Industrial heat treatment equipment – vacuum furnace

In modern industrial production, the progress of materials science has promoted the development of many fields. Among them, vacuum furnaces, as an important technical means, play an indispensable role in metal processing, semiconductor manufacturing, aerospace and other fields.

Vacuum Furnace Product Overview
A vacuum furnace refers to industrial equipment that performs heating treatment in a high vacuum environment. It achieves the heat treatment process of the workpiece by extracting the air in the furnace to achieve the set vacuum degree. Since under high vacuum conditions, adverse reactions such as oxidation and decarburization can be effectively reduced or even eliminated, the surface quality and internal performance of the workpiece can be improved.

Vacuum Furnace Structure
A vacuum furnace usually includes the following parts: 1. Furnace body: made of high temperature resistant materials, which can ensure the temperature in the furnace while also withstanding certain pressure changes. 2. Heating elements: commonly used are resistance wires, induction coils, etc., which are used to provide heat. 3. Vacuum system: including vacuum pumps, valves, and measuring instruments, etc., to establish and maintain the required vacuum environment. 4. Control system: responsible for monitoring parameters such as temperature and pressure, and adjusting the heating rate and vacuum degree. 5. Cooling system: critical for applications that require rapid cooling, which can be gas or liquid cooling.

Working principle of vacuum furnace
The working principle of vacuum furnace is based on such a principle: when the pressure in the furnace is reduced to a certain level, the gaseous molecules on the surface of the material are reduced, making it difficult for the material to undergo chemical reactions (such as oxidation). At the same time, due to the lack of air convection, heat transfer mainly relies on radiation. This not only can evenly heat the workpiece, but also can accurately control the heating process to achieve high-quality heat treatment effects.

Features and advantages of vacuum furnace
Compared with traditional heat treatment methods, vacuum furnaces have the following obvious advantages: 1. Prevent oxidation and pollution: The high vacuum environment almost eliminates the effects of oxidation and other pollutants. 2. Improve material properties: A purer surface quality can be obtained and the mechanical properties of the material can be improved. 3. Strong controllability: By accurately controlling conditions such as temperature and pressure, more delicate operations can be achieved. 4. Energy saving and high efficiency: Compared with ordinary furnaces, vacuum furnaces often have lower energy consumption and higher efficiency. 5. Wide range of applications: From metal parts to semiconductor devices, suitable vacuum treatment methods can be found.

Vacuum furnaces are widely used in many industries:
1. Metal processing: such as vacuum quenching and vacuum annealing of titanium alloys and stainless steel. 2. Semiconductor manufacturing: used in processes such as crystal growth and thin film deposition. 3. Aerospace: Precision vacuum heat treatment of aircraft parts to improve their corrosion resistance and strength. 4. Medical equipment: A sterile, pollution-free environment is required during the manufacturing process. 5. Scientific research experiments: It is also used in basic research in the fields of materials science, physical chemistry, etc.
