METHOD FOR CONTROLLING SUPPLYING MOLTEN METAL QUANTITY AT THE TIME OF CONTINUOUSLY CASTING WIDE AND THIN CAST SLAB

摘要

PURPOSE: To enable the suitable control of supplying molten metal quantity at the time of continuously casting a wide and thin cast slab and to stably produce the thin cast slab. ;CONSTITUTION: At the time of continuously casting the wide and thin cast slab, the supplying molten metal quantities from two immersion nozzles 1 arranged side by side in the width direction of a mold 2 are controlled. Molten metal surface level meters 4 are arranged side by side at the short wall sides of the mold in two immersion nozzles 1 to detect the molten metal level in the mold and at the time of judging the biased flow from the detected values of both molten metal surface level meters 4, the opening degrees of sliding nozzles arranged in two immersion nozzles 1 are adjusted so as to prevent the biased flow.;COPYRIGHT: (C)1996,JPO
