Abstract

Abstract

The producing process and properties of subway wheel steel ER7 is researched with the routine of LD-LF-VD-CC,by micro-alloying of vanadium and chromium,calcium treatment and sulfur wire-feeding.Carbon segregation,center porosity and shrinkage cavity was effectively improved by steel superheat,second cooling and F-EMS parameter control. The properties of steel,such as the strength,ductility,plasticity and anti-fatigue is qualified.
