A method of hot rolling includes heating billet, deformation into several passages, cooling down of the surface of rolled metal and subsequent rolling into several passages. Cooling is produced for 2-10% of temperature of breakdown bar in previous passage. The subsequent rolling is performed with the coefficient of friction of 0.8-0.95 of the coefficients of friction of breakdown bar in the previous passage.
