Why the Vacuum Gas Quenching Furnace is Popular?

In the field of modern industrial manufacturing, heat treatment technology has always occupied a pivotal position as a key link in enhancing material properties and optimizing product quality.

As technology advances and manufacturing processes continue to improve, vacuum gas quenching furnaces are becoming the first choice for many industries.

Brother Furnace's vacuum gas quenching furnaces have received a large number of favorable comments from customers since they were released.

Why are they becoming more and more popular? This article will delve into the answer to this question from several perspectives.

Working Principle of Vacuum Gas Quenching Furnace

The vacuum gas quenching furnace is a commonly used equipment for metal processing and heat treatment. Its main principle is to use the vacuum environment at high temperatures and gas quenching so that the metal materials in the heating and cooling process get the effect of strengthening and improving performance.

1. Creating a Vacuum Environment:

Firstly, the air inside the furnace chamber is pumped out by a vacuum pump, to achieve a certain degree of vacuum. In this way, the number of gas molecules in the furnace is reduced and the resistance to heat and mass transfer is lowered.

2. Heating the Workpieces

Under vacuum, heating elements (e.g. graphite heating elements as well as molybdenum foil heating elements) are used to heat the workpieces to a predetermined quenching temperature.

In this process, the presence of a vacuum environment effectively avoids oxidization and decarburization of the workpiece during the heating process.

3. Rapid Cooling

When the workpieces reach the quenching temperature, high-purity inert gases (e.g. nitrogen, helium, etc.) are rapidly introduced to the workpieces for rapid cooling. This step is the core of the vacuum quenching furnace work.

Rapid cooling changes the organizational structure of the workpiece, to improve the hardness, strength and wear resistance, and other properties of the workpieces.

Technical Advantages

The vacuum gas quenching furnace is widely popular, mainly due to the unique technical advantages of the Brother Furnace:

1. Uniform Temperature Distribution

In a vacuum environment, the transfer of heat mainly relies on radiation and conduction, and there is no convection phenomenon. This heat transfer makes the temperature distribution in the chamber of the gas quenching furnace more uniform, thus ensuring the consistency and stability of the workpieces during the heating process. This is important for improving the quality and consistency of products.

2. Low Oxidation and Decarburisation Rate

The vacuum system of the vacuum quenching furnace effectively isolates the erosion of oxygen and other active gases on the workpieces, which greatly reduces the oxidation and decarburization of the workpieces during the heating process.

This is essential to maintain the surface quality and stability of the chemical composition of the workpieces. Especially when dealing with high-purity materials or products requiring high surface finish, the advantages of the vacuum gas quenching furnace are especially obvious.

3. Efficient Cooling Effect

Brother Furnace's gas quench furnaces use high-purity inert gas as the cooling medium, which is not only clean and pollution-free but also fast and efficient. This efficient cooling can quickly change the organization of the workpieces and improve their properties.

At the same time, due to the uniform distribution of the cooling medium, quality problems such as deformation and cracking caused by uneven cooling are avoided.

4. Wide Applicability

This furnace is capable of handling many types of metal materials, including high-speed steel, tool steel, mold steel, stainless steel and so on. Its efficient quenching capability and precise temperature control make it widely used in many fields such as aerospace, automotive manufacturing, mold making and so on.

5. Environmental Protection and Energy Saving

The vacuum gas quenching furnace does not produce pollutants during the working process, which meets the requirements of modern industry for environmental protection and energy saving. At the same time, due to its efficient heating and cooling system, it can significantly reduce energy consumption and improve production efficiency.

Which Fields Need Vacuum Gas Quenching Furnaces?

With its unique technical advantages, the vacuum gas quenching furnace shows a wide range of application prospects in many fields:

1. Mold Manufacturing

Mold is an important tool in industrial production, and its performance directly affects the quality of products and production efficiency. Vacuum gas quenching furnace can provide efficient quenching treatment for mold steel, significantly improving the hardness, wear resistance, and service life of the mold.

At the same time, due to the existence of a vacuum environment, the oxidation and decarburization of the mold in the heating process are avoided, and the surface quality and precision of the mold are maintained.

2. Aerospace

The aerospace field has extremely high requirements for material performance, requiring materials with high strength, high toughness, corrosion resistance. and other characteristics.   

Vacuum gas quenching furnace can carry out precise heat treatment for aerospace materials, improve their organizational structure, and enhance their comprehensive performance. At the same time, the existence of a vacuum environment avoids oxidation and pollution problems in the heating process of the material, ensuring the quality and reliability of the product.

3. Automobile Manufacturing

Vacuum gas quenching furnace can provide efficient quenching treatment for automotive parts to improve their hardness, strength and wear resistance. On the other hand, it also avoids the oxidation and deformation problems of the parts during the heating process, and ensures the precision and consistency of the products.

4. Precision Machinery

The recision machinery industry requires high precision and performance of products. Vacuum gas quenching furnace can be precise heat treatment of precision machinery parts, and improve their organizational structure and performance. The uniform distribution of the cooling medium and efficient cooling effect avoids the deformation and cracking of the parts in the quenching process, to ensure the precision and quality of the product.
