Method and device for early detection of breakthroughs by strand casting of steel with an oscillating mold

摘要

The method includes a continuous and comparative measurement of operating parameters such as, for example, the temporal and spatial temperature distribution in the copper mould plates, and an analysis of the measured data. Two sets of measured data are combined with at least one further measurement series and are subjected to on-line analysis. The apparatus includes a measurement and analysis system with the following elements: a) at least one oscillations acceleration sensor (10.1-10.4); b) a number of temperature sensors (11) in the mould plates; c) a line camera (12) for detection of billet oscillation; d) a billet velocity sensor (13); e) assessment units (20-22); f) a central computer unit (30); g) a unit (31) for issuing an early warning signal.
