QUALITY MONITORING DEVICE AND QUALITY MONITORING METHOD FOR CONTINUOUS CAST CAST SLAB

PROBLEM TO BE SOLVED: To provide a quality monitoring device which determines the amount of inclusions in cast slabs in real time for every cast slabs by taking the information on the refining process of molten steel which is the upper stream process of a continuous casting process into consideration as well. SOLUTION: The problem described above is solved by the quality monitoring device for the continuous cast slabs provided with a means 8 for finding the determination standard for the amount of the deoxidation product produced in the refining process for molten steel, a means 8 for finding the determination standard for the floating amount of the inclusions within a tundish of a continuous casting process, a means 8 for finding the determination standard for the entangling amount of the mold powder within the casting mold of the continuous casting process, a means 8 for deciding whether the rolling of the cast slab in an unmended state is permissible or not by comparing the above three found determination standards with acceptance standard for the cast slab quality.
