The invention discloses a method for rolling rods with 150 square blanks and 165 square blanks through both rough rolling and intermediate rolling. According to the method, six rough rolling mills and four to six intermediate rolling mills are used, wherein no-groove rolling is adopted by the rough rolling mills from t1# to 5#, round hole rolling is adopted by the 6# rough rolling mill, round-oval hole rolling is adopted by the intermediate rolling mills, when five intermediate rolling mills are adopted, the 7# intermediate rolling mill idles, and when six intermediate rolling mills are adopted, the 7# intermediate rolling mill and the 8# intermediate rolling mill idle. According to the method, no-groove rolling is adopted by the racks from 1# to 5#, and the rough rolling hole type and the intermediate rolling hole type are combined into one series; original 12 hole type passes are reduced to 10 passes by changing extending coefficients, the intermediate rolling speed is increased through the speed reduction
