Abstract
Способ изготовления холоднокатаной ленты из низкоуглеродистой стали преимущественно толщиной 0,5-0,6 мм, включающий удаление окалины с поверхности горячекатаного подката травлением, холодную прокатку на непрерывном стане и последующий ступенчатый рекристаллизационный отжиг рулонов, отличающийся тем, что при содержании в стали 0,13-0,17% углерода и 0,4-0,7% марганца производят предварительную термообработку горячекатаного травленого подката при температуре 560-590°С продолжительностью 9-11 ч, а холодную прокатку термообработанного подката производят с суммарным относительным обжатием 72-76%.A method of manufacturing a cold rolled strip of low carbon steel, preferably 0.5-0.6 mm thick, comprising descaling from the surface of the hot rolled tin by pickling, cold rolling on a continuous mill and subsequent stepwise recrystallization annealing of the rolls, characterized in that when the steel content is 0.13 -0.17% of carbon and 0.4-0.7% of manganese pretreat the hot-rolled pickled rolled product at a temperature of 560-590 ° C for a duration of 9-11 hours, and cold rolling the heat-treated rolled product produced dressed with a total relative compression of 72-76%.
