the productimeter) to 0.7-1.1 mm and 0.5-0.9 mm, respectively, depending on the thickness of the rolled strip. The scheme of rolling speed mode in НСХП 1700 (1680) is presented in Figure 1 where Lfe - length of the front end of the rolled strip during threading; Lbe - length of the bottom end of the rolled strip during slowing down the of the mill; Ld and Lc – strip length between the stand № 1 and in the decoiler and in the coiler respectively; Lac, Lsl - strip length during the periods of acceleration and slowing down, respectively; vfe,vs, vbe, vх - rolling speed, respectively, when threading the front end of the strip in the coiler, maximum in the steady process, with the release of the bottom end and the speed corresponding to the intensive change of friction coefficient (for vх < 5 m/sec friction coefficient increases significantly with

The influence of the rolling parameters on microstructure and texture formation over 01 ЮT steel strip and on its capacity for profound extension is investigated. It is found that the capacity for profound extension in a 01 ЮT steel sample deformed in the austenitic state and cooled in air may be attributed to the higher concentration of small-angle boundaries and special boundaries Σ3 60° <111> than in steel for which rolling ends at subcritical temperatures.
