METHOD AND DEVICE FOR DETERMINING CHARACTERISTIC TEMPERATURES OF STEEL TAKEN DIRECTLY FROM A TUNDISH

摘要

The objective of the present invention is to provide a device and a method which assure accurate and repeatable continuous temperature measurements of steel melt during its solidification when sampling from a tundish in a steel mill using a continuous casting process. The device comprises a measuring cup (2), a protecting element (3), a cup protection element (5), a funnel (6), a holder, a housing protected by a cardboard tube, a thermocouple with a ceramic connector, and a rod to house a compensating cable with a plastic connector. All parts of the device with the exception of the protecting element (3), the cup protection element (5), and the funnel (6) are reusable. The method for determining characteristic temperatures of the liquid steel comprises steps of preheating the measuring cup (2) of the device and covering the steel melt in the measuring cup (2) with a layer of exothermic powder.
