DEVICE AND METHOD FOR CONTACTLESS RECOGNIZE AT LEAST ONE POINT ERRORS AND / OR AT LEAST ONE DIMENSION TO A WARM TRAIN CAST MATERIAL

摘要

There is shown an apparatus and method for the contactless detection of at least one error location (10) and / or at least one dimension in a warm continuously cast material (2), in particular a hot slab (21), a casting plant (12), preferably a continuous casting, wherein at least partially on the surface (4) of the continuously cast material (2) at least one camera (3) for sensor data acquisition of at least infrared radiation having electromagnetic radiation is optically directly and / or addressed indirectly and at least this recorded sensor data on the fault location (10) and / or is inferred the dimensions at the continuously cast material (2). In order to obtain advantageous process characteristics, it is proposed that the electromagnetic radiation in a near infrared radiation (NIR) is optically limited before this radiation of the sensor data of the recording camera (3) is supplied.
