Effect of hot-rolling parameters on microstructure and mechanical properties of 72LXA steel wire rod
Effect of the laying head temperature and controlled cooling process on microstructure and mechanical properties of 72LXA wire rod were investigated.The results show that under the same cooling process,with the raising laying temperature and increasing sorbitizing rate and decreasing proeutectoid ferrite,the steel rod strength is improving,proeutectoid ferrite and sorbitizing rate are the critical impact factors on steel rod properties; indentifying cooling after perlite forming can restrain the dissolve of lamellar cementite; the mechanical properties of whole rod coil are improved by the proper rolling rate and air cooling.The high strength of 1050 MPa of steel rod was obtained,that shows the defined hot rolling process can conform to the steel rod properties requirement.
