Study on Non-Metallic Inclusion in 82B Steel Continuous Casting Billet

Abstract:

The amount, size, composition and source of the inclusion in 82B continuous casting billet was studied by means of electrolysis, anode slime separating, sieve grading and X-ray powder diffraction to lower the amount of non-metal inclusion and to increase the quality of steel. The results show that the total amount of inclusions is up to 183.8ppm where the particle sizes of 75.11% inclusions are smaller than 10μm, and the inclusions are mainly composed by the FeO precipitated in the front of steel billet solidification, and the manganese sulfide and the composite oxides such as calcium and/or silicon aluminates developed by desulphurizing and deoxidizing operation.
