Today the mold thermal mapping technology is typically applied to the CCMs for slabs with solutions based on the installation of thermocouples (TC) or optical fibre cables (OFC), inserted into channels machined in the plate molds. The final installation is complex since every single mold must be machined and the quantity of cables is considerable, making any mold change a complex and time-consuming activity. Extending TC or OFC application to billets and blooms would require invasive and expensive CNC machining of the curved mold tubes. In order to overcome these limits, Ergolines designed a new system based on contactless ultrasound technology, which provides the real-time mold thermal map without the need to machine the copper, offering a new reliable tool also to the CCMs for small sections. By providing real-time data of the thermal distribution of the mold, Ergolines’ system can be fruitfully used by the technical personnel to improve the casting practice, the steel quality and the plant productivity.
