| Abstract: | Adding proper amount VN alloy to 20MnSi steel produced φ22~φ32 mm HRB400 hot-rolled ribbed steel bars by microalloy and rapid cooling process after rolling.Analyzing the influence of VN alloy on the structure and properties confirmed the adding amount of the vanadium as 0.04% ~ 0.06%.Through strict control of rolling rhythm,minus tolerance rolling,controlling the initial rolling temperature in 1 070 ~ 1 150 ℃ and combining with control cooling after the finish rolling,the mechanical properties of the products all reached the demands of the national standard. |
