The invention discloses a method for producing NM600 low alloy wear-resistant steel through a conventional hot continuous rolling line. The method comprises the steps that the mass percentage contentsof all elements in the steel are well controlled; qualified molten steel obtained after smelting is subjected to LF refining station argon blowing, RH vacuum degassing and calcium treatment and thencontinuous casting, so that a continuous casting blank with the thickness being 230 mm is obtained; the continuous casting blank is heated to 1180-1230 DEG C in a heating furnace, and heat preservation is conducted for 25 minutes or longer; firstly, rolling is conducted through a rough mill, wherein the rolling rate of each pass of the rough mill is greater than or equal to 15%; after rough rolling, the continuous casting blank is delivered into a finish continuous rolling unit to be rolled, wherein the rolling rate of each rack of the finish continuous rolling unit is greater than or equal to10%, the temperature of a finish rolling inlet is 1000-1100 DEG C, and the finish final rolling temperature is 820-900 DEG C; a wear-resistant steel plate, with the thickness being 4.0-25.0 mm, obtained after finish rolling is cooled to 600-700 DEG C, and then, the wear-resistant steel plate is rolled into a steel roll; and the steel roll is air-cooled to the room temperature and then subjected to leveling and off-line heat treatment, wherein the quenching temperature is 850-930 DEG C, and the tempering temperature is 150-250 DEG C. Rm of the NM600 wear-resistant steel plate is greater than or equal to 1800 MPa; A50 is greater than or equal to 7%; HBW ranges from 570 HB to 630 HB; AKv achieved at the temperature of minus 40 DEG C is greater than or equal to 20 J; and the practical value is high.
