Application of non-contact thermometer in steel processing and manufacturing
Using non-contact infrared thermometers in steel production, temperature monitoring is essential to improve productivity and product quality and product quality. Every stage in the steel production process benefits from non-contact infrared thermometers
1. Application in continuous casting: to accurately monitor temperature to maintain proper metallurgical properties, improve product productivity, improve product quality, and extend equipment life
2. Application in rod/wire rolling: use infrared thermometer to control proper cooling to ensure correct metallurgical properties
3. Application in cold/hot rolling: automatic setting of rolling mill equipment through infrared thermometer, real-time temperature measurement and bracket adjustment. This ensures that the brackets are set properly to match the temperature of the steel
4. Application in heat treatment: Use an infrared thermometer to continuously measure the entire temperature and efficiency of the heater to save fuel and improve product quality.
There are a few important things to remember when using an infrared thermometer
1. Only the surface temperature is measured, and the infrared thermometer cannot measure the internal temperature.
2. The temperature cannot be measured through glass. Glass has very special reflection and transmission characteristics, and infrared temperature readings are not allowed. But the temperature can be measured through the infrared window. Infrared thermometers are best not used for temperature measurement on shiny or polished metal surfaces (stainless steel, aluminum, etc.).
3. Locate the hot spot. To find the hot spot, the instrument aims at the target, and then scans up and down on the target until the hot spot is determined.
4. Pay attention to environmental conditions: steam, dust, smoke, etc. It blocks the optical system of the instrument and affects temperature measurement.
5. Ambient temperature. If the infrared thermometer is suddenly exposed to an ambient temperature difference of 20 degrees or higher, allow the instrument to adjust to the new ambient temperature within 20 minutes.、
