Research of A High Strength Non-Quenched and Tempered Steel for Fracture Splitting Connecting Rod of Automobile
Journal Title: Automobile Technology & Material - Year 2024, Vol 39, Issue 3
Abstract
It is concluded in this research that strength and toughness of steel can be significantly improved by precipitation strengthening and fine-grained strengthening after adding trace alloying elements of V, Nb and Ti in steel and combining with C and N in steel. Based on the thermodynamic calculation software, the V, Nb and Ti composite microalloying design of non-quenched & tempered 46MnVS6 steel was realized. At the same time, the rolling heating process dissolved the liquid phase of the large particles and realized the high strength design of the material. In addition, the special slag system of non- quenched & tempered steel with low and medium basicity was developed through the simulation calculation of refining slag system, which ensured the precise control of S element in the refining process. The results show that non- metallic inclusions control in non- quenched & tempered steel and the sulfide morphology are optimized, and cutting performance of the material is improved.
