The continuous cooling transformation ( CCT) curves of deformed austenite of V microalloying steel SWRH82B-1V (% : 0. 79C
0. 23Si
0. 63Mn

0.004 ON) were measured by thermal simulator Gleeble 2000 and the effect of cooling rate (1 〜15 °C/s) on area fraction of sorbite and martensite in steel and HV hardness value of the steel was studied. And the effect of percentage of cooling wind at Stelmor production line on structure and mechanical properties of Φ12. 5 mm wire coil of steel SWRH28B-1V was studied by changing cooling mode. Results show that as the outlet temperature of finishing coil is 880 T
cooling with 50% wind rate
the area fraction of sorbite and martensite in the steel is respectively ≥90% and ≤0. 05%
and the tensile strength of the coil is ≥l 130 MPa while its area of reduction is ≥30%.
