Sulphide capacity calculation and desulphurization analysis of ultra low oxygen spring steel

The sulphide capacity of ultra low oxygen spring steel during manufacture process was calculated by KTH model, Young's optical basicity model and Tsao's empirical formula etc, and the sulphur distribution L_S in production process was forecast by applying Turkdogan's and Hino's equations. The predicted values of sulphur distribution were contrasted with actual measured results and a comparatively accurate model for forecasting L_S of ultra low oxygen spring steel was proposed.
