Effect of Phosphorus on Sulfide Precipitation in Strip Cast Low Carbon Steel

Yoshinao Kobayashi; Zhongzhu Liu; Kotobu Nagai

The effect of phosphorus addition on sulfide precipitation for strip casting low carbon steel containing copper was investigated and discussed with respect to the morphology, size and composition of sulfide. Both experimental results and mathematical calculation showed that the addition of phosphorus retards the sulfide precipitation at high temperature, promotes the supersaturation of sulfur and makes more copper bearing and smaller sulfide at low temperature. Phosphorus also promotes sulfide precipitation in α-Fe instead of in γ-Fe, so that with high cooling rate small and spherical copper sulfide forms instead of copper sulfide with a plate-like shape.
