Introduction to Double chamber high-temperature annealing furnace, forging furnace advantages, characteristics and principles

Double chamber high-temperature annealing 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.，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 product looks beautiful.。

1、Brief introduction of Double chamber high-temperature annealing furnace

Double chamber high-temperature annealing furnaceIt is a kind of equipment that uses natural gas as fuel to heat metal materials and make them reach forging temperature.，multifunctional, with functions such as Casting heating, Casting heating, normalizing, hardening and tempering and temper，Mainly used forEnergy conservation and environmental protection,Improve production efficiency,Metal tempering,Metal forging heating andEnergy conservation and environmental protection，the advantage is 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.、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.、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 materials, it has a long service life and low maintenance cost.、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.，the main features are energy saving and environmental protection, Strong adaptability, Easy to maintain, energy-efficient and Strong adaptability。

2、Structural characteristics of Double chamber high-temperature annealing furnace

The Double chamber high-temperature 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. ventilation system

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

3. furnace chamber

A space for holding metallic materials for heating.

4. convection chamber

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

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.
