Introduction to Rapid heating quenching furnace, heating furnace advantages, characteristics and principles

Rapid heating quenching furnaceIt is a kind of equipment which uses gas as fuel and is specially used for heating metal before forging.，widely used in surface treatment, machinery, shipping, electron, machinery and other fields，be of high quality，The price is relatively low.。

1、Brief introduction of Rapid heating quenching furnace

Rapid heating quenching furnaceIt is a kind of equipment that uses natural gas as fuel to heat metal materials and make them reach forging temperature.，the main features are Strong adaptability, energy-efficient, Easy to control, Easy to maintain and Stable and reliable，at work,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.，has been favored by more and more customers.。

2、Rapid heating quenching furnace advantage

The advantages of Rapid heating quenching furnace are as follows:

1. Wide application range

The Rapid heating quenching furnace 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.

2. Efficient combustion

The Rapid heating quenching furnace adopts advanced combustion technology and control system, which 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.

3. Reduce operating costs

The efficient combustion and waste heat recovery system of the Rapid heating quenching furnace can significantly reduce energy consumption, thus reducing operating costs.

4. Rapid temperature rise

The Rapid heating quenching furnace can heat the metal material to the required temperature in a short time, which improves the production efficiency.

5. Uniform heating

The Rapid heating quenching furnace adopts regenerative combustion system or advanced burner design, which can realize uniform distribution of temperature in the furnace, ensure uniform heating of metal materials and improve product quality.

3、Rapid heating quenching furnace structure

The Rapid heating quenching furnace structure is introduced as follows:

1. furnace chamber

A space for holding metallic materials for heating.

2. Radiation chamber

The heat load of the main place for Rapid heating quenching 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.

3. combustor

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

4. 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.

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.

4、Rapid heating quenching furnace use

The purpose of Rapid heating quenching furnace is introduced as follows:

1. Metal tempering

By properly heating and cooling the metal material, the Rapid heating quenching 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.

2. Metal heat treatment

In addition to forging heating, Rapid heating quenching furnaces can also be used for metal heat treatment processes, such as annealing and tempering. These processes can improve the microstructure and properties of metal materials, and improve their service life and mechanical properties.

3. Metal forging heating

The Rapid heating quenching 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.

4. Improve production efficiency

The Rapid heating quenching 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.

5. Metal melting and casting

Although it is mainly used for forging heating, some types of Rapid heating quenching furnaces can also be used in metal melting and casting processes. This is especially suitable for melting and casting of small or special alloys.

5、Rapid heating quenching furnace principle

Rapid heating quenching furnaceat runtime,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.，is a common Rapid heating quenching furnace，the product looks atmospheric.，the advantage is 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.、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.、Natural gas is mainly used as fuel, but some equipment also supports other types of gas or liquid fuel, which has strong fuel adaptability.、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.，it is an ideal choice for customers to buy Rapid heating quenching furnace。
