Method of hot rolling of steel strip, including compression in a continuous multi-stand mill and regulation of relative reduction in the last stand within 5-25% as a function of speed and temperature of rolling in this stand when the speed changes in the range of 8-30 m / s and temperature in the range of 780 -920 0, characterized in that, in order to increase the uniformity of the structure and mechanical properties of the strip, the reduction regulation is carried out in accordance with the dependence (V, / t t) W Tj, respectively. Where the compression, speed and temperature (L tour pr rolls, T - the current values of the same parameters; a 0.6 n 1.0, 2 m 5. e |
