The Relationship

A new method for the determination of inclusions of boron and titanium in medium and low alloy steel has been reported in this paper. The technique of original position statistic distribution analysis based on statistic analysis of more than ten thousands primary optical signals is applied in the present method. It is found that the abnormal high intensities in emission lines of boron and titanium occurred when a discharge volatilizes the material containing inclusions of boron and titanium. Some statistic algorithms are developed to distinguish the signals related to nonmetallic inclusions from the signals generated from soluble boron and titanium. Furthermore, mathematical models based on the relationship between the frequency of abnormal sparks and content of inclusions is put forward in this paper to count the contents of inclusions of boron and titanium. The results calculated by the present model have good coincidence with the value obtained by chemical methods. The present method has been applied to the determination of the contents of inclusions of boron and titanium in some certified reference materials and some real medium and low alloy steel samples.

Continuous Casting Billet

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.

AbstractIn this study, the parameters of 44 sticker breakout samples were analysed. The research mainly focused on the steel grades and slab thickness of stickers. Other processing parameters, such as slab width, casting speed, mould fluctuation, heat flux and operation, were also discussed. The results show that the number of stickers of low carbon steel and low alloy steel was 16 and 28, respectively. The stickers of low carbon steel were less than those of low alloy steel regardless of the thickness and width. The ratio of stickers per 1,000 casting heats of 220, 260 and 320 mm thickness slabs was 2.5, 0.5 and 0.6, respectively. The higher casting speed of 220 mm thickness slabs made the casting status unsteady and caused more stickers. From the perspective of width, the stickers were gradually increased along with the increase in width due to the worse mould slag. This study provides a foundation to reduce slab stickers and is helpful for a more efficient technology of continuous casting.
