Abstract: Stress-versus-strain curve of SWRCH22A cold heading steel was determined via a Gleeble-3800 thermal simulation tester. The 1 to 14 passes of the rough rolling and intermediate rolling stages of SWRCH22A steel was simulated on the basis of Deform finite element simulation software. The effects of starting rolling temperatures of 1 010,1 060 and 1 100 ℃ on the rolling force and temperature of rolled piece for SWRCH22A steel were investigated. The results indicated that（a） with the rise in starting rolling temperature,SWRCH22A steel decreased in the rolling force;（b） the rolling force of the 3^rd pass during rolling process starting at 1 010 and 1 100 ℃ was larger than that of the 2^ndpass and instable;（c） the rolling force of 2^nd and 3^rd,6 and 7^th,and 10^th and 11^th passes during rolling process starting at 1 060 ℃ reduced significantly and was relatively stable;（d）the temperatures of rolled piece decreased markedly in edge and had no evident change in core;（e）the increases in roll opening,groove height and spread for 2^nd and 3^rdpasses were able to make rolling process significantly stable; and（f） the most preferable starting rolling temperature was 1 060 ℃ for SWRCH22A cold heading steel.
