Abstract

The variation of dissolved calcium content after calcium treatment in 37Mn5 pipeline steels was investigated. The content of [Ca] was calculated based on measured results of T.Ca and the composition of inclusions, which decreased from 16 to 0.07 ppm due to calcium vaporization. A comparison between the calculated and predicted [Ca] contents using Factsage indicated a good agreement. The effect of T.Ca, T.O., T.S, [Al]s, and temperature on [Ca] was also discussed.
