Advanced Energy ’ s Impac ® pyrometers address challenges in temperature monitoring of the pouring stream in castings made of different alloys
In most foundries , the temperature of the metal melt is typically measured by thermocouple immersion probes . These immersion measurements can only be made in the crucibles or the transfer ladles where the melt is stationary , but not in the pouring stream where insertion of a probe would disturb the flow into the cast . However , the direct temperature of the pouring stream is critical to the quality of the final casting . Continuous monitoring of the pouring steam temperature and pour quality enables better control of the casting process .
Accurate and undisturbed temperature measurement of the pouring stream can only be obtained by non-contact measurement via pyrometers . When castings are made of different alloys , conventional pyrometers and ratio pyrometers often cannot be used to measure the pouring stream due to considerable differences in measuring conditions and metal characteristics .
Due to extremely high ambient heat , fixed measurement systems require rugged industrial designs to overcome the challenges that hinder accurate temperature measurement of the pouring steam – from changes in stream location and width , start and stop time variation , as well as slag interference .
Advanced Energy ’ s specialized Impac ® pyrometer solutions address these challenges and provide robust and accurate temperature measurement by using a special measurement system for this application . The Impac ISR 12-LO / GS measures the exact casting temperature of each pouring process and displays them online . Corrective action can be taken immediately if defined limits are exceeded , which maintains the narrow process window for quality castings .
Designed specifically for accurate measurement of pouring streams , the Impac ISR 12-LO / GS features :
