1、Brief introduction of Pit type hot-dip galvanizing furnace

Pit type hot-dip galvanizing 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.，at work,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.，the product looks atmospheric.，is a Pit type hot-dip galvanizing furnace，It is mostly used in Metal heat treatment, Metal melting and casting, Metal tempering, Improve production efficiency, Energy conservation and environmental protection, Metal heat treatment and so on。

2、Advantages of Pit type hot-dip galvanizing furnace principle

Pit type hot-dip galvanizing furnacein the course of work,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.，can be customized according to user's needs.。

4、Structural advantages of Pit type hot-dip galvanizing furnace

The Pit type hot-dip galvanizing furnace has the following structure

1. combustor

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

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. 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.

4. Radiation chamber

The heat load of the main place for Pit type hot-dip galvanizing 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、Introduction of Pit type hot-dip galvanizing furnace characteristics

Pit type hot-dip galvanizing furnace has the following characteristics

1. energy saving and environmental protection

As a clean energy source, gas produces less waste gas and waste smoke after combustion, which is beneficial to environmental protection. At the same time, some Pit type hot-dip galvanizing furnaces are also equipped with waste heat recovery system, which further improves the energy utilization efficiency.

2. energy saving and environmental protection

Natural gas is a kind of clean energy, which produces less waste gas and waste smoke after combustion and has little environmental pollution. At the same time, through wall regenerative combustion technology, flue gas waste heat recovery system and other technical means, the Pit type hot-dip galvanizing furnace further improves energy utilization efficiency and reduces energy consumption and emissions.

3. Stable and reliable

The Pit type hot-dip galvanizing furnace has a stable combustion system and temperature control system, which can ensure the uniformity and stability of the temperature in the furnace, thus improving the quality and production efficiency of forged products.

4. Strong adaptability

Pit type hot-dip galvanizing furnace

Pit type hot-dip galvanizing furnacethe principle is simple.Heat of combustion based on fuel. Fuel gas (such as natural gas, liquefied petroleum gas, etc.) is mixed with combustion-supporting air through the burner and burned to produce high-temperature flame and flue gas. These high-temperature flames and smoke exchange heat with metal materials in the furnace, so that they gradually heat up to the temperature required for forging.，the advantage is 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.、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.、Natural gas is mainly used as fuel, but some equipment also supports other types of gas or liquid fuel, which has strong fuel adaptability.、Adopting advanced combustion technology and control system can realize full combustion of natural gas and improve combustion efficiency. At the same time, some equipment is also equipped with waste heat recovery system, which can further recycle the waste heat in exhaust smoke and improve energy utilization efficiency.。
