The sintered layer temperature state detection is a key process in many metallurgical industries to ensure the stability of product quality and reduce the losses caused by temperature change. This article will discuss the importance of temperature monitoring in the sintered layer and the main methods used in the process.
Sintering is a powder metallurgy process used to compact a metal powder in a die and heat it until it is nearly completely solid. During the sintering process, high temperatures are required to achieve maximum welding strength and physical properties of the sintering layer. The temperature of the sintered layer must be carefully monitored in order to maintain the desired structure and properties. If the temperature is too low, the sintered layer cannot be formed properly and weak properties are obtained, while if the temperature is too high, the sintered layer may be too soft or deformed.
Temperature monitoring and detection in the sintering layer is essential to avoiding serious consequences of temperature fluctuations. Temperature control and detection can be done in several ways. Infrared imaging is a non-contact technology used to measure the temperature distribution of the sintered layer in real time. The infrared camera can detect changes in temperature by reading the infrared radiation emitted by the sintered layer. This can help operators detect hotspots and other temperature anomalies in the sintered layer.
In addition to infrared imaging, another popular method for temperature monitoring in the sintered layer is thermal sensing of the material. Thermal sensors are installed within the sintered layer to measure temperature and provide an instant warning when it exceeds a pre-defined threshold. These sensors collect real-time data that can be analyzed and used to detect any changes in temperature of the sintered layer.
Other methods of temperature monitoring in the sintered layer include laser measurement and thermocouple sensors. Laser measurement is a time-of-flight technique that uses a laser beam to measure the distance between the source and the target. This method is more precise than other methods, but it is also more expensive. Thermocouple sensors use two metal wires to measure temperature by measuring the voltage difference between them. This method is more accurate than laser measurement, but it is also more difficult to use.
In summary, temperature monitoring and detection in the sintered layer is essential to ensuring the stability of product quality and reducing the losses caused by temperature change. Many methods are available for temperature monitoring, including infrared imaging, thermal sensing of the material, laser measurement and thermocouple sensors. Using these methods, operators can easily detect temperature changes and take corrective action to maintain the desired sintered layer properties.
