure

Pressure type annealing furnaceIt is a forging heating device using gas as fuel.，Widely used in Metal melting and casting, Energy conservation and environmental protection, Metal heat treatment, Metal forging heating and Improve production efficiency。The following is to introduce the Pressure type annealing furnace:

1、Brief introduction of Pressure type annealing furnace

Pressure type annealing furnaceIt is a kind of equipment that uses natural gas as fuel to heat metal materials and make them reach forging temperature.，the advantage is Suitable for forging and heating of various metal materials, including steel, aluminum and copper. At the same time, it can also be used in metal heat treatment, tempering and other technological processes.、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 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.、Usually equipped with intelligent control system, it can automatically adjust the parameters such as gas supply and air flow according to the heating demand, and realize accurate control of the temperature and atmosphere in the furnace.，is a common Pressure type annealing furnace。

2、Pressure type annealing furnace use

The purpose of Pressure type annealing furnace is introduced as follows:

1. Energy conservation and environmental protection

The Pressure type annealing 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 forging heating

The Pressure type annealing 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.

3. Metal melting and casting

Although it is mainly used for forging heating, some types of Pressure type annealing 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 Pressure type annealing 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. Improve production efficiency

The Pressure type annealing furnace has the advantages of fast heating speed and accurate temperature control, which can improve production efficiency. This is especially important for mass-produced forging workshops.

3、Structural characteristics of Pressure type annealing furnace

The Pressure type annealing furnace structure is introduced as follows:

1. 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.

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. Radiation chamber

The heat load of the main place for Pressure type 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.

5. ventilation system

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

5、Pressure type annealing furnace function

Pressure type annealing furnacemultifunctional, with functions such as hardening and tempering, temper, normalizing, hardening and tempering and Casting heating，at 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.，customizable。
