Abstract
The effects on the controlled cooling of hot-rolled wire rod of steel at different ambient temperature and humidity have been investigated. The results indicate that the convective heat-transfer coefficients and heat flux increase as humidity increase and temperature decrease. And it results in the increase of cooling rate and the decrease of phase transformation temperature of steel. According to the empirical relationship between the isothermal transformation temperature and experimental results of ultimate tensile strength with steel of SWRH82B and diameter of 12.5 mm, the maximum ultimate tensile strength (UTS) is 1206 MPa at −15 °C and humidity level of 100%, and the minimum UTS is 1139 MPa at 55 °C and humidity level of 0%. The predicted results agree well with the inspection results of industrial trials. And then, some references of the optimal outputs of blower have been provided for stabilizing product quality.
