Ductile iron was first developed in 1943 and it is widely used in automotive industry.the difference between cast iron and ductile iron is due to the presence of spheroid graphite in the matrix of ductile iron which is not found in brittle cast iron. ductile iron possesses higher ductility and tensile strength than in cast iron. it is inexpensive and castability compared to steel.

Dephosphorization is one of key goals for converter to smelt high carbon steel. the chemical equation of dephosphorization reaction and the expression of phosphors distribution between slag and steel were deduced on fundamental of metallurgical thermodynamics and the steelmaking situation of shougang shuicheng iron and steel group co. ltd.
Welding of ductile iron since the invention of ductile iron dl in 1948, the weldability of ductile iron alloys has been studied and many papers on the subject have been published. despite the extensive investigation of welding of dl, there continues to be disagreement over whether the material is quotweldablequot or quotunweldable.quot much of
The material used in this investigation was a ductile cast iron relatively free from alloying elements. the chemical composition of the material in weight percentage is reported in table 1. the material was cast in the form of keel blocks and from these
