Wen Yang, Lifeng Zhang, Xinhua Wang, Ying Ren, Xuefeng Liu, Qinglin Shan.Characteristics of inclusions in low carbon Al-killed steel during ladle furnace refining and calcium treatment. ISIJ International, 2013, 53(8): 1401-1410. [4] Wen Yang, Xinhua Wang
The results indie that cooling with scrap after the calcium treatment worsen the steel cleanliness in terms of non-metallic inclusions and should therefore be avoided. Furthermore, multiple of small aluminum additions late in the process is likely a contributing parameter to increase the projected length of the inclusions.

countered. According to analysis based on the steel ingots containing 0.01-0.15% sulfur, the morphology is typically clas-sifi ed into three types: a. Type I are silicon-killed steels (or steels incompletely killed with aluminum, zirconium or titanium). MnS arewith a

Calcium Carbonate is the carbonic salt of calcium (CaCO3). Calcium carbonate is used therapeutically as a phosphate buffer in hemodialysis, as an antacid in gastric hyperacidity for temporary relief of indigestion and heartburn, and as a calcium supplement for preventing and treating osteoporosis.
When the steel solidifies, the solubility of oxygen approaches zero. The remaining oxygen in the melt will end up as oxide inclusions. In the Figure 4 are oxygen activity is plotted as a function of steel temperature. Calcium treatment is a countermeasure to avoid
Alumina (Al2O3) inclusions in LCAK steel, and silica (SiO2) inclusions in Si-killed steel are generated by the reaction between the dissolved oxygen and the added aluminum and silicon deoxidants are typical deoxidation inclusions. Alumina inclusions arefigure 4.
