Heat treatment is a process used to change the microstructure of metals and other materials. This process usually requires temperature control and is sometimes done under atmosphere control. This atmosphere control is usually applied to prevent unwanted chemical reactions or to achieve a specific surface coating. Vacuum is a frequently used method in atmosphere control.
Control of Atmosphere: ensuring that vacuum is applied properly to prevent unwanted gases or pollutants from reacting with metal must. Vacuum gauges are needed to make sure the atmosphere is suitable.
High Quality: Low vacuum levels can cause undesirable reactions such as undesired oxidation or carburization on the surface of the material. Vacuum gauges can help prevent such defects.
Efficiency: To understand whether the equipment is working efficiently, the vacuum level must be known. If the vacuum is not working properly, this may cause the equipment or system to consume more energy.
Equipment Life: To prolong the life of the equipment, it is important to ensure that the vacuum is applied correctly. Incorrect vacuum levels can damage equipment.
Safety: In some heat treatment processes, high vacuum levels can be dangerous. Therefore, making sure the vacuum is at the correct level is safety critical.
Vacuum meter types include various options such as pirani vacuum meters, ionization vacuum meters and diaphragm vacuum meters. However, vacuum gauges with SRG technology stand out as being resistant to high temperature environments.
This measurement technology works by measuring the drag speed of a rotating rotor. The rotor is dragged by the gas molecules in the vacuum, and this drift rate depends on the density of the gas.
Wide Measurement Range: The SRG is capable of measuring in a wide vacuum range. It is advantageous in many heat treatment applications because it often requires operating at different vacuum levels.
High Precision: SRG technology can measure with high precision even in ultra-high vacuum regions. High vacuum zones are a critical factor for achieving the best results during heat treatment.
Gas Type Insensitivity: Unlike many other vacuum gauge technologies, the SRG's measurement accuracy is not dependent on the type of gas. This allows consistent measurements when working with different gases.
Low Maintenance: SRGs are generally durable and have low maintenance requirements, providing long-term cost savings.
Unaffected by Pollution: Spinning rotor gauge technology is not easily affected by pollution or gas residues. It offers the advantage of obtaining accurate measurements even in dense gas atmospheres that occur during heat treatment.
Simple and Direct Measurement: SRG technology is based on simple physical principles and requires less calibration than other technologies. It means convenience and reliability for the user.
In heat treatment applications, maintaining the correct vacuum levels is critical to optimize material properties and ensure product quality. Therefore, using a reliable and precise vacuum measurement technology such as SRG is essential for process control and offers great advantages for quality assurance.
