摘要：
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 produces more copper bearings and smaller sulfides at low temperature. Phosphorus also promotes sulfide precipitation in a-Fe instead of in g-Fe, so that small spherical copper sulfides form at a high cooling rate instead of plate-like shaped copper sulfides.
