A Technology for Producing Hot Rolled Product of Cold Heading Steel

摘要：

　　In the present paper,thermomechanical controlled processing (TMCP) of low carbon cold heading steel was conducted by a laboratory hot rolling mill.The results have shown that the mechanical properties of the low carbon cold heading steel can be significantly improved by TMCP without heat treatment.The enhancement of the mechanical properties for the low carbon cold heading steel is attributed mainly to the finer ferrite grain size,and it is also related to the remaining dislocations within substructure of the cold heading steel after deformation.A technology is developed for producing hot rolled product of cold heading steel with improved mechanical properties.The technology has great significance because processing flow is simplified,and manufacture cost is decreased.
