| Abstract: | Phase transformation of non-quenched steel cooling after rolling is studied by finite element method on basis of commercial software MSC. MARC. The research focus on the influence of different specifications and cooling rates on microstructure evolution of non-quenched steel. The results show that the ferrite fraction and grain sizes increase and pearlite fraction decrease when product size increase and cooling rate decrease, which provided foundation for controlling of production technology. |
