Introduction to Cylindrical tube annealing furnace and forging furnace working principle

Cylindrical tube annealing furnaceIt is a kind of equipment which uses gas as fuel and is specially used for heating metal before forging.，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.，it has the functions of quench, Casting heating, heat treatment, anneal and normalizing，is a popular Cylindrical tube annealing furnace，support customization。The following is to introduce the Cylindrical tube annealing furnace:

1、Brief introduction of Cylindrical tube annealing furnace

Cylindrical tube annealing furnaceIt is a kind of equipment that uses natural gas as fuel to heat metal materials and make them reach forging temperature.，It is mostly used in Metal heat treatment, Metal forging heating, Metal melting and casting, Metal forging heating, Improve production efficiency, Metal heat treatment and so on，it has been widely used in pharmacy, material, electron, metallurgy, automobile and other industries。

2、Cylindrical tube annealing furnace characteristics

The Cylindrical tube annealing furnace features are as follows:

1. Strong adaptability

The Cylindrical tube annealing furnace can be used for forging and heating of bar, round steel, square steel, steel plate and other metal materials, and has a wide range of applications.

2. Easy to maintain

The structural design of the Cylindrical tube annealing furnace is reasonable and easy to maintain, which reduces the operating cost and failure rate of the equipment.

3. Efficient heating

The Cylindrical tube annealing furnace can heat the metal material to the required temperature in a short time and improve the production efficiency.

4. Easy to control

The combustion system and ventilation system of the Cylindrical tube annealing furnace can be adjusted as required to accurately control the temperature and atmosphere in the furnace and meet the heating requirements of different metal materials.

5. 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 Cylindrical tube annealing furnaces are also equipped with waste heat recovery system, which further improves the energy utilization efficiency.

3、Cylindrical tube annealing furnace principle

Cylindrical tube annealing 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.，features include Easy to maintain, Stable and reliable, Strong adaptability, energy-efficient and Easy to control。

4、Cylindrical tube annealing furnace structure

The Cylindrical tube annealing furnace structure is introduced as follows:

1. convection chamber

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

2. combustor

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

3. furnace chamber

A space for holding metallic materials for heating.

4. Radiation chamber

The heat load of the main place for Cylindrical tube 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. 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.
