1、Brief introduction of Pit type high-temperature annealing furnace

Pit type high-temperature annealing furnaceIt is an efficient, energy-saving and environment-friendly metal heating device.，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 heat treatment, Casting heating, hardening and tempering, anneal and quench，is a Pit type high-temperature annealing furnace，the product looks beautiful.。

3、Pit type high-temperature annealing furnace principle

Pit type high-temperature annealing furnaceHeat 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.，features include Easy to maintain, Easy to control, Strong adaptability, energy-efficient and Stable and reliable，It is a kind of equipment which uses gas as fuel and is specially used for heating metal before forging.，multifunctional, with functions such as hardening and tempering, Casting heating, temper, heat treatment and hardening and tempering，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.、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.、The metal material can be heated to the required temperature in a short time, and the production efficiency is improved.、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.、Natural gas is used as a heat source, resulting in less waste gas and smoke after combustion, and less pollution to the environment. This will help reduce industrial emissions and improve the atmospheric environment.。

5、Pit type high-temperature annealing furnace structure

The Pit type high-temperature annealing furnace structure is introduced as follows:

1. furnace chamber

A space for holding metallic materials for heating.

2. Waste heat recovery system

Recover the waste heat in the exhaust gas of heating furnace to improve the energy utilization efficiency.

3. ventilation system

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

4. Radiation chamber

The heat load of the main place for Pit type high-temperature 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.

6、Structural characteristics of Pit type high-temperature annealing furnace

The Pit type high-temperature annealing furnace has the following structure

1. Radiation chamber

The heat load of the main place for Pit type high-temperature 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. 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. 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.

5. ventilation system

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

Pit type high-temperature annealing furnaceNatural gas is mainly used as fuel, but some equipment also supports other types of gas or liquid fuel, which has strong fuel adaptability.、Uniform heating and precise control can be realized, so it is helpful to improve the product quality and yield of metal materials.、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.、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.、It can improve the plasticity and fluidity of metal materials, reduce the difficulty and cost of forging, and improve product quality and production efficiency.，is a kind of high quality and low price Pit type high-temperature annealing furnace，It is a forging heating device using gas as fuel.。
