Abstract
The invention provides a tempering deformation technology for low-carbon micro-alloy steel containing a trace of vanadium element. The tempering deformation technology is characterized by comprising the following steps that firstly, the low-carbon micro-alloy steel containing 0.2% of carbon is quenched at the temperature of 930 DEG C; and secondly, after rapid heating is conducted to 460 DEG C and heat preservation is conducted for 5 min, warm rolling is rapidly achieved with the rolling speed of 0.8 m/s and 50% of rolling reduction to conduct tempering deformation treatment. According to the tempering deformation technology for the low-carbon micro-alloy steel containing a trace of vanadium element, compared with a conventional method, the tensile strength, the yield strength, the yield ratio, the ductility and the hardness value of the low-carbon micro-alloy steel can reach the ideal values.
