Abstract
TWIN ROLL CASTING OF THIN STEEL STRIP.MOLTEN STEEL IS INTRODUCED BETWEEN A PAIR OF COOLED CASTING ROLLS TO FORM A CASTING POOL FROM WHICH STEEL SOLIDIFIES ON THE ROLLS TO PRODUCE A SOLIDIFIED STRIP. THE MOLTEN STEEL HAS A TOTAL OXYGEN CONTENT IN THE RANGE 100PPM TO 250PPM AND CONTAINS METAL OXIDE INCLUSIONS COMPRISING ANYONE OR MORE OF MNO, SiO2 AND A12O3 DISTRIBUTED THROUGHOUT THE STEEL AT AN INCLUSION DENSITY IN THE RANGE 2GM/CM3 TO 4GM/CM3. TYPICALLY THE INCLUSIONS RANGE IN SIZE BETWEEN 2 AND 12 MICRONS. THE CAST STRIP HAS A THICKNESS OF LESS THAN 5MM AND CONTAINS SOLIDIFIED METAL OXIDE INCLUSIONS DISTRIBUTED SUCH THAT THE REGIONS OF THE STRIP CONTAIN SOLIDIFIED INCLUSIONS TO A PER UNIT AREA DENSITY OF AT LEAST 120 INCLUSIONS/MM2.(FIG 2)
