FIELD: metallurgy.
SUBSTANCE: continuously cast blank is obtained from steel containing the following, wt %: carbon 0.18-0.23, manganese 0.70-.10, silicium 0.17-0.37, chrome 0.40-0.70, nickel 0.40-0.70, molybdenum 0.15-0.25, aluminium 0.002-0.040, sulphur 0.035-0.040, phosphorus not more than 0.035, iron and residual elements - the rest. Obtained blank is heated to 1150-1270°C and it is subject to roughing rolling and then to multipass finish rolling. At that in the last three passes finish rolling is performed in pass sequence "circle-oval-circle" in the temperature range from 1000-1100°C to 850-950°C with elongation ratio 1.10-1.25 in each of them.
EFFECT: improving quality and round rolled stock yield.
